 Self-regulation consists of forcing the equipment to go further by forcing its set temperature regularly. Its consumption can therefore be increased, as well as its wear.
 
-#### Self-regulation in Expert mode
-
-In **Expert** mode you can finely adjust the auto-regulation parameters to achieve your objectives and optimize as best as possible. The algorithm calculates the difference between the setpoint and the actual temperature of the room. This discrepancy is called error.
-The adjustable parameters are as follows:
-1. `kp`: the factor applied to the raw error,
-2. `ki`: the factor applied to the accumulation of errors,
-3. `k_ext`: the factor applied to the difference between the interior temperature and the exterior temperature,
-4. `offset_max`: the maximum correction (offset) that the regulation can apply,
-5. `stabilization_threshold`: a stabilization threshold which, when reached by the error, resets the accumulation of errors to 0,
-6. `accumulated_error_threshold`: the maximum for error accumulation.
-
-For tuning, these observations must be taken into account:
-1. `kp * error` will give the offset linked to the raw error. This offset is directly proportional to the error and will be 0 when the target is reached,
-2. the accumulation of the error makes it possible to correct the stabilization of the curve while there remains an error. The error accumulates and the offset therefore gradually increases which should eventually stabilize at the target temperature. For this fundamental parameter to have an effect it must not be too small. An average value is 30
-3. `ki * accumulated_error_threshold` will give the maximum offset linked to the accumulation of the error,
-4. `k_ext` allows a correction to be applied immediately (without waiting for errors to accumulate) when the outside temperature is very different from the target temperature. If the stabilization is done too high when the temperature differences are significant, it is because this parameter is too high. It should be possible to cancel completely to let the first 2 offsets take place
-
-The pre-programmed values are as follows:
-
-Slow régulation :
-
-    kp: 0.2  # 20% of the current internal regulation offset are caused by the current difference of target temperature and room temperature
-    ki: 0.8 / 288.0  # 80% of the current internal regulation offset are caused by the average offset of the past 24 hours
-    k_ext: 1.0 / 25.0  # this will add 1°C to the offset when it's 25°C colder outdoor than indoor
-    offset_max: 2.0  # limit to a final offset of -2°C to +2°C
-    stabilization_threshold: 0.0  # this needs to be disabled as otherwise the long term accumulated error will always be reset when the temp briefly crosses from/to below/above the target
-    accumulated_error_threshold: 2.0 * 288  # this allows up to 2°C long term offset in both directions

 #### Internal temperature compensation
-Sometimes, it happens that the internal thermometer of the underlying (TRV, air conditioning, etc.) is so wrong that self-regulation is not enough to regulate.
-This happens when the internal thermometer is too close to the heat source. The internal temperature then rises much faster than the room temperature, which generates faults in the regulation.
-Example :
-1. the room temperature is 18°, the setpoint is 20°,
-2. the internal temperature of the equipment is 22°,
-3. if VTherm sends 21° as setpoint (= 20° + 1° auto-regulation), then the equipment will not heat because its internal temperature (22°) is above the setpoint (21°)
+Sometimes, a device’s internal temperature sensor (like in a TRV or AC) can give inaccurate readings, especially if it’s too close to a heat source. This can cause the device to stop heating too soon.
+For example:
+1. target temperature: 20 °C, room temperature: 18 °C,
+2. device’s internal sensor: 22 °C
+3. If the target temperature is increased to 21 °C, the device won’t heat because it thinks it’s already warm (internal temperature is 22°C).
 
-To overcome this, a new optional option was added in version 5.4: ![Use of internal temperature](images/config-use-internal-temp.png)
+The Adjust Setpoint for Room vs. TRV Temperature feature fixes this by adding the temperature difference between the room and the device’s internal reading to the target. In this case, VTherm would adjust the target to 25°C (21°C + 4°C difference), forcing the device to continue heating.
 
