+
+## Entités de température pour les pre-réglages
+Les températures des presets sont maintenant directement acessibles sous la forme d'entités reliés au VTherm.
+Exemple :
+
+![Entités température](images/temp-entities-1.png)
+
+Les entités Boost, Confort, Eco et Hors-gel permettent de régler directement les températures de ces présets sans avoir à reconfigurer le VTHerm dans les écrans de configuration.
+Ces modifications sont persistentent à un redémarrage et sont prises en compte immédiatement par le VTherm.
+
+En fonction des fonctions activées, la liste des températures peut être plus ou moins complète :
+1. Si la gestion de présence est activée, les presets en cas d'absence sont créés. Ils sont suffixés par 'abs' pour absence,
+2. Si la gestion de la climatisation (Mode AC) est activé, les presets en mode clim sont créés. Ils sont suffixés par 'clim' pour climatisation. Seul le preset Hors gel n'a pas d'équivalent en mode clim,
+3. Les différentes combinaison absent et clim peuvent être créés en fonction de la configuration du VTherm
+
+Si un VTherm utilise les preset de la configuration centrale, ces entités ne sont pas créées, car les températures des presets sont gérés par la configuration centrale.
+
+### Dans le cas d'une configuration centrale
+Si vous avez configuré une configuration centrale, celle-ci possède aussi ses propres presets qui répondent au même règles qu'énoncées ci-dessus.
+Exemple d'une configuration centrale avec gestion de présence et mode AC (climatisation) :
+
+![Entités température](images/temp-entities-2.png)
+
+Dans le cas d'un changement d'une température de la configuration centrale, tous les VTherm qui utilisent ce preset sont immédiatement mis à jour.
+
+## Refonte du menu de configuration
+Le menu de configuration a été totalement revu. Il s'adapte dynamiquement aux choix de l'utilisateur et permet d'accéder directement aux réglages de la fonction voulue sans avoir à dérouler tous le tunnel de configuration.
+

+
+Puis, vous accédez maintenant au menu de configuration suivant :
+

+
+Vous noterez l'option de menu nommée `Fonctions` qui permet de choisir quelles fonctions vont être implémentées pour ce VTherm :
+
+![VTherm fonctions](images/config-features.png)

+En fonction de vos choix, le menu principal s'adaptera pour ajouter les options nécessaires.
+
+Exemple de menu avec toutes les fonctions cochées :
+
+![VTherm menu](images/config-menu-all-options.png)
+Vous pouvez constater que les options 'Détection des ouvertures', 'Détection de mouvement', 'Gestion de la puissance' et 'Gestion de présence' ont été ajoutées. Vous pouvez alors les configurer.
+
+### Les options de menu 'Configuration incomplète' et 'Finaliser'
+
+La dernière option du menu est spéciale. Elle permet de valider la création du VTherm lorsque toutes les fonctions ont été correctement configurées.
+Si l'une options n'est pas correctement configurée, la dernière option est la suivante :

 Pour que les modifications soient prises en compte, il faut soit **relancer totalement Home Assistant** soit juste l'intégration Versatile Thermostat (Outils de dev / Yaml / rechargement de la configuration / Versatile Thermostat).

+#### Compensation de la température interne
+Quelque fois, il arrive que le thermomètre interne du sous-jacent (TRV, climatisation, ...) soit tellement faux que l' auto-régulation ne suffise pas à réguler.
+Cela arrive lorsque le thermomètre interne est trop près de la source de chaleur. La température interne monte alors beaucoup plus vite que la température de la pièce, ce qui génère des défauts dans la régulation.
+Exemple :
+1. la température de la pièce est 18°, la consigne est à 20°,
+2. la température interne de l'équipement est de 22°,
+3. si VTherm envoie 21° comme consigne (= 20° + 1° d'auto-regulation), alors l'équipement ne chauffera pas car sa température interne (22°) est au-dessus de la consigne (21°)
+
+Pour palier à ça, une nouvelle option facultative a été ajoutée en version 5.4 : ![Utilisation de la température interne](images/config-use-internal-temp.png)
+
+Lorsqu'elle est activée, cette fonction ajoutera l'écart entre la température interne et la température de la pièce à la consigne pour forcer le chauffage.
+Dans l'exemple ci-dessus, l'écart est de +4° (22° - 18°), donc VTherm enverra 25° (21°+4°) à l'équipement le forçant ainsi à chauffer.
+
+Cet écart est calculé pour chaque sous-jacent car chacun à sa propre température interne. Pensez à un VTherm qui serait relié à 3 TRV chacun avec sa température interne par exemple.
+
+On obtient alors une auto-régulation bien plus efficace qui évite l'eccueil des gros écarts de température interne défaillante.
+
+#### Synthèse de l'algorithme d'auto-régulation
+L'algorithme d'auto-régulation peut être synthétisé comme suit:
+
+1. initialiser la température cible comme la consigne du VTherm,
+1. Si l'auto-régulation est activée,
+   1. calcule de la température régulée (valable pour un VTherm),
+   2. prendre cette température comme cible,
+2. Pour chaque sous-jacent du VTherm,
+     1. Si "utiliser la température interne" est cochée,
+          1. calcule de l'écart (trv internal temp - room temp),
+     2. ajout de l'écart à la température cible,
+     3. envoie de la température cible ( = temp regulee + (temp interne - temp pièce)) au sous-jacent
+
+

