+> ![Tip](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) Cette intégration de thermostat vise à simplifier considérablement vos automatisations autour de la gestion du chauffage. Parce que tous les événements autour du chauffage classiques sont gérés nativement par le thermostat (personne à la maison ?, activité détectée dans une pièce ?, fenêtre ouverte ?, délestage de courant ?), vous n'avez pas à vous encombrer de scripts et d'automatismes compliqués pour gérer vos climats. ;-).

Dans ce mode, les switchs sont déclenchés avec un délai pour minimiser la puissance nécessaire à un instant (on minimise les périodes de recouvrement). Voir [Configuration](#sélectionnez-des-entités-pilotées)
+> * **Release 3.1** : ajout d'une détection de fenêtres/portes ouvertes par chute de température. Cette nouvelle fonction permet de stopper automatiquement un radiateur lorsque la température chute brutalement. Voir [Le mode auto](#le-mode-auto)
+> * **Release majeure 3.0** : ajout d'un équipement thermostat et de capteurs (binaires et non binaires) associés. Beaucoup plus proche de la philosphie Home Assistant, vous avez maintenant un accès direct à l'énergie consommée par le radiateur piloté par le thermostat et à plein d'autres capteurs qui seront utiles dans vos automatisations et dashboard.
+> * **release 2.3** : ajout de la mesure de puissance et d'énergie du radiateur piloté par le thermostat.
+> * **release 2.2** : ajout de fonction de sécurité permettant de ne pas laisser éternellement en chauffe un radiateur en cas de panne du thermomètre
+> * **release majeure 2.0** : ajout du thermostat "over climate" permettant de transformer n'importe quel thermostat en Versatile Thermostat et lui ajouter toutes les fonctions de ce dernier.

+
+
+# Quand l'utiliser et ne pas l'utiliser
+Ce thermostat peut piloter 2 types d'équipement:
+1. un radiateur qui ne fonctionne qu'en mode marche/arrêt (nommé ```thermostat_over_switch```). La configuration minimale nécessaire pour utiliser ce type thermostat est :
+   a. un équipement comme un radiateur (un ```switch``` ou équivalent),
+   b. une sonde de température pour la pièce (ou un input_number),
+   c. un capteur de température externe (pensez à l'intégration météo si vous n'en avez pas)
+2. un autre thermostat qui a ses propres modes de fonctionnement (nommé ```thermostat_over_climate```). Pour ce type de thermostat la configuration minimale nécessite :
+   a. un équipement comme une climatisation qui est pilotée par sa propre entity de type ```climate```,
+   b. une sonde de température pour la pièce (ou un input_number),
+   c. un capteur de température externe (pensez à l'intégration météo si vous n'en avez pas)
+
+Le type ```thermostat_over_climate``` permet d'ajouter à votre équipement existant toutes les fonctionnalités fournies par VersatileThermostat. L'entité climate VersatileThermostat pilotera votre entité climate, en la coupant si les fenêtres sont ouvertes, la passant en mode Eco si personne n'est présent, etc. Cf. [ici](#pourquoi-une-nouvelle-implémentation-du-thermostat). Pour ce type de thermostat, les cycles éventuels de chauffe sont pilotés par l'entité climate sous-jacente et pas par le Versatile Thermostat lui-même.
+
+Parce que cette intégration vise à commander le radiateur en tenant compte du préréglage configuré (preset) et de la température ambiante, ces informations sont obligatoires.
+
+# Pourquoi une nouvelle implémentation du thermostat ?
+
+Ce composant nommé __Versatile thermostat__ gère les cas d'utilisation suivants :
+- Configuration via l'interface graphique d'intégration standard (à l'aide du flux Config Entry),
+- Utilisations complètes du **mode préréglages**,
+- Désactiver le mode préréglé lorsque la température est **définie manuellement** sur un thermostat,
+- Éteindre/allumer un thermostat lorsqu'une **porte ou des fenêtres sont ouvertes/fermées** après un certain délai,
+- Changer de preset lorsqu'une **activité est détectée** ou non dans une pièce pendant un temps défini,
+- Utiliser un algorithme **TPI (Time Proportional Interval)** grâce à l'algorithme [[Argonaute](https://forum.hacf.fr/u/argonaute/summary)] ,
+- Ajouter une **gestion de délestage** ou une régulation pour ne pas dépasser une puissance totale définie. Lorsque la puissance maximale est dépassée, un préréglage caché de « puissance » est défini sur l'entité climatique. Lorsque la puissance passe en dessous du maximum, le préréglage précédent est restauré.
+- La **gestion de la présence à domicile**. Cette fonctionnalité vous permet de modifier dynamiquement la température du préréglage en tenant compte d'un capteur de présence de votre maison.
+- Des **services pour interagir avec le thermostat** à partir d'autres intégrations : vous pouvez forcer la présence / la non-présence à l'aide d'un service, et vous pouvez modifier dynamiquement la température des préréglages et changer les paramètres de sécurité.
+- Ajouter des capteurs pour voir les états internes du thermostat.
+
+# Comment installer cet incroyable Thermostat Versatile ?
+
+## HACS installation (recommendé)
+
+1. Installez [HACS](https://hacs.xyz/). De cette façon, vous obtenez automatiquement les mises à jour.
+2. Ajoutez ce repository Github en tant que repository personnalisé dans les paramètres HACS.
+3. recherchez et installez "Versatile Thermostat" dans HACS et cliquez sur "installer".
+4. Redémarrez Home Assistant.
+5. Ensuite, vous pouvez ajouter une intégration de Versatile Thermostat dans la page d'intégration. Vous ajoutez autant de thermostats dont vous avez besoin (généralement un par radiateur qui doit être géré ou par pompe dans le cas d'un chauffage centralisé)
+
+
+## Installation manuelle
+
+1. À l'aide de l'outil de votre choix, ouvrez le répertoire (dossier) de votre configuration HA (où vous trouverez `configuration.yaml`).
+2. Si vous n'avez pas de répertoire (dossier) `custom_components`, vous devez le créer.
+3. Dans le répertoire (dossier) `custom_components`, créez un nouveau dossier appelé `versatile_thermostat`.
+4. Téléchargez _tous_ les fichiers du répertoire `custom_components/versatile_thermostat/` (dossier) dans ce référentiel.
+5. Placez les fichiers que vous avez téléchargés dans le nouveau répertoire (dossier) que vous avez créé.
+6. Redémarrez l'assistant domestique
+7. Configurer la nouvelle intégration du Versatile Thermostat
+
+# Configuration
+
+Note: aucune configuration dans configuration.yaml n'est nécessaire car toute la configuration est effectuée via l'interface graphique standard lors de l'ajout de l'intégration.