-When enabled, this function will add the difference between the internal temperature and the room temperature to the setpoint to force heating.
-In the example above, the difference is +4° (22° - 18°), so VTherm will send 25° (21°+4°) to the equipment forcing it to heat up.
-
-This difference is calculated for each underlying because each has its own internal temperature. Think of a VTherm which would be connected to 3 TRVs each with its internal temperature for example.
-
-We then obtain much more effective self-regulation which avoids the pitfall of large variations in faulty internal temperature.
+This adjustment is specific to each device, making the heating system more accurate and avoiding issues from faulty sensor readings.

+#### Automatic start/stop
+This function was introduced in 6.5.0. It allows VTherm to stop equipment that does not need to be turned on and to restart it when conditions require it. This function has 3 settings that allow the equipment to be stopped/restarted more or less quickly.
+
+To use it, you must:
+1. Add the `Use the auto start and stop feature` function in the 'Features' menu,
+2. Set the detection level in the `Auto start and stop` option that is displayed when the function has been activated. You choose the detection level between 'Slow', 'Medium' and 'Fast'. The 'Fast' level will result in more shutdowns/restarts.
+
+Once configured, you will now have a new entity of type `switch` that allows you to authorize or not the automatic shutdown/restart without touching the configuration. This entity is available on the VTherm device and is called `switch.<name>_enable_auto_start_stop`. Check it to authorize the automatic startup and shutdown.

+## Expert Mode Settings
+
+Expert Mode settings refer to Settings made in the Home Assistant `configuration.yaml` file under the `versatile_thermostat` section. You might have to add this section by yourself to the `configuration.yaml` file.
+
+These settings are meant to be used only in **specific niche cases and with careful considerations**.
+
+
+The following sections describe the available export mode settings in detail with examples on how to configure them. Be aware that these settings require a **complete restart** of Home Assistant or a **reload of Versatile Thermostat integration** (Dev tools / Yaml / reloading the configuration / Versatile Thermostat) to take effect.
+
+
+### Self-regulation in Expert mode
+
+In **Expert** mode you can finely adjust the auto-regulation parameters to achieve your objectives and optimize as best as possible. The algorithm calculates the difference between the setpoint and the actual temperature of the room. This discrepancy is called error.
+The adjustable parameters are as follows:
+1. `kp`: the factor applied to the raw error,
+2. `ki`: the factor applied to the accumulation of errors,
+3. `k_ext`: the factor applied to the difference between the interior temperature and the exterior temperature,
+4. `offset_max`: the maximum correction (offset) that the regulation can apply,
+5. `stabilization_threshold`: a stabilization threshold which, when reached by the error, resets the accumulation of errors to 0,
+6. `accumulated_error_threshold`: the maximum for error accumulation.
+
+For tuning, these observations must be taken into account:
+1. `kp * error` will give the offset linked to the raw error. This offset is directly proportional to the error and will be 0 when the target is reached,
+2. the accumulation of the error makes it possible to correct the stabilization of the curve while there remains an error. The error accumulates and the offset therefore gradually increases which should eventually stabilize at the target temperature. For this fundamental parameter to have an effect it must not be too small. An average value is 30
+3. `ki * accumulated_error_threshold` will give the maximum offset linked to the accumulation of the error,
+4. `k_ext` allows a correction to be applied immediately (without waiting for errors to accumulate) when the outside temperature is very different from the target temperature. If the stabilization is done too high when the temperature differences are significant, it is because this parameter is too high. It should be possible to cancel completely to let the first 2 offsets take place
+
+The pre-programmed values are as follows:
+
+Slow régulation :
+
+    kp: 0.2  # 20% of the current internal regulation offset are caused by the current difference of target temperature and room temperature
+    ki: 0.8 / 288.0  # 80% of the current internal regulation offset are caused by the average offset of the past 24 hours
+    k_ext: 1.0 / 25.0  # this will add 1°C to the offset when it's 25°C colder outdoor than indoor
+    offset_max: 2.0  # limit to a final offset of -2°C to +2°C
+    stabilization_threshold: 0.0  # this needs to be disabled as otherwise the long term accumulated error will always be reset when the temp briefly crosses from/to below/above the target
+    accumulated_error_threshold: 2.0 * 288  # this allows up to 2°C long term offset in both directions
+
+Light régulation :
+
+    kp: 0.2
+    ki: 0.05
+    k_ext: 0.05
+    offset_max: 1.5
+    stabilization_threshold: 0.1
+    accumulated_error_threshold: 10
+
+Medium régulation :
+
+    kp: 0.3
+    ki: 0.05
+    k_ext: 0.1
+    offset_max: 2
+    stabilization_threshold: 0.1
+    accumulated_error_threshold: 20
+
+Strong régulation :
+
+    """Strong parameters for regulation
+    A set of parameters which doesn't take into account the external temp
+    and concentrate to internal temp error + accumulated error.
+    This should work for cold external conditions which else generates
+    high external_offset"""
+
+    kp: 0.4
+    ki: 0.08
+    k_ext: 0.0
+    offset_max: 5
+    stabilization_threshold: 0.1
+    accumulated_error_threshold: 50
+
+To use Expert mode you must declare the values you want to use for each of these parameters in your `configuration.yaml` in the following form:
+```
+versatile_thermostat:
+     auto_regulation_expert:
+         kp: 0.4
+         ki: 0.08
+         k_ext: 0.0
+         offset_max: 5
+         stabilization_threshold: 0.1
+         accumulated_error_threshold: 50
+```
+and of course, configure the VTherm's self-regulation mode in **Expert** mode. All VTherms in Expert mode will use these same settings.
+
+For the changes to be taken into account, you must either **completely restart Home Assistant** or just the **Versatile Thermostat integration** (Dev tools / Yaml / reloading the configuration / Versatile Thermostat).
+
+
+### On Time Clamping (max_on_percent)
+
+
+The calculated on time percent can be limited to a maximum percentage of the cycle duration. This setting has to be made in expert mode and will be used for all Versatile Thermostats.
+
+```
+versatile_thermostat:
+    max_on_percent: 0.8
+```
+
+The example above limits the maximum ON time to 80% (0.8) of the cycle length. If the cycle length is for example 600 seconds (10min), the maximum ON time will be limited to 480 seconds (8min). The remaining 120 seconds of the cycle will always remain in the OFF state.
+
+There are three debug attributes of interest regarding this feature:
+
+* `max_on_percent` # clamping setting as configured in expert mode
+* `calculated_on_percent` # calculated on percent without clamping applied
+* `on_percent` # used on percent with clamping applied