 #### Le mode auto-fan

 Une fois l'écart de température redevenu faible, la ventilation se mettra dans un mode "normal" qui dépend de votre équipement à savoir (dans l'ordre) : `Silence (mute)`, `Auto (auto)`, `Faible (low)`. La première valeur qui est possible pour votre équipement sera choisie.

+#### Le démarrage / arrêt automatique
+Cette fonction a été introduite en 6.5.0. Elle permet d'autoriser VTherm a stopper un équipement qui n'a pas besoin d'être allumé et de le redémarrer lorsque les conditions le réclame. Cette fonction est munie de 3 réglages qui permettent d'arrêter / relancer plus ou moins rapidement l'équipement.
+
+Pour l'utiliser, vous devez :
+1. Ajouter la fonction `Avec démmarrage et extinction automatique` dans le menu 'Fonctions',
+2. Paramétrer le niveau de détection dans l'option 'Allumage/extinction automatique' qui s'affiche lorsque la fonction a été activée. Vous choisissez le niveau de détection entre 'Lent', 'Moyen' et 'Rapide'. Les arrêts/relances seront plus nombreux avec le niveau 'Rapide'.
+
+Une fois paramétré, vous aurez maintenant une nouvelle entité de type `switch` qui vous permet d'autoriser ou non l'arrêt/relance automatique sans toucher à la configuration. Cette entité est disponible sur l'appareil VTherm et se nomme `switch.<name>_enable_auto_start_stop`. Cochez la pour autoriser le démarrage et extinction automatique.