+La configuration peut être modifiée via la même interface. Sélectionnez simplement le thermostat à modifier, appuyez sur "Configurer" et vous pourrez modifier certains paramètres ou la configuration.
+
+Suivez ensuite les étapes de configuration comme suit :
+
+## Choix des attributs de base
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-main.png?raw=true)
+
+Donnez les principaux attributs obligatoires :
+1. un nom (sera le nom de l'intégration et aussi le nom de l'entité climate)
+2. le type de thermostat ```thermostat_over_switch``` pour piloter un radiateur commandé par un switch ou ```thermostat_over_climate``` pour piloter un autre thermostat. Cf. [ci-dessus](#pourquoi-une-nouvelle-implémentation-du-thermostat)
+4. un identifiant d'entité de capteur de température qui donne la température de la pièce dans laquelle le radiateur est installé,
+5. une entité capteur de température donnant la température extérieure. Si vous n'avez pas de capteur externe, vous pouvez utiliser l'intégration météo locale
+6. une durée de cycle en minutes. A chaque cycle, le radiateur s'allumera puis s'éteindra pendant une durée calculée afin d'atteindre la température ciblée (voir [preset](#configure-the-preset-temperature) ci-dessous),
+7. les températures minimales et maximales du thermostat,
+8. une puissance de l'équipement ce qui va activer les capteurs de puissance et énergie consommée par l'appareil,
+9. la liste des fonctionnalités qui seront utilisées pour ce thermostat. En fonction de vos choix, les écrans de configuration suivants s'afficheront ou pas.
+
+> ![Astuce](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Notes*_
+      1. avec le type ```thermostat_over_swutch```, les calculs sont effectués à chaque cycle. Donc en cas de changement de conditions, il faudra attendre le prochain cycle pour voir un changement. Pour cette raison, le cycle ne doit pas être trop long. **5 min est une bonne valeur**,
+      2. si le cycle est trop court, le radiateur ne pourra jamais atteindre la température cible en effet pour le radiateur à accumulation et il sera sollicité inutilement
+
+## Sélectionnez des entités pilotées
+En fonction de votre choix sur le type de thermostat, vous devrez choisir une ou plusieurs entités de type switch ou une entité de type climate. Seules les entités compatibles sont présentées.
+
+Pour un thermostat de type ```thermostat_over_switch```:
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-linked-entity.png?raw=true)
+L'algorithme à utiliser est aujourd'hui limité à TPI est disponible. Voir [algorithme](#algorithme).
+Si plusieurs entités de type sont configurées, la thermostat décale les activations afin de minimiser le nombre de switch actif à un instant t. Ca permet une meilleure répartition de la puissance puisque chaque radiateur va s'allumer à son tour.
+Exemple de déclenchement synchronisé :
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/multi-switch-activation.png?raw=true)
+
+
+Pour un thermostat de type ```thermostat_over_climate```:
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-linked-entity2.png?raw=true)
+
+## Configurez les coefficients de l'algorithme TPI
+
+Si vous avez choisi un thermostat de type ```thermostat_over_switch``` vous arriverez sur cette page :
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-tpi.png?raw=true)
+
+Vous devez donner :
+1. le coefficient coef_int de l'algorithme TPI,
+2. le coefficient coef_ext de l'algorithme TPI
+
+
+Pour plus d'informations sur l'algorithme TPI et son réglage, veuillez vous référer à [algorithm](#algorithm).
+
+## Configurer la température préréglée
+Cliquez sur 'Valider' sur la page précédente et vous y arriverez :
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-presets.png?raw=true)
+
+Le mode préréglé (preset) vous permet de préconfigurer la température ciblée. Utilisé en conjonction avec Scheduler (voir [scheduler](#even-better-with-scheduler-component) vous aurez un moyen puissant et simple d'optimiser la température par rapport à la consommation électrique de votre maison. Les préréglages gérés sont les suivants :
+ - **Eco** : l'appareil est en mode d'économie d'énergie
+ - **Confort** : l'appareil est en mode confort
+ - **Boost** : l'appareil tourne toutes les vannes à fond
+
+**Aucun** est toujours ajouté dans la liste des modes, car c'est un moyen de ne pas utiliser les preset mais une **température manuelle** à la place.
+
+> ![Astuce](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Notes*_
+    1. En modifiant manuellement la température cible, réglez le préréglage sur Aucun (pas de préréglage). De cette façon, vous pouvez toujours définir une température cible même si aucun préréglage n'est disponible.
+    2. Le préréglage standard ``Away`` est un préréglage caché qui n'est pas directement sélectionnable. Versatile Thermostat utilise la gestion de présence ou la gestion de mouvement pour régler automatiquement et dynamiquement la température cible en fonction d'une présence dans le logement ou d'une activité dans la pièce. Voir [gestion de la présence](#configure-the-presence-management).
+    3. Si vous utilisez la gestion du délestage, vous verrez un préréglage caché nommé ``power``. Le préréglage de l'élément chauffant est réglé sur « puissance » lorsque des conditions de surpuissance sont rencontrées et que le délestage est actif pour cet élément chauffant. Voir [gestion de l'alimentation](#configure-the-power-management).
+    4. si vous utilisez la configuration avancée, vous verrez le préréglage défini sur ``sécurité`` si la température n'a pas pu être récupérée après un certain délai
+    5. Si vous ne souhaitez pas utiliser le préréglage, indiquez 0 comme température. Le préréglage sera alors ignoré et ne s'affichera pas dans le composant front
+
+## Configurer les portes/fenêtres en allumant/éteignant les thermostats
+Vous devez avoir choisi la fonctionnalité ```Avec détection des ouvertures``` dans la première page pour arriver sur cette page.
+La détecttion des ouvertures peut se faire de 2 manières:
+1. soit avec un capteur placé sur l'ouverture (mode capteur),
+2. soit en détectant une chute brutale de température (mode auto)
+
+### Le mode capteur
+En mode capteur, vous devez renseigner les informations suivantes:
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-window-sensor.png?raw=true)
+
+1. un identifiant d'entité d'un **capteur de fenêtre/porte**. Cela devrait être un binary_sensor ou un input_boolean. L'état de l'entité doit être 'on' lorsque la fenêtre est ouverte ou 'off' lorsqu'elle est fermée
+2. un **délai en secondes** avant tout changement. Cela permet d'ouvrir rapidement une fenêtre sans arrêter le chauffage.
+
+
+### Le mode auto
+En mode auto, la configuration est la suivante:
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-window-auto.png?raw=true)
+
+1. un seuil de détection en degré par minute. Lorsque la température chute au delà de ce seuil, le thermostat s'éteindra. Plus cette valeur est faible et plus la détection sera rapide (en contre-partie d'un risque de faux positif),
+2. un seuil de fin de détection en degré par minute. Lorsque la chute de température repassera au-dessus cette valeur, le thermostat se remettra dans le mode précédent (mode et preset),
+3. une durée maximale de détection. Au delà de cette durée, le thermostat se remettra dans son mode et preset précédent même si la température continue de chuter.
+
+Pour régler les seuils il est conseillé de commencer avec les valeurs de référence et d'ajuster les seuils de détection. Quelques essais m'ont donné les valeurs suivantes (pour un bureau):
+- seuil de détection : 0,05 °C/min
+- seuil de non détection: 0 °C/min
+- durée max : 60 min.
+
+Un nouveau capteur "slope" a été ajouté pour tous les thermostats. Il donne la pente de la courbe de température en °C/min (ou °K/min). Cette pente est lissée et filtrée pour éviter les valeurs abérrantes des thermomètres qui viendraient pertuber la mesure.
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/temperature-slope.png?raw=true)
+
+Pour bien régler il est conseillé d'affocher sur un même graphique historique la courbe de température et la pente de la courbe (le "slope") :
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/window-auto-tuning.png?raw=true)
+
+Et c'est tout ! votre thermostat s'éteindra lorsque les fenêtres seront ouvertes et se rallumera lorsqu'il sera fermé.
+
+> ![Astuce](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Notes*_
+    1. Si vous souhaitez utiliser **plusieurs capteurs de porte/fenêtre** pour automatiser votre thermostat, créez simplement un groupe avec le comportement habituel (https://www.home-assistant.io/integrations/binary_sensor.group/)
+    2. Si vous n'avez pas de capteur de fenêtre/porte dans votre chambre, laissez simplement l'identifiant de l'entité du capteur vide,
+    3. **Un seul mode est permis**. On ne peut pas configurer un thermostat avec un capteur et une détection automatique. Les 2 modes risquant de se contredire, il n'est pas possible d'avoir les 2 modes en même temps,
+    4. Il est déconseillé d'utiliser le mode automatique pour un équipement soumis à des variations de température fréquentes et normales (couloirs, zones ouvertes, ...)