 ## Why does my Versatile Thermostat go into Safety?
 
-Safety mode is only possible on VTherm `over_switch` and `over_valve`. It occurs when one of the 2 thermometers which gives the room temperature or the outside temperature has not sent a value for more than `security_delay_min` minutes and the radiator was heating at least `security_min_on_percent`.
+Safety mode is possible on all VTherm's type. It occurs when one of the 2 thermometers which gives the room temperature or the outside temperature has not sent a value for more than `security_delay_min` minutes and the radiator was heating at least `security_min_on_percent`.
 
 As the algorithm is based on temperature measurements, if they are no longer received by the VTherm, there is a risk of overheating and fire. To avoid this, when the conditions mentioned above are detected, heating is limited to the `security_default_on_percent` parameter. This value must therefore be reasonably low. It helps prevent a fire while avoiding completely cutting off the radiator (risk of freezing).

+## Bien mieux avec le Versatile Thermostat UI Card
+Une carte spéciale pour le Versatile Thermostat a été développée (sur la base du Better Thermostat). Elle est dispo ici [Versatile Thermostat UI Card](https://github.com/jmcollin78/versatile-thermostat-ui-card) et propose une vision moderne de tous les status du VTherm :
+
+![image](https://github.com/jmcollin78/versatile-thermostat-ui-card/blob/master/assets/1.png?raw=true)
+
+## 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 Versatile Thermostat :
+
+À partir d'ici, je suppose que vous avez installé Versatile 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](images/simple-thermostat.png)
+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](images/custom-css-thermostat.png)
+
+## Toujours mieux avec Plotly pour régler votre thermostat
+Vous pouvez obtenir une courbe comme celle présentée dans [some results](#some-results) avec une sorte de configuration de graphique Plotly uniquement en utilisant les attributs personnalisés du thermostat décrits [ici](#custom-attributes) :
+
+Remplacez les valeurs entre [[ ]] par les votres.