+## Le contrôle centralisé
+
+Depuis la release 5.2, si vous avez défini une configuration centralisée, vous avez une nouvelle entité nommée `select.central_mode` qui permet de piloter tous les VTherms avec une seule action. Pour qu'un VTherm soit contrôlable de façon centralisée, il faut que son attribut de configuration nommé `use_central_mode` soit vrai.
+
+Cette entité se présente sous la forme d'une liste de choix qui contient les choix suivants :
+1. `Auto` : le mode 'normal' dans lequel chaque VTherm se comporte comme dans les versions précédentes,
+2. `Stooped` : tous les VTherms sont mis à l'arrêt (`hvac_off`),
+3. `Heat only` : tous les VTherms sont mis en mode chauffage lorsque ce mode est supporté par le VTherm, sinon il est stoppé,
+3. `Cool only` : tous les VTherms sont mis en mode climatisation lorsque ce mode est supporté par le VTherm, sinon il est stoppé,
+4. `Frost protection` : tous les VTherms sont mis en preset hors-gel lorsque ce preset est supporté par le VTherm, sinon il est stoppé.
+
+Il est donc possible de contrôler tous les VTherms (que ceux que l'on désigne explicitement) avec un seul contrôle.
+Exemple de rendu :
+
+![central_mode](images/central_mode.png)
+
+## Le contrôle d'une chaudière centrale
+
+Depuis la release 5.3, vous avez la possibilité de contrôler une chaudière centralisée. A partir du moment où il est possible de déclencher ou stopper cette chaudière depuis Home Assistant, alors Versatile Thermostat va pouvoir la commander directement.
+
+Le principe mis en place est globalement le suivant :
+1. une nouvelle entité de type `binary_sensor` et nommée par défaut `binary_sensor.central_boiler` est ajoutée,
+2. dans la configuration des VTherms vous indiquez si le VTherm doit contrôler la chaudière. En effet, dans une installation hétérogène, certains VTherm doivent commander la chaudière et d'autres non. Vous devez donc indiquer dans chaque configuration de VTherm si il contrôle la chaudière ou pas,
+3. le `binary_sensor.central_boiler` écoute les changements d'états des équipements des VTherm marqués comme contrôlant la chaudière,
+4. dès que le nombre d'équipements pilotés par le VTherm demandant du chauffage (ie son `hvac_action` passe à `Heating`) dépasse un seuil paramétrable, alors le `binary_sensor.central_boiler` passe à `on` et **si un service d'activation a été configuré, alors ce service est appelé**,
+5. si le nombre d'équipements nécessitant du chauffage repasse en dessous du seuil, alors le `binary_sensor.central_boiler` passe à `off` et si **un service de désactivation a été configuré, alors ce service est appelé**,
+6. vous avez accès à deux entités :
+   - une de type `number` nommé par défaut `number.boiler_activation_threshold`, donne le seuil de déclenchement. Ce seuil est en nombre d'équipements (radiateurs) qui demande du chauffage.
+   - une de type `sensor` nommé par défaut `sensor.nb_device_active_for_boiler`, donne le nombre d'équipements qui demande du chauffage. Par exemple, un VTherm ayant 4 vannes dont 3 demandes du chauffage fera passé ce capteur à 3. Seuls les équipements des VTherms qui sont marqués pour contrôler la chaudière centrale sont comptabilisés.
+
+Vous avez donc en permanence, les informations qui permettent de piloter et régler le déclenchement de la chaudière.
+
+Toutes ces entités sont rattachés au service de configuration centrale :
+![Les entités pilotant la chaudière](images/entitites-central-boiler.png)
+
+### Configuration
+Pour configurer cette fonction, vous devez avoir une configuration centralisée (cf. [Configuration](#configuration)) et cochez la case 'Ajouter une chuadière centrale' :
+
+![Ajout d'une chaudière centrale](images/config-central-boiler-1.png)
+
+Sur la page suivante vous pouvez donner la configuration des services à appeler lors de l'allumage / extinction de la chaudière :
+
+![Ajout d'une chaudière centrale](images/config-central-boiler-2.png)
+
+Les services se configurent comme indiqués dans la page :
+1. le format général est `entity_id/service_id[/attribut:valeur]` (où `/attribut:valeur` est facultatif),
+2. `entity_id` est le nom de l'entité qui commande la chaudière sous la forme `domain.entity_name`. Par exemple: `switch.chaudiere` pour les chaudière commandée par un switch ou `climate.chaudière` pour une chaudière commandée par un thermostat ou tout autre entité qui permet le contrôle de la chaudière (il n'y a pas de limitation).  On peut aussi commuter des entrées (`helpers`) comme des `input_boolean` ou `input_number`.
+3. `service_id` est le nom du service à appeler sous la forme `domain.service_name`. Par exemple: `switch.turn_on`, `switch.turn_off`, `climate.set_temperature`, `climate.set_hvac_mode` sont des exemples valides.
+4. pour certain service vous aurez besoin d'un paramètre. Cela peut être le 'Mode CVC' `climate.set_hvac_mode` ou la température cible pour `climate.set_temperature`. Ce paramètre doit être configuré sous la forme `attribut:valeur` en fin de chaine.
+
+Exemples (à ajuster à votre cas) :
+- `climate.chaudiere/climate.set_hvac_mode/hvac_mode:heat` : pour allumer le thermostat de la chaudière en mode chauffage,
+- `climate.chaudiere/climate.set_hvac_mode/hvac_mode:off` : pour stopper le thermostat de la chaudière,
+- `switch.pompe_chaudiere/switch.turn_on` : pour allumer le swicth qui alimente la pompe de la chaudière,
+- `switch.pompe_chaudiere/switch.turn_off` : pour allumer le swicth qui alimente la pompe de la chaudière,
+- ...
+
+### Comment trouver le bon service ?
+Pour trouver le services a utiliser, le mieux est d'aller dans "Outils de développement / Services", chercher le service a appelé, l'entité à commander et l'éventuel paramètre à donner.
+Cliquez sur 'Appeler le service'. Si votre chaudière s'allume vous avez la bonne configuration. Passez alors en mode Yaml et recopiez les paramètres.
+
+Exemple:
+
+Sous "Outils de développement / Service" :
+
+![Configuration du service](images/dev-tools-turnon-boiler-1.png)
+
+En mode yaml :
+
+![Configuration du service](images/dev-tools-turnon-boiler-2.png)
+
+Le service à configurer est alors le suivant: `climate.empty_thermostast/climate.set_hvac_mode/hvac_mode:heat` (notez la suppression du blanc dans `hvac_mode:heat`)
+
+Faite alors de même pour le service d'extinction et vous êtes parés.
+
+### Les évènements
+
+A chaque allumage ou extinction réussie de la chaudière un évènement est envoyé par Versatile Thermostat. Il peut avantageusement être capté par une automatisation, par exemple pour notifier un changement.
+Les évènements ressemblent à ça :
+
+Un évènement d'allumage :