+
+## Configurer le mode d'activité ou la détection de mouvement
+Si vous avez choisi la fonctionnalité ```Avec détection de mouvement```, cliquez sur 'Valider' sur la page précédente et vous y arriverez :
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-motion.png?raw=true)
+
+Nous allons maintenant voir comment configurer le nouveau mode Activité.
+Ce dont nous avons besoin:
+- un **capteur de mouvement**. ID d'entité d'un capteur de mouvement. Les états du capteur de mouvement doivent être « on » (mouvement détecté) ou « off » (aucun mouvement détecté)
+- une durée de **délai de mouvement** (en secondes) définissant combien de temps nous attendons la confirmation du mouvement avant de considérer le mouvement
+- un **préréglage de "mouvement" **. Nous utiliserons la température de ce préréglage lorsqu'une activité sera détectée.
+- un **préréglage "pas de mouvement"**. Nous utiliserons la température de ce deuxième préréglage lorsqu'aucune activité n'est détectée.
+
+Alors imaginons que nous voulions avoir le comportement suivant :
+- nous avons une pièce avec un thermostat réglé en mode activité, le mode "mouvement" choisi est confort (21.5C), le mode "pas de mouvement" choisi est Eco (18.5C) et la temporisation du mouvement est de 5 min.
+- la pièce est vide depuis un moment (aucune activité détectée), la température de cette pièce est de 18,5 C
+- quelqu'un entre dans la pièce, une activité est détectée la température est fixée à 21,5 C
+- la personne quitte la chambre, au bout de 5 min la température est ramenée à 18,5 C
+
+Pour que cela fonctionne, le thermostat climatique doit être en mode préréglé « Activité ».
+
+> ![Astuce](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Notes*_
+    1. Sachez que comme pour les autres modes prédéfinis, ``Activity`` ne sera proposé que s'il est correctement configuré. En d'autres termes, les 4 clés de configuration doivent être définies si vous souhaitez voir l'activité dans l'interface de l'assistant domestique
+
+## Configurer la gestion de la puissance
+
+Si vous avez choisi la fonctionnalité ```Avec détection de la puissance```, cliquez sur 'Valider' sur la page précédente et vous arriverez ici :
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-power.png?raw=true)
+
+Cette fonction vous permet de réguler la consommation électrique de vos radiateurs. Connue sous le nom de délestage, cette fonction vous permet de limiter la consommation électrique de votre appareil de chauffage si des conditions de surpuissance sont détectées. Donnez un **capteur à la consommation électrique actuelle de votre maison**, un **capteur à la puissance max** qu'il ne faut pas dépasser, la **consommation électrique de votre chauffage** (en étape 1 de la configuration) et l'algorithme ne démarrera pas un radiateur si la puissance maximale sera dépassée après le démarrage du radiateur.
+
+Notez que toutes les valeurs de puissance doivent avoir les mêmes unités (kW ou W par exemple).
+Cela vous permet de modifier la puissance maximale au fil du temps à l'aide d'un planificateur ou de ce que vous voulez.
+
+> ![Astuce](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Notes*_
+    1. En cas de délestage, le radiateur est réglé sur le préréglage nommé ```power```. Il s'agit d'un préréglage caché, vous ne pouvez pas le sélectionner manuellement.
+    2. Je l'utilise pour éviter de dépasser la limite de mon contrat d'électricité lorsqu'un véhicule électrique est en charge. Cela crée une sorte d'autorégulation.
+    3. Gardez toujours une marge, car la puissance max peut être brièvement dépassée en attendant le calcul du prochain cycle typiquement ou par des équipements non régulés.
+    4. Si vous ne souhaitez pas utiliser cette fonctionnalité, laissez simplement l'identifiant des entités vide
+
+## Configurer la présence ou l'occupation
+Si sélectionnée en première page, cette fonction vous permet de modifier dynamiquement la température de tous les préréglages du thermostat configurés lorsque personne n'est à la maison ou lorsque quelqu'un rentre à la maison. Pour cela, vous devez configurer la température qui sera utilisée pour chaque préréglage lorsque la présence est désactivée. Lorsque le capteur de présence s'éteint, ces températures seront utilisées. Lorsqu'il se rallume, la température "normale" configurée pour le préréglage est utilisée. Voir [gestion des préréglages](#configure-the-preset-temperature).
+Pour configurer la présence remplissez ce formulaire :
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-presence.png?raw=true)
+
+Pour cela, vous devez configurer :
+1. Un **capteur d'occupation** dont l'état doit être 'on' ou 'home' si quelqu'un est présent ou 'off' ou 'not_home' sinon,
+2. La **température utilisée en Eco** prédéfinie en cas d'absence,
+3. La **température utilisée en Confort** préréglée en cas d'absence,
+4. La **température utilisée en Boost** préréglée en cas d'absence
+
+> ![Astuce](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Notes*_
+      1. le changement de température est immédiat et se répercute sur le volet avant. Le calcul prendra en compte la nouvelle température cible au prochain calcul du cycle,
+      2. vous pouvez utiliser le capteur direct person.xxxx ou un groupe de capteurs de Home Assistant. Le capteur de présence gère les états ``on`` ou ``home`` comme présents et les états ``off`` ou ``not_home`` comme absents.
+
+## Configuration avancée
+Ces paramètres permettent d'affiner le réglage du thermostat.
+Le formulaire de configuration avancée est le suivant :
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-advanced.png?raw=true)
+
+Le premier délai (minimal_activation_delay_sec) en secondes est le délai minimum acceptable pour allumer le chauffage. Lorsque le calcul donne un délai de mise sous tension inférieur à cette valeur, le chauffage reste éteint.
+
+Le deuxième délai (``security_delay_min``) est le délai maximal entre deux mesures de température avant de régler le préréglage sur ``security``. Si le capteur de température ne donne plus de mesures de température, le thermostat et le radiateur passeront en mode ``security`` après ce délai. Ceci est utile pour éviter une surchauffe si la batterie de votre capteur de température est trop faible.
+
+Le troisième paramétre (``security_min_on_percent``) est la valeur minimal de ``on_percent`` en dessous de laquelle le préréglage sécurité ne sera pas activé. Ce paramètre permet de ne pas mettre en sécurité un thermostat, si le radiateur piloté ne chauffe pas suffisament.
+Mettre ce paramètre à ``0.00`` déclenchera le préréglage sécurité quelque soit la dernière consigne de chauffage, à l'inverse ``1.00`` ne déclenchera jamais le préréglage sécurité ( ce qui revient à désactiver la fonction).
+
+Le quatrième param§tre (``security_default_on_percent``) est la valeur de ``on_percent`` qui sera utilisée lorsque le thermostat passe en mode ``security``. Si vous mettez ``0`` alors le thermostat sera coupé lorsqu'il passe en mode ``security``, mettre 0,2% par exemple permet de garder un peu de chauffage (20% dans ce cas), même en mode ``security``. Ca évite de retrouver son logement totalement gelé lors d'une panne de thermomètre.
+
+Voir [exemple de réglages](#examples-tuning) pour avoir des exemples de réglage communs
+
+> ![Astuce](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Notes*_
+    1. Lorsque le capteur de température viendra à la vie et renverra les températures, le préréglage sera restauré à sa valeur précédente,
+    3. Attention, deux températures sont nécessaires : la température interne et la température externe et chacune doit donner la température, sinon le thermostat sera en préréglage "security",
+    4. Un service est disponible qui permet de régler les 3 paramètres de sécurité. Ca peut servir à adapter la fonction de sécurité à votre usage,
+    5. Pour un usage naturel, le ``security_default_on_percent`` doit être inférieur à ``security_min_on_percent``,
+    6. Lorsqu'un thermostat de type ``thermostat_over_climate`` passe en mode ``security`` il est éteint. Les paramètres ``security_min_on_percent`` et ``security_default_on_percent`` ne sont alors pas utilisés.
+
+# Exemples de réglage
+
+## Chauffage électrique
+- cycle : entre 5 et 10 minutes,
+- minimal_activation_delay_sec : 30 secondes
+
+## Chauffage central (chauffage gaz ou fuel)
+- cycle : entre 30 et 60 min,
+- minimal_activation_delay_sec : 300 secondes (à cause du temps de réponse)
+
+## Le capteur de température alimenté par batterie
+- security_delay_min : 60 min (parce que ces capteurs sont paresseux)
+- security_min_on_percent : 0,5 (50% - on passe en preset ``security`` si le radiateur chauffait plus de 50% du temps)
+- security_default_on_percent : 0,1 (10% - en preset ``security``, on garde un fond de chauffe de 20% du temps)
+
+Il faut comprendre ces réglages comme suit :
+
+> Si le thermomètre n'envoie plus la température pendant 1 heure et que le pourcentage de chauffe (``on_percent``) était supérieur à 50 %, alors on ramène ce pourcentage de chauffe à 10 %.
+
+A vous d'adapter ces réglages à votre cas !
+