+## 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).

+
+## L'algorithme TPI
+
+### Configurez les coefficients de l'algorithme TPI
+
+Si vous avez choisi un thermostat de type ```over_switch``` ou  ```over_valve``` ou `over_climate` avec l'auto-régulation `Controle direct de la vanne` et que vous sélectionnez l'option "TPI" vous menu, vous arriverez sur cette page :
+
+![image](images/config-tpi.png)
+
+Vous devez donner :
+1. le coefficient coef_int de l'algorithme TPI,
+2. le coefficient coef_ext de l'algorithme TPI
+
+
+### Principe
+
+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. Cet algorithme n'est donc valable que pour les Versatile Thermostat qui régulent : `over_switch` et `over_valve`.
+
+Le pourcentage est calculé avec cette formule :
+
+    on_percent = coef_int * (température cible - température actuelle) + coef_ext * (température cible - température extérieure)
+    Ensuite, l'algo fait en sorte que 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.
+
+En type `over_valve` le `on_percent` est ramené à une valeur entre 0 et 100% et sert directement à commander l'ouverture de la vanne.
+
+## L'algorithme d'auto-régulation (sans contrôle de la vanne)
+
+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 la compensation (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
+
+## L'algorithme de la fonction d'auto-start/stop
+
+L'algorithme utilisé dans la fonction d'auto-start/stop est le suivant :
+1. if enable aut-start/stop is off, stop here.
+2. If VTherm is on and in heating mode, when error_accumulated is < -error_threshold -> turn off and save hvac mode,
+3. If VTherm is on and in Cooling mode, when error_accumulated is > error_threshold -> turn off and save hvac mode,
+4. If VTherm is off and saved hvac mode is Heating and current_temperature + slope x dt <= target_temperature then turn on and set havc mode to the saved hvac_mode,
+5. If VTherm is off and saved hvac mode is Cooling and current_temperature + slope x dt >= target_temperature then turn on and set havc mode to the saved hvac_mode
+6. error_threshold is set to respectively 10 (° * min) in slow, 5 in medium and 2 in fast.
+
+dt is set to respectively 30 min in slow, 15 min in medium and 7 min in fast detection level.
+
+La fonction est décrite dans le détail [ici](https://github.com/jmcollin78/versatile_thermostat/issues/585).