+
+### Avertissement
+
+> ![Astuce](images/tips.png) _*Notes*_
+> Le contrôle par du logiciel ou du matériel de type domotique d'une chaudière centrale peut induire des risques pour son bon fonctionnement. Assurez-vous avant d'utiliser ces fonctions, que votre chaudière possède bien des fonctions de sécurité et que celles-ci fonctionnent. Allumer une chaudière si tous les robinets sont fermés peut générer de la sur-pression par exemple.

 ## Seul le premier radiateur chauffe

 En mode `over_switch` si plusieurs radiateurs sont configurés pour un même VTherm, l'alllumage va se faire de façon séquentiel pour lisser au plus possible les pics de consommation.

+### Type `over_switch` ou `over_valve`
+Avec un VTherm de type `over_switch` ou `over_valve`, ce défaut montre juste que les paramètres de l'algorithme TPI sont mal réglés. Voir [Algorithme TPI](#algorithme-tpi) pour optimiser les réglages.
+
+### Type `over_climate`
+Avec un VTherm de type `over_climate`, la régulation est faite par le `climate` sous-jacent directement et VTherm se contente de lui transmettre les consignes. Donc si le radiateur chauffe alors que la température de consigne est dépassée, c'est certainement que sa mesure de température interne est biaisée. Ca arrive très souvent avec les TRV et les clims réversibles qui ont un capteur de température interne, soit trop près de l'élément de chauffe (donc trop froid l'hiver).
+
+Exemple de discussion autour de ces sujets: [#348](https://github.com/jmcollin78/versatile_thermostat/issues/348), [#316](https://github.com/jmcollin78/versatile_thermostat/issues/316), [#312](https://github.com/jmcollin78/versatile_thermostat/discussions/312), [#278](https://github.com/jmcollin78/versatile_thermostat/discussions/278)
+
+Pour s'en sortir, VTherm est équipé d'une fonction nommée auto-régulation qui permet d'adapter la consigne envoyée au sous-jacent jusqu'à ce que la consigne soit respectée. Cette fonction permet de compenser le biais de mesure des thermomètres internes. Si le biais est important la régulation doit être importante.

 ## Pourquoi mon Versatile Thermostat se met en Securite ?
-Le mode sécurité n'est possible que sur les VTherm `over_switch` et `over_valve`. Il survient lorsqu'un des 2 thermomètres qui donne la température de la pièce ou la température extérieure n'a pas envoyé de valeur depuis plus de `security_delay_min` minutes et que le radiateur chauffait à au moins `security_min_on_percent`.
+Le mode sécurité est possible sur tous les types de VTherm . Il survient lorsqu'un des 2 thermomètres qui donne la température de la pièce ou la température extérieure n'a pas envoyé de valeur depuis plus de `security_delay_min` minutes et que le radiateur chauffait à au moins `security_min_on_percent`.

 Comme l'algorithme est basé sur les mesures de température, si elles ne sont plus reçues par le VTherm, il y a un risque de surchauffe et d'incendie. Pour éviter ça, lorsque les conditions rappelées ci-dessus sont détectées, la chauffe est limité au paramètre `security_default_on_percent`. Cette valeur doit donc être raisonnablement faible (10% est une bonne valeur). Elle permet d'éviter un incendie tout en évitant de couper totalement le radiateur (risque de gel).

 3. Certains capteurs de température, n'envoie pas de mesure si la température n'a pas changée. Donc en cas de température très stable pendant longtemps, le mode sécurité peut se déclencher. Ce n'est pas très grave puisqu'il s'enlève dès que le VTherm reçoit à nouveau une température. Sur certain thermomètre (TuYA par exemple), on peut forcer le délai max entre 2 mesures.