+Ce qui est important c'est de ne pas prendre trop de risque avec ces paramètres : supposez que vous êtes absent pour une longue période, que les piles de votre thermomètre arrivent en fin de vie, votre radiateur va chauffer 10% du temps pendant toute la durée de la panne.
+
+Versatile Thermostat vous permet d'être notifié lorsqu'un évènement de ce type survient. Mettez en place, les alertes qui vont bien dès l'utilisation de ce thermostat. Cf. (#notifications)
+
+## Capteur de température réactif (sur secteur)
+- security_delay_min : 15 min
+- security_min_on_percent : 0,7 (70% - on passe en preset ``security`` si le radiateur chauffait plus de 70% du temps)
+- security_default_on_percent : 0,25 (25% - en preset ``security``, on garde un fond de chauffe de 25% du temps)
+
+## Mes presets
+Ceci est juste un exemple de la façon dont j'utilise le préréglage. A vous de vous adapter à votre configuration mais cela peut être utile pour comprendre son fonctionnement.
+``Éco`` : 17 °C
+``Confort`` : 19 °C
+``Boost`` : 20 °C
+
+Lorsque la présence est désactivée :
+``Éco`` : 16,5 °C
+``Confort`` : 17 °C
+``Boost`` : 18 °C
+
+Le détecteur de mouvement de mon bureau est configuré pour utiliser ``Boost`` lorsqu'un mouvement est détecté et ``Eco`` sinon.
+
+# Algorithme
+Cette intégration utilise un algorithme proportionnel. Un algorithme proportionnel est utile pour éviter l'oscillation autour de la température cible. Cet algorithme est basé sur un cycle qui alterne le chauffage et l'arrêt du chauffage. La proportion de chauffage par rapport à l'absence de chauffage est déterminée par la différence entre la température et la température cible. Plus grande est la différence et plus grande est la proportion de chauffage à l'intérieur du cycle.
+
+Cet algorithme fait converger la température et arrête d'osciller.
+
+## Algorithme TPI
+L'algorithme TPI consiste à calculer à chaque cycle un pourcentage d'état On vs Off pour le radiateur en utilisant la température cible, la température actuelle dans la pièce et la température extérieure actuelle.
+
+Le pourcentage est calculé avec cette formule :
+
+    on_percent = coef_int * (température cible - température actuelle) + coef_ext * (température cible - température extérieure)
+    Ensuite, faites 0 <= on_percent <= 1
+
+Les valeurs par défaut pour coef_int et coef_ext sont respectivement : ``0.6`` et ``0.01``. Ces valeurs par défaut conviennent à une pièce standard bien isolée.
+
+Pour régler ces coefficients, gardez à l'esprit que :
+1. **si la température cible n'est pas atteinte** après une situation stable, vous devez augmenter le ``coef_ext`` (le ``on_percent`` est trop bas),
+2. **si la température cible est dépassée** après une situation stable, vous devez diminuer le ``coef_ext`` (le ``on_percent`` est trop haut),
+3. **si l'atteinte de la température cible est trop lente**, vous pouvez augmenter le ``coef_int`` pour donner plus de puissance au réchauffeur,
+4. **si l'atteinte de la température cible est trop rapide et que des oscillations apparaissent** autour de la cible, vous pouvez diminuer le ``coef_int`` pour donner moins de puissance au radiateur
+
+Voir quelques situations à [examples](#some-results).
+
+# Capteurs
+
+Avec le thermostat sont disponibles des capteurs qui permettent de visualiser les alertes et l'état interne du thermostat. Ils sont disponibles dans les entités de l'appareil associé au thermostat :
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/thermostat-sensors.png?raw=true)
+
+Dans l'ordre, il y a :
+1. l'entité principale climate de commande du thermostat,
+2. l'énergie consommée par le thermostat (valeur qui s'incrémente en permanence),
+3. l'heure de réception de la dernière température extérieure,
+4. l'heure de réception de la dernière température intérieure,
+5. la puissance moyenne de l'appareil sur le cycle (pour les TPI seulement),
+6. le temps passé à l'état éteint dans le cycle (TPI seulement),
+7. le temps passé à l'état allumé dans le cycle (TPI seulement),
+8. l'état de délestage,
+9. le pourcentage de puissance sur le cycle (TPI seulement),
+10. l'état de présence (si la gestion de la présence est configurée),
+11. l'état de sécurité,
+12. l'état de l'ouverture (si la gestion des ouvertures est configurée),
+13. l'état du mouvement (si la gestion du mouvements est configurée)
+
+Pour colorer les capteurs, ajouter ces lignes et personnalisez les au besoin, dans votre configuration.yaml :
+
+```
+frontend:
+  themes:
+    versatile_thermostat_theme:
+      state-binary_sensor-safety-on-color: "#FF0B0B"
+      state-binary_sensor-power-on-color: "#FF0B0B"
+      state-binary_sensor-window-on-color: "rgb(156, 39, 176)"
+      state-binary_sensor-motion-on-color: "rgb(156, 39, 176)"
+      state-binary_sensor-presence-on-color: "lightgreen"
+```
+et choisissez le thème ```versatile_thermostat_theme``` dans la configuration du panel. Vous obtiendrez quelque-chose qui va ressembler à ça :
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/colored-thermostat-sensors.png?raw=true)
+
+# Services
+
+Cette implémentation personnalisée offre des services spécifiques pour faciliter l'intégration avec d'autres composants Home Assistant.
+
+## Forcer la présence/occupation
+Ce service permet de forcer l'état de présence indépendamment du capteur de présence. Cela peut être utile si vous souhaitez gérer la présence via un service et non via un capteur. Par exemple, vous pouvez utiliser votre réveil pour forcer l'absence lorsqu'il est allumé.
+
+Le code pour appeler ce service est le suivant :
+```
+service : thermostat_polyvalent.set_presence
+Les données:
+    présence : "off"
+cible:
+    entity_id : climate.my_thermostat
+```
+
+## Modifier la température des préréglages
+Ce service est utile si vous souhaitez modifier dynamiquement la température préréglée. Au lieu de changer de préréglage, certains cas d'utilisation doivent modifier la température du préréglage. Ainsi, vous pouvez garder le Programmateur inchangé pour gérer le préréglage et ajuster la température du préréglage.
+Si le préréglage modifié est actuellement sélectionné, la modification de la température cible est immédiate et sera prise en compte au prochain cycle de calcul.
+
+Vous pouvez modifier l'une ou les deux températures (lorsqu'elles sont présentes ou absentes) de chaque préréglage.
+
+Utilisez le code suivant pour régler la température du préréglage :
+```
+service : thermostat_polyvalent.set_preset_temperature
+date:
+    preset : boost
+    temperature : 17,8
+    temperature_away : 15
+target:
+    entity_id : climate.my_thermostat
+```
+
+> ![Astuce](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Notes*_
+    - après un redémarrage, les préréglages sont réinitialisés à la température configurée. Si vous souhaitez que votre changement soit permanent, vous devez modifier le préréglage de la température dans la configuration de l'intégration.
+
+## Modifier les paramètres de sécurité
+Ce service permet de modifier dynamiquement les paramètres de sécurité décrits ici [Configuration avancée](#configuration-avancée).
+Si le thermostat est en mode ``security`` les nouveaux paramètres sont appliqués immédiatement.
+
+Pour changer les paramètres de sécurité utilisez le code suivant :
+```
+service : thermostat_polyvalent.set_security
+date:
+    min_on_percent: "0.5"
+    default_on_percent: "0.1"
+    delay_min: 60
+target:
+    entity_id : climate.my_thermostat
+```
+
+# Notifications
+Les évènements marquant du thermostat sont notifiés par l'intermédiaire du bus de message.
+Les évènements notifiés sont les suivants: 
+
+- ``versatile_thermostat_security_event`` : un thermostat entre ou sort du preset ``security``
+- ``versatile_thermostat_power_event`` : un thermostat entre ou sort du preset ``power``
+- ``versatile_thermostat_temperature_event`` : une ou les deux mesures de température d'un thermostat n'ont pas été mis à jour depuis plus de `security_delay_min`` minutes
+- ``versatile_thermostat_hvac_mode_event`` : le thermostat est allumé ou éteint. Cet évènement est aussi diffusé au démarrage du thermostat
+- ``versatile_thermostat_preset_event`` : un nouveau preset est sélectionné sur le thermostat. Cet évènement est aussi diffusé au démarrage du thermostat
+
+Si vous avez bien suivi, lorsqu'un thermostat passe en mode sécurité, 3 évènements sont déclenchés :
+1. ``versatile_thermostat_temperature_event`` pour indiquer qu'un thermomètre ne répond plus,
+2. ``versatile_thermostat_preset_event`` pour indiquer le passage en preset ```security```,
+3. ``versatile_thermostat_hvac_mode_event`` pour indiquer l'extinction éventuelle du thermostat
+
+Chaque évènement porte les valeurs clés de l'évènement (températures, preset courant, puissance courante, ...) ainsi que les états du thermostat.
+
+Vous pouvez très facilement capter ses évènements dans une automatisation par exemple pour notifier les utilisateurs.
+
+# Attributs personnalisés
+
+Pour régler l'algorithme, vous avez accès à tout le contexte vu et calculé par le thermostat via des attributs dédiés. Vous pouvez voir (et utiliser) ces attributs dans l'IHM "Outils de développement / états" de HA. Entrez votre thermostat et vous verrez quelque chose comme ceci :