+# Choix des attributs de base
+
+Choisisez le menu "Principaux attributs".
+
+![image](images/config-main.png)
+
+Donnez les principaux attributs obligatoires. Ces attributs sont communs à tous les VTherms :
+1. un nom (sera le nom de l'intégration et aussi le nom de l'entité `climate`)
+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 facultative de capteur de donnant la date et heure de dernière vue du capteur (`last_seen`). Si vous avez ce capteur donnez le ici, il permet d'éviter des mises en sécurité lorsque la température est stable et que le capteur ne remonte plus de température pendant longtemps. (cf. [ici](troubleshooting.md#pourquoi-mon-versatile-thermostat-se-met-en-securite-)),
+6. une durée de cycle en minutes. A chaque cycle :
+   1. `over_switch` : VTherm allumera/éteindra le radiateur en modulant la proportion de temps allumé,
+   2. `over_valve` : VTherm calculera une nouvelle ouverture de la vanne et lui enverra si elle a changée,
+   3. `over_climate` : le cycle permet d'effectuer les contrôles de base et recalcule les coefficients de l'auto-régulation. Le cycle peut déboucher sur une nouvelle consigne envoyée au sous-jacents ou sur une modification d'ouverture de la vanne dans le cas d'un _TRV_ dont la vanne est commandable.
+7. une puissance de l'équipement ce qui va activer les capteurs de puissance et énergie consommée par l'appareil. Si plusieurs équipements sont reliés au même VTherm, il faut indiquer ici le total des puissances max des équipements,
+8.  la possibilité d'utiliser des paramètres complémentaires venant de la configuration centralisée :
+    1.  capteur de température extérieure,
+    2.  température minimale / maximale et pas de température
+9.  la possibilité de controler le thermostat de façon centralisée. Cf [controle centralisé](#le-contrôle-centralisé),
+10. une case à cocher si ce VTherm est utilisé pour déclencher une éventuelle chaudière centrale.
+
+> ![Astuce](images/tips.png) _*Notes*_
+>  1. avec les types ```over_switch``` et ```over_valve```, 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** mais doit être adapté à votre type de chauffage. Plus l'inertie est grande et plus le cycle doit être long. Cf. 'TODO exemples de reglages,
+>  2. si le cycle est trop court, le radiateur ne pourra jamais atteindre la température cible. Pour le radiateur à accumulation par exemple il sera sollicité inutilement.
+
+# Choix des fonctions utilisées
+
+Choisissez le menu "Fonctions".
+
+![image](images/config-features.png)
+
+Les différentes fonctions que vous souhaitez utiliser pour ce VTherm :
+1. la détection d'ouvertures (portes, fenêtres) permettant de stopper le chauffage lorsque l'ouverture est ouverte. (cf. [gestion des ouvertures](feature-window.md))
+2. la détection de mouvement : VTherm peut adapter une consigne de température lorsqu'un mouvement est détecté dans la pièce. (cf. [détection du mouvement](feature-motion.md))
+3. la gestion de la puissance : VTherm peut stopper un équipement si la puissance consommée dans votre habitation dépasse un seuil. (cf. [gestion du délestage](feature-power.md))
+4. la détection de présence : si vous avez un capteur indiquant une présence ou non dans votre habitation, vous pouvez l'utiliser pour changer la température de consigne. Cf. [gestion de la présence](feature-presence.md). Attention de ne pas confondre cette fonction avec la détection de mouvement. La présence est plus faite pour être à l'échelle de l'habitation alors que le mouvement est plus fait pour être à l'échelle de la pièce.
+5. l'arrêt/démarrage automatique : pour les VTherm de type `over_climate` uniquement. Cette fonction permet d'arrêter un équipement lorsque VTherm détete qu'il ne sera plus néessaire pendant un certain temps. Il utilise la courbe de température pour prévoir quand l'équipement sera de nouveau utile et le rallumera à ce moment là. Cf. [gestion de l'arrêt/démarrage automatique](feature-auto-start-stop.md)

+>
+> Trois façons de travailler avec les VTherms sont disponibles :
+> 1. Chaque Versatile Thermostat est entièrement configurée de manière indépendante. Choisissez cette option si vous ne souhaitez avoir aucune configuration ou gestion centrale.
+> 2. Certains aspects sont configurés de manière centralisée. Cela permet par ex. définir la température min/max, la détection de fenêtre ouverte,… au niveau d'une instance centrale et unique. Pour chaque VTherm que vous configurez, vous pouvez alors choisir d'utiliser la configuration centrale ou de la remplacer par des paramètres personnalisés.
+> 3. En plus de cette configuration centralisée, tous les VTherm peuvent être contrôlées par une seule entité de type `select`. Cette fonction est nommé `central_mode`. Cela permet de stopper / démarrer / mettre en hors gel / etc tous les VTherms en une seule fois. Pour chaque VTherm, l'utilisateur indique si il est concerné par ce `central_mode`.