+
+# Encore mieux
+
+## Encore mieux avec le composant Scheduler !
+
+Afin de profiter de toute la puissance du Versatile Thermostat, je vous invite à l'utiliser avec https://github.com/nielsfaber/scheduler-component
+En effet, le composant scheduler propose une gestion de la base climatique sur les modes prédéfinis. Cette fonctionnalité a un intérêt limité avec le thermostat générique mais elle devient très puissante avec le thermostat Awesome :
+
+À partir d'ici, je suppose que vous avez installé Awesome Thermostat et Scheduler Component.
+
+Dans Scheduler, ajoutez un planning :
+
+![image](https://user-images.githubusercontent.com/1717155/119146454-ee1a9d80-ba4a-11eb-80ae-3074c3511830.png)
+
+Choisissez le groupe "climat", choisissez une (ou plusieurs) entité(s), sélectionnez "MAKE SCHEME" et cliquez sur suivant :
+(il est possible de choisir "SET PRESET", mais je préfère utiliser "MAKE SCHEME")
+
+![image](https://user-images.githubusercontent.com/1717155/119147210-aa746380-ba4b-11eb-8def-479a741c0ba7.png)
+
+Définissez votre schéma de mode et enregistrez :

+
+Dans cet exemple, j'ai réglé le mode ECO pendant la nuit et le jour lorsqu'il n'y a personne à la maison BOOST le matin et CONFORT le soir.
+
+
+J'espère que cet exemple vous aidera, n'hésitez pas à me faire part de vos retours !
+
+## Encore bien mieux avec la custom:simple-thermostat front integration
+Le ``custom:simple-thermostat`` [ici](https://github.com/nervetattoo/simple-thermostat) est une excellente intégration qui permet une certaine personnalisation qui s'adapte bien à ce thermostat.
+Vous pouvez avoir quelque chose comme ça très facilement ![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/simple-thermostat.png?raw=true)
+Exemple de configuration :
+
+```
+      type: custom:simple-thermostat
+      entity: climate.thermostat_sam2
+      layout:
+        step: row
+      label:
+        temperature: T°
+        state: Etat
+      hide:
+        state: false
+      control:
+        hvac:
+          _name: Mode
+        preset:
+          _name: Preset
+      sensors:
+        - entity: sensor.total_puissance_radiateur_sam2
+          icon: mdi:lightning-bolt-outline
+      header:
+        toggle:
+          entity: input_boolean.etat_ouverture_porte_sam
+          name: Porte sam
+```
+
+Vous pouvez personnaliser ce composant à l'aide du composant HACS card-mod pour ajuster les couleurs des alertes. Exemple pour afficher en rouge les alertes sécurité et délestage :
+
+```
+          card_mod:
+            style: |
+              {% if is_state('binary_sensor.thermostat_chambre_security_state', 'on') %}
+              ha-card .body .sensor-heading ha-icon[icon="mdi:alert-outline"] {
+                color: red;
+              }
+              {% endif %}
+              {% if is_state('binary_sensor.thermostat_chambre_overpowering_state', 'on') %}
+              ha-card .body .sensor-heading ha-icon[icon="mdi:flash"] {
+                color: red;
+              }
+              {% endif %}
+```
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/custom-css-thermostat.png?raw=true)
+
+## Toujours mieux avec Apex-chart pour régler votre thermostat
+Vous pouvez obtenir une courbe comme celle présentée dans [some results](#some-results) avec une sorte de configuration de graphique Apex uniquement en utilisant les attributs personnalisés du thermostat décrits [ici](#custom-attributes) :
+
+```
+type: custom:apexcharts-card
+header:
+  show: true
+  title: Tuning chauffage
+  show_states: true
+  colorize_states: true

+
+## Et toujours de mieux en mieux avec l'AappDaemon NOTIFIER pour notifier les évènements
+Cette automatisation utilise l'excellente App Daemon nommée NOTIFIER développée par Horizon Domotique que vous trouverez en démonstration [ici](https://www.youtube.com/watch?v=chJylIK0ASo&ab_channel=HorizonDomotique) et le code est [ici](https://github.com/jlpouffier/home-assistant-config/blob/master/appdaemon/apps/notifier.py). Elle permet de notifier les utilisateurs du logement lorsqu'un des évènements touchant à la sécurité survient sur un des Versatile Thermostats.
+
+C'est un excellent exemple de l'utilisation des notifications décrites ici [notification](#notifications).

+> ![Tip](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) This thermostat integration aims to drastically simplify your automations around climate management. Because all classical events in climate are natively handled by the thermostat (nobody at home ?, activity detected in a room ?, window open ?, power shedding ?), you don't have to build over complicated scripts and automations to manage your climates ;-).

-_Component developed by using the amazing development template [blueprint][blueprint]._

 This custom component for Home Assistant is an upgrade and is a complete rewrite of the component "Awesome thermostat" (see [Github](https://github.com/dadge/awesome_thermostat)) with addition of features.

-## When to use / not use
-This thermostat aims to command a heater which works only in on/off mode. The minimal needed configuration to use this thermostat is:
-1. an equipement like a heater (a switch),
-2. a temperature sensor for the room (or an input_number),
-3. an external temperature sensor (think of the meteo integration if you don't have one)
+>![New](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/new-icon.png?raw=true) _*News*_
+> * **Release 3.2**: added the ability to control multiple switches from the same thermostat. In this mode, the switches are triggered with a delay to minimize the power required at one time (we minimize the recovery periods). See [Configuration](#select-the-driven-entity)
+> * **Release 3.1**: added detection of open windows/doors by temperature drop. This new function makes it possible to automatically stop a radiator when the temperature drops suddenly. See [Auto mode](#auto-mode)
+> * **Major release 3.0**: addition of thermostat equipment and associated sensors (binary and non-binary). Much closer to the Home Assistant philosophy, you now have direct access to the energy consumed by the radiator controlled by the thermostat and many other sensors that will be useful in your automations and dashboard.
+> * **release 2.3**: addition of the power and energy measurement of the radiator controlled by the thermostat.
+> * **release 2.2**: addition of a safety function allowing a radiator not to be left heating forever in the event of a thermometer failure
+> * **major release 2.0**: addition of the "over climate" thermostat allowing you to transform any thermostat into a Versatile Thermostat and add all the functions of the latter.

-Because this integration aims to command the heater considering the preset configured and the room temperature, those informations are mandatory.
+# Thanks for the beer [buymecoffee]: https://www.buymeacoffee.com/jmcollin78
+Many thanks to @salabur for the beer. It's very pleasing. (Vielen Dank an @salabur für das Bier. Es ist sehr erfreulich.)

-## Why another thermostat implementation ?
-For my personnal usage, I needed to add a couple of features and also to update the behavior that I implemented in my previous component "Awesome thermostat".
-This new component "Versatile thermostat" now manage the following use cases :
- Configuration through GUI using Config Entry flow,
- Explicitely define the temperature for all presets mode,
- Unset the preset mode when the temperature is manually defined on a thermostat,
- Turn off/on a thermostat when a door or windows is opened/closed after a certain delay,
- Set a preset when an activity is detected in a room, and another one after no activity has been detected for a defined time,
- Use a proportional algorithm with two function (see below),
- Add power management to avoid exceeding a defined total power. When max power is exceeded, a new 'power' preset is set on the climate entity. When power goes below the max, the previous preset is restored.
+# When to use / not use
+This thermostat can control 2 types of equipment:
+1. a heater that only works in on/off mode (named ```thermostat_over_switch```). The minimum configuration required to use this type of thermostat is:
+   has. equipment such as a radiator (a ```switch``` or equivalent),
+   b. a temperature probe for the room (or an input_number),
+   vs. an external temperature sensor (think about weather integration if you don't have one)
+2. another thermostat that has its own operating modes (named ```thermostat_over_climate```). For this type of thermostat, the minimum configuration requires:
+   has. equipment such as air conditioning which is controlled by its own ```climate``` type entity,
+   b. a temperature probe for the room (or an input_number),
+   vs. an external temperature sensor (think about weather integration if you don't have one)

-## How to install this incredible thermostat
+The ```thermostat_over_climate``` type allows you to add all the functionality provided by VersatileThermostat to your existing equipment. The climate VersatileThermostat entity will control your climate entity, turning it off if the windows are open, switching it to Eco mode if no one is present, etc. See [here](#why-a-new-implementation-of-the-thermostat). For this type of thermostat, any heating cycles are controlled by the underlying climate entity and not by the Versatile Thermostat itself.