+
+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 en sélectionnant dans le menu l'option à configurer.
+
+# Choix d'un type de VTherm
+
+## Configuration centralisée
+Ce choix permet de configurer une fois pour tous les VTherms certains aspects qui peuvent être répétitifs comme :
+1. les paramètres des différents algorithmes (TPI, détection d'ouvertures, détection de mouvements, capteurs de puissance de votre habitation, la détection de présence). Tous ces paramètres sont transverses à tous les VTherms. Vous pouvez donc ne les saisir qu'une seule fois dans la `Configuration centralisée`. Cette configuration ne créé pas de VTherm à proprement parler. Elle permet juste de mettre en commun des paramètres qu'il serait fastidieux de resaisir pour chaque VTherm. Noter que vous pouvez surcharger les paramètres sur les VTherms pour les spécialisés au besoin,
+2. la configuration de la commande d'un chauffage central,
+3. certains paramètre avancés comme la mise en sécurité
+
+## VTherm sur un switch
+Ce VTherm permet de contrôler un interrupteur qui allume ou étient un radiateur. Cet interrupteur peut être un interrupteur physique qui allume ou éteint directement un radiateur (souvent électrique) ou un interrupteur virtuel qui pourra effectuer les actions que vous voulez sur demande d'allumage ou extinction. Ce dernier type permet par exemple de commander des switchs avec fil pilote ou deu DIY avec diode pour fil pilote. VTherm va moduler la proportion de temps allumé vs éteint pour obtenir la température souhaitée. Si il fait froid, il allume plus souvent (jusqu'à 100%), si il fait chaud il baisse le pourcentage d'allumage. Ce pourcentage d'allumage en nommé `on_percent`.
+
+Les entités sous-jacentes sont donc des `switchs` ou des `input_boolean`.
+
+## Vtherm sur un autre thermostat
+Lorsque votre équipement est contrôlé par une entité de type `climate` dans Home Assistant et que vous n'avez que ça à disposition, vous devez utiliser ce type de VTherm. Dans ce cas, le VTherm va simplement commander la température de consigne du `climate` sous-jacent.
+Ce type est aussi équipé de fonction d' auto-régulations avancées permettant de moduler la consigne donnée aux sous-jacent pour atteindre plus vite la consigne et de s'affranchir de la régulation interne de ces équipements qui est parfois mauvaise. C'est le cas, si le thermomètre interne de l'équipement est trop proche du corps de chauffe. L'équipement peut croire qu'il fait chaud alors qu'au bout de la pièce, la consigne n'est pas du tout atteinte.
+
+Depuis la version 6.8, ce type de VTherm permet aussi de réguler avec une action directe sur la vanne. Idéal pour les _TRV_ pour lesquels la vanne est commandable, ce type est recommandé si vous êtes équipés.
+
+Les entités sous-jacentes de ce type de VTherm sont donc des `climate` exclusivement.
+
+## VTherm sur une vanne
+Lorsque tout ce que vous avez à disposition pour réguler la température de votre radiateur est une entité de type `number` vous devez utiliser le type `over_valve`. VTherm ouvre ou ferme la vanne en fonction de l'écart entre la consigne et la température réelle de la pièce (et de la température extérieure).
+
+Ce type peut être utilisé pour les _TRV_ qui n'ont pas de `climate` associé ou tout autre solution type DIY qui expose une entité `number`.
+
+# Le bon choix
+> ![Astuce](images/tips.png) _*Comment choisir le type*_
+> Le choix du type est important. Il n'est plus possible de le modifier via l'IHM de configuration. Pour bien chsoisir, il faut se poser les quelques questions suivantes :
+> 1. **quel type d'équipement je vais piloter ?** Dans l'ordre voici ce qu'il faut faire :
+>    1. si vous avez une vanne thermostatique (_TRV_) commandable dans Home Assistant via une entité de type ```number``` (par exemple une _Shelly TRV_), choisissez le type `over_valve`. C'est le type le plus direct et qui assure la meilleure régulation,
+>    2. si vous avez un radiateur électrique (avec ou sans fil pilote) et qu'une entité de type ```switch``` permet de l'allumer ou de l'éteindre, alors le type ```over_switch``` est préférable. La régulation sera faite par le Versatile Thermostat en fonction de la température mesuré par votre thermomètre, à l'endroit ou vous l'avez placé,
+>    3. dans tous les autres cas, utilisez le mode ```over_climate```. Vous gardez votre entité ```climate``` d'origine et le Versatile Thermostat "ne fait que" piloter le on/off et la température cible de votre thermostat d'origine. La régulation est faite par votre thermostat d'origine dans ce cas. Ce mode est particulièrement adapté aux climatisations réversible tout-en-un dont l'exposition dans Home Assistant se limite à une entité de type ```climate```. Une auto-régulation avancée permet d'atteindre la consigne en forçant la consigne ou un pilotant directement la vanne lorsque c'est possible.
+> 2. **quelle type de régulation je veux ?** Si l'équipement piloté possède son propre mécanisme de régulation (clim, certaine vanne TRV) et que cette régulation fonctionne bien, optez pour un ```over_climate```. Si l'équipement est de type _TRV_ avec une vanne pilotable sous HA, alors le type `over_climate` avec une auto-régulation `Contrôle direct de la vanne` est le meilleur choix.