-### HACS installation
+# Why another thermostat implementation ?
+
+
+This component named __Versatile thermostat__ manage the following use cases :
+- Configuration through standard integration GUI (using Config Entry flow),
+- Full uses of **presets mode**,
+- Unset the preset mode when the temperature is **manually defined** on a thermostat,
+- Turn off/on a thermostat when a **door or windows is opened/closed** after a certain delay,
+- Change preset when an **activity is detected** or not in a room for a defined time,
+- Use a **TPI (Time Proportional Interval) algorithm** thank's to [[Argonaute](https://forum.hacf.fr/u/argonaute/summary)] algorithm ,
+- Add **power shedding management** or regulation to avoid exceeding a defined total power. When max power is exceeded, a hidden 'power' preset is set on the climate entity. When power goes below the max, the previous preset is restored.
+- Add **home presence management**. This feature allows you to dynamically change the temperature of preset considering a occupancy sensor of your home.
+- Add **services to interact with the thermostat** from others integration: you can force the presence / un-presence using a service, and you can dynamically change the temperature of the presets and change dynamically the security parameters.
+- Add sensors to see the internal states of the thermostat

+### The sensor mode
+In sensor mode, you must fill in the following information:
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-window-sensor.png?raw=true)
+
+1. an entity ID of a **window/door sensor**. It should be a binary_sensor or an input_boolean. The state of the entity must be 'on' when the window is open or 'off' when it is closed
+2. a **delay in seconds** before any change. This allows a window to be opened quickly without stopping the heating.
+
+### Auto mode
+In auto mode, the configuration is as follows:
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-window-auto.png?raw=true)
+
+1. a detection threshold in degrees per minute. When the temperature drops below this threshold, the thermostat will turn off. The lower this value, the faster the detection will be (in return for a risk of false positives),
+2. an end of detection threshold in degrees per minute. When the temperature drop goes above this value, the thermostat will go back to the previous mode (mode and preset),
+3. maximum detection time. Beyond this time, the thermostat will return to its previous mode and preset even if the temperature continues to drop.
+
+To set the thresholds it is advisable to start with the reference values and adjust the detection thresholds. A few tries gave me the following values (for a desktop):
+- detection threshold: 0.05°C/min
+- non-detection threshold: 0 °C/min
+- maximum duration: 60 min.
+
+A new "slope" sensor has been added for all thermostats. It gives the slope of the temperature curve in °C/min (or °K/min). This slope is smoothed and filtered to avoid aberrant values from the thermometers which would interfere with the measurement.
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/temperature-slope.png?raw=true)
+
+To properly adjust it is advisable to display on the same historical graph the temperature curve and the slope of the curve (the "slope"):

+    2. If you don't have a window/door sensor in your room, just leave the sensor entity id blank,
+    3. **Only one mode is allowed**. You cannot configure a thermostat with a sensor and automatic detection. The 2 modes may contradict each other, it is not possible to have the 2 modes at the same time,

 What we need:
- a motion sensor. The entity id of a motion sensor. Motion sensor states should be 'on' (motion detected) or 'off' (no motion detected)
- a "motion delay" duration defining how many time we leave the temperature like in "motion" mode after the last motion is detected.
- a target "motion" preset. We will used the same temperature than this preset when an activity is detected.
- a target "no motion" preset. We will used the same temperature than this preset when no activity is detected.
+- a **motion sensor**. The entity id of a motion sensor. Motion sensor states should be 'on' (motion detected) or 'off' (no motion detected)

+- a **target "motion" preset**. We will used the temperature of this preset when an activity is detected.
+- a **target "no motion" preset**. We will used the temperature of this second preset when no activity is detected.

 So imagine we want to have the following behavior :

-## Algorithm
+## Configure the presence or occupancy
+If you choose the ```Presence management``` feature, this feature allows you to dynamically changes the temperature of all configured Versatile thermostat's presets when nobody is at home or when someone comes back home. For this, you have to configure the temperature that will be used for each preset when presence is off. When the occupancy sensor turns to off, those tempoeratures will be used. When it turns on again the "normal" temperature configured for the preset is used. See [preset management](#configure-the-preset-temperature).
+To configure presence fills this form:
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-presence.png?raw=true)
+
+For this you need to configure:
+1. A **occupancy sensor** which state should be 'on' or 'home' if someone is present or 'off' or 'not_home' else,
+2. The **temperature used in Eco** preset when absent,
+3. The **temperature used in Comfort** preset when absent,
+4. The **temperature used in Boost** preset when absent
+
+> ![Tip](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true)  _*Notes*_
+      1. the switch of temperature is immediate and is reflected on the front component. The calculation will take the new target temperature into account at the next cycle calculation,
+      2. you can use direct person.xxxx sensor or group of sensors of Home Assistant. The presence sensor handles ``on`` or ``home`` states as present and ``off`` or ``not_home`` state as absent.
+
+## Advanced configuration
+Those parameters allows to fine tune the thermostat.
+The advanced configuration form is the following:
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-advanced.png?raw=true)
+
+The first delay (minimal_activation_delay_sec) in sec in the minimum delay acceptable for turning on the heater. When calculation gives a power on delay below this value, the heater will stays off.
+
+The second delay (security_delay_min) is the maximal delay between two temperature measure before setting the preset to ``security`` and turning off the thermostat. If the temperature sensor is no more giving temperature measures, the thermostat and heater will turns off after this delay and the preset of the thermostat will be set to ``security``. This is useful to avoid overheating is the battery of your temperature sensor is too low.
+
+The third parameter (``security_min_on_percent``) is the minimum value of ``on_percent`` below which the security preset will not be activated. This parameter makes it possible not to put a thermostat in safety, if the controlled radiator does not heat sufficiently.
+Setting this parameter to ``0.00`` will trigger the security preset regardless of the last heating setpoint, conversely ``1.00`` will never trigger the security preset (which amounts to disabling the function).
+
+The fourth parameter (``security_default_on_percent``) is the ``on_percent`` value that will be used when the thermostat enters ``security`` mode. If you put ``0`` then the thermostat will be cut off when it goes into ``security`` mode, putting 0.2% for example allows you to keep a little heating (20% in this case), even in mode ``security``. It avoids finding your home totally frozen during a thermometer failure.
+
+See [example tuning](#examples-tuning) for common tuning examples
+
+>![Tip](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Notes*_
+    1. When the temperature sensor comes to life and returns the temperatures, the preset will be restored to its previous value,
+    3. Attention, two temperatures are needed: internal temperature and external temperature and each must give the temperature, otherwise the thermostat will be in "security" preset,
+    4. A service is available that allows you to set the 3 security parameters. This can be used to adapt the security function to your use.
+    5. For natural usage, the ``security_default_on_percent`` should be less than ``security_min_on_percent``,
+    6. When a ``thermostat_over_climate`` type thermostat goes into ``security`` mode it is turned off. The ``security_min_on_percent`` and ``security_default_on_percent`` parameters are then not used.
+
+# Examples tuning
+
+## Electrical heater
+- cycle: between 5 and 10 minutes,
+- minimal_activation_delay_sec: 30 seconds
+
+## Central heating (gaz or fuel heating system)
+- cycle: between 30 and 60 min,
+- minimal_activation_delay_sec: 300 seconds (because of the response time)
+
+## Temperature sensor will battery
+- security_delay_min: 60 min (because these sensors are lazy)
+- security_min_on_percent: 0.5 (50% - we go to the ``security`` preset if the radiator was heating more than 50% of the time)
+- security_default_on_percent: 0.1 (10% - in preset ``security``, we keep a heating background 20% of the time)
+
+These settings should be understood as follows:
+
+> If the thermometer no longer sends the temperature for 1 hour and the heating percentage (``on_percent``) was greater than 50%, then this heating percentage is reduced to 10%.
+
+It's up to you to adapt these settings to your case!
+
+What is important is not to take too many risks with these parameters: suppose you are away for a long period, that the batteries of your thermometer reach the end of their life, your radiator will heat up 10% of the time for the whole the duration of the outage.
+
+Versatile Thermostat allows you to be notified when an event of this type occurs. Set up the alerts that go well as soon as you use this thermostat. See (#notifications)

+## Reactive temperature sensor (on mains)

+- security_min_on_percent: 0.7 (70% - we go to the ``security`` preset if the radiator was heating more than 70% of the time)
+- security_default_on_percent: 0.25 (25% - in preset ``security``, we keep a heating background 25% of the time)
+
+## My preset configuration
+This is just an example of how I use the preset. It up to you to adapt to your configuration but it can be useful to understand how it works.

+
+# Algorithm
 This integration uses a proportional algorithm. A Proportional algorithm is useful to avoid the oscillation around the target temperature. This algorithm is based on a cycle which alternate heating and stop heating. The proportion of heating vs not heating is determined by the difference between the temperature and the target temperature. Bigger the difference is and bigger is the proportion of heating inside the cycle.
+
 This algorithm make the temperature converge and stop oscillating.

-Depending of your area and heater, the convergente temperature can be under the targeted temperature. So a bias parameter is available to fix this. To find the right value of biais, just set it to 0 (no biais), let the temperature converge and see if it is near the targeted temperature. If not adjust the biais. A good value is 0.25 with my accumulator radiator (which are long to heat but keeps the heat for a long time).
+## TPI algorithm
+The TPI algorithm consist in the calculation at each cycle of a percentage of On state vs Off state for the heater using the target temperature, the current temperature in the room and the current external temperature.

-A function parameter is available. Set it to "Linear" to have a linéar growth of temperature or set it to "Atan" to have a more aggressive curve to target temperature depending of your need.
+The percentage is calculated with this formula:

-### Some results
+    on_percent = coef_int * (target temperature - current temperature) + coef_ext * (target temperature - external temperature)
+    Then make 0 <= on_percent <= 1

-Convergence of temperature to target configured by preset:
-![image](https://github.com/jmcollin78/versatile_thermostat/blob/dev/images/results-1.png?raw=true)
+Defaults values for coef_int and coef_ext are respectively: ``0.6`` and ``0.01``. Those defaults values are suitable for a standard well isolated room.

-Cycle of on/off calculated by the integration:
-![image](https://github.com/jmcollin78/versatile_thermostat/blob/dev/images/results-2.png?raw=true)
+To tune those coefficients keep in mind that:
+1. **if target temperature is not reach** after stable situation, you have to augment the ``coef_ext`` (the ``on_percent`` is too low),
+2. **if target temperature is exceeded** after stable situation, you have to decrease the ``coef_ext`` (the ``on_percent`` is too high),
+3. **if reaching the target temperature is too slow**, you can increase the ``coef_int`` to give more power to the heater,
+4. **if reaching the target temperature is too fast and some oscillations appears** around the target, you can decrease the ``coef_int`` to give less power to the heater
+
+See some situations at [examples](#some-results).
+
+# Sensors
+
+With the thermostat are available sensors that allow you to view the alerts and the internal status of the thermostat. They are available in the entities of the device associated with the thermostat:
+
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/thermostat-sensors.png?raw=true)
+
+In order, there are:
+1. the main climate thermostat command entity,
+2. the energy consumed by the thermostat (value which continuously increases),
+3. the time of receipt of the last outside temperature,
+4. the time of receipt of the last indoor temperature,
+5. the average power of the device over the cycle (for TPIs only),
+6. the time spent in the off state in the cycle (TPI only),
+7. the time spent in the on state in the cycle (TPI only),
+8. load shedding status,
+9. cycle power percentage (TPI only),
+10. presence status (if presence management is configured),
+11. security status,
+12. opening status (if opening management is configured),
+13. motion status (if motion management is configured)
+
+To color the sensors, add these lines and customize them as needed, in your configuration.yaml:
+
+```
+frontend:
+  themes:
+    versatile_thermostat_theme:
+      state-binary_sensor-safety-on-color: "#FF0B0B"

+
+# Services
+
+This custom implementation offers some specific services to facilitate integration with others Home Assisstant components.
+
+## Force the presence / occupancy
+This service allows you to force the presence status independantly of the presence sensor. This can be useful if you want to manage the presence through a service and not through a sensor. For example, you could use your alarm to force the absence when it is switched on.
+
+The code to call this service is the following:
+```
+service: versatile_thermostat.set_presence
+data:
+    presence: "off"
+target:
+    entity_id: climate.my_thermostat
+```
+
+## Change the temperature of presets
+This services is useful if you want to dynamically change the preset temperature. Instead of changing preset, some use-case need to change the temperature of the preset. So you can keep the Scheduler unchanged to manage the preset and adjust the temperature of the preset.
+If the changed preset is currently selectionned, the modification of the target temperature is immediate and will be taken into account at the next calculation cycle.
+
+You can change the one or the both temperature (when present or when absent) of each preset.
+
+Use the following code the set the temperature of the preset:
+```
+service: versatile_thermostat.set_preset_temperature
+data:
+    preset: boost
+    temperature: 17.8
+    temperature_away: 15
+target:
+    entity_id: climate.my_thermostat
+```
+
+> ![Tip](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true)  _*Notes*_
+    - after a restart the preset are resetted to the configured temperature. If you want your change to be permanent you should modify the temperature preset into the confguration of the integration.
+
+## Change security settings
+This service is used to dynamically modify the security parameters described here [Advanced configuration](#configuration-avanced).
+If the thermostat is in ``security`` mode the new settings are applied immediately.
+
+To change the security settings use the following code:
+```
+service : thermostat_polyvalent.set_security
+date:
+    min_on_percent: "0.5"
+    default_on_percent: "0.1"
+    delay_min: 60
+target:
+    entity_id : climate.my_thermostat
+```
+
+# Notifications
+Significant thermostat events are notified via the message bus.
+The notified events are as follows:
+
+- ``versatile_thermostat_security_event``: a thermostat enters or exits the ``security`` preset
+- ``versatile_thermostat_power_event``: a thermostat enters or exits the ``power`` preset
+- ``versatile_thermostat_temperature_event``: one or both temperature measurements of a thermostat have not been updated for more than ``security_delay_min`` minutes
+- ``versatile_thermostat_hvac_mode_event``: the thermostat is on or off. This event is also broadcast when the thermostat starts up
+- ``versatile_thermostat_preset_event``: a new preset is selected on the thermostat. This event is also broadcast when the thermostat starts up
+
+If you have followed correctly, when a thermostat goes into safety mode, 3 events are triggered:
+1. ``versatile_thermostat_temperature_event`` to indicate that a thermometer has become unresponsive,
+2. ``versatile_thermostat_preset_event`` to indicate the switch to ```security``` preset,
+3. ``versatile_thermostat_hvac_mode_event`` to indicate the possible extinction of the thermostat
+
+Each event carries the key values of the event (temperatures, current preset, current power, etc.) as well as the states of the thermostat.
+
+You can very easily capture its events in an automation, for example to notify users.
+
+# Custom attributes
+
+To tune the algorithm you have access to all context seen and calculted by the thermostat through dedicated attributes. You can see (and use) those attributes in the "Development tools / states" HMI of HA. Enter your thermostat and you will see something like this:
+![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/dev-tools-climate.png?raw=true)

+**Fine tuned thermostat**
+Thank's [impuR_Shozz](https://forum.hacf.fr/u/impur_shozz/summary) !
+We can see stability around the target temperature (consigne) and when at target the on_percent (puissance) is near 0.3 which seems a very good value.