+    - [La mise en sécurité](#la-mise-en-sécurité)
+
+Ces paramètres permettent d'affiner le fonctionnement du thermostat et notamment la mise en sécurité d'un _VTherm_. L'absence d'un capteur de température (pièce ou extérieur) peut être dangereux pour votre logement. Supposez que le capteur de température soit bloqué sur 10°. Le _VTherm_ de type `over_climate` ou `over_valve` va alors commander un chauffage maximal des équipements sous-jacents, ce qui peut conduire à une surchauffe de la pièce voire des dommages sur le logement avec au pire un début d'incendie.
+
+Pour éviter cela, _VTherm_ s'assure que les thermomètres répondent bien de façon régulière et met le _VTherm_ dans un mode particuliers nommée le mode sécurité si ce n'est plus le cas. Le mode sécurité consiste à assurer un minimum de chauffe pour éviter l'effet inverse : une habitation qui ne serait plus chauffée du tout en plein hiver par exemple.
+
+Là où le problème devient compliqué, c'est que certain thermomètre - notamment à pile - n'envoie leur température que si elle change. Il est donc tout à fait possible de ne plus recevoir de mises à jour de température pendant plusieurs heures sans que le thermomètre soit en défaut. Les différents paramètres ci-dessous vont permettre de régler finement les seuils de passage en mode sécurité.
+
+Si votre thermomètre est muni d'un capteur nommé `last seen` qui donne l'heure de son dernier contact, il est possible de le spécifier dans les attributs principaux du _VTherm_ pour limiter grandement les fausses mises en sécurité. Cf. [configuration](base-attributes.md#choix-des-attributs-de-base) et [dépannage](troubleshooting.md#pourquoi-mon-versatile-thermostat-se-met-en-securite-).
+
+Pour les _VTherm_ `over_climate` et donc qui se régule lui-même, le mode sécurité est désactivé. En effet il n'y a pas de risque de danger si l'équipement se régule lui-même mais juste un risque de mauvaise température.
+
+## Configuration avancée
+
+Le formulaire de configuration avancée est le suivant :
+
+![image](images/config-advanced.png)
+
+### Délai minimal d'activation
+
+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. Ce paramètre ne sert qu'au _VTherm_ avec un déclenchement cyclique `over_switch`. Si le temps d'allumage est trop court, la, commutation rapide ne permettra pas à l'équipement de monter en température.
+
+### La mise en sécurité
+
+Le deuxième délai (`security_delay_min`) est le délai maximal entre deux mesures de température avant de passer le _VTherm_ en mode sécurité.
+
+Le troisième paramètre (`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. En effet, il n'y a pas de risque physique pour le logement dans ce cas mais juste un risque de surchauffe ou de sous-chauffe.
+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). Ce peut ê
+
+Le quatrième paramètre (`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.
+
+Il est possible de désactiver la mise en sécurité suite à une absence de données du thermomètre extérieure. En effet, celui-ci ayant la plupart du temps un impact faible sur la régulation (dépendant de votre paramètrage), il est possible qu'il soit absent sans mettre en danger le logement. Pour cela, il faut ajouter les lignes suivantes dans votre `configuration.yaml` :
+```
+versatile_thermostat:
+...
+    safety_mode:
+        check_outdoor_sensor: false
+```
+Par défaut, le thermomètre extérieur peut déclencher une mise en sécurité si il n'envoit plus de valeur. N'oubliez pas que Home Assisstant doit être redémarré pour que ces modifications soient prises en compte. Ce réglage est commun à tous les _VTherm_ (qui devraient partager le thermomètre extérieur.
+
+> ![Astuce](images/tips.png) _*Notes*_
+> 1. Lorsque le capteur de température viendra à la vie et renverra les températures, le préréglage sera restauré à sa valeur précédente,
+> 2. 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",
+> 3. Une action est disponible qui permet de régler les 3 paramètres de sécurité. Ca peut servir à adapter la fonction de sécurité à votre usage,
+> 4. Pour un usage naturel, le ``security_default_on_percent`` doit être inférieur à ``security_min_on_percent``,
+> 5. Si vous utilisez la carte Verstatile Thermostat UI (cf. [ici](additions.md#bien-mieux-avec-le-versatile-thermostat-ui-card)), un _Vtherm_ en mode sécurité est signalé par un voile grisatre qui donne le thermomètre en défaut et depuis combien de temps le thermomètre n'a pas remonté de valeur : ![mode sécurité](images/safety-mode-icon.png).

+
+Cette fonction 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.
+Exclusiveme réservé au _VTherm_ de type `over_climate`, elle répond au cas d'usage suivant :
+1. votre équipement est allumé électriquement en permanence et consomme de l'électricité même lorsqu'il n'y a pas besoin de chauffer (resp. refroidir). C'est souvent le cas sur les _PAC_ qui consomment même en veille,
+2. les conditions de température font qu'il n'y a pas besoin de chauffer (resP. refroidir) pendant longtemps : la consigne est supérieure (resp. inférieur) à la température de la pièce,
+3. la température monte (resp. descend), est stable ou descend (resp. monte) doucement
+
+Dans ce cas, il est préférable de demander à l'équipement de s'éteindre pour éviter la consommation électrique en mode veille.
+
+## Configurer l'auto-start/stop
+
+
+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'.
+
+![image](images/config-auto-start-stop.png)
+
+Le réglage 'Lent' permet d'avoir environ 30 min entre un arrêt et une relance,
+Le réglage 'Moyen' met le seuil a environ 15 min et le réglage rapide le met à 7 min.
+
+Attention, ce ne sont pas des réglages absolus puisque l'algorithme tient compte de la pente de la courbe température de la pièce pour réagir. Il est toujours possible qu'un démarrage ait lieu peu après une extinction si la chute de température est importante.
+
+## Usage
+
+Une fois la fonction paramétrée, 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`.

+  - [Avertissement](#avertissement)
+
+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.
+
+## Principe
+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 chaudière centrale' :
+
+![Ajout d'une chaudière centrale](images/config-central-boiler-1.png)
+
+Sur la page suivante vous pouvez donner la configuration des actions (ex services) à appeler lors de l'allumage / extinction de la chaudière :
+
+![Ajout d'une chaudière centrale](images/config-central-boiler-2.png)
+
+Les actions (ex 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 la bonne action ?
+Pour trouver l'action à utiliser, le mieux est d'aller dans "Outils de développement / Actions", chercher l'action à appeler, l'entité à commander et l'éventuel paramètre à donner.
+Cliquez sur 'Appeler l'action'. 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 :
+```
+event_type: versatile_thermostat_central_boiler_event
+data:
+  central_boiler: true
+  entity_id: binary_sensor.central_boiler

+  parent_id: null
+  user_id: null
+```
+
+Un évènement d'extinction :
+```

+  parent_id: null
+  user_id: null
+```
+
+## 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.

+# Le contrôle centralisé
+
+- [Le contrôle centralisé](#le-contrôle-centralisé)
+  - [Configuration du contrôle centralisée](#configuration-du-contrôle-centralisée)
+  - [Usage](#usage)
+
+Cette fonction vous permet de contrôler tous vos _VTherm_ depuis un unique point de contrôle.
+Le cas d'usage typique est lorsque vous partez pour une longue durée, vous voulez mettre tous vos _VTherm_ en Hors-gel et lorsque vous rentrez, vous voulez les remettre dans l'état initial.
+
+Le contrôle centralisé se fait depuis un _Vtherm_ spécial nommé configuration centralisée. Cf. [ici](creation.md#configuration-centralisée) pour plus d'informations.
+
+## Configuration du contrôle centralisée
+
+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.
+
+![central_mode](images/central-mode.png)
+
+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 de façon autonome,
+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,
+4. `Cool only` : tous les VTherms sont mis en mode climatisation lorsque ce mode est supporté par le VTherm, sinon il est stoppé,
+5. `Frost protection` : tous les VTherms sont mis en preset hors-gel lorsque ce preset est supporté par le VTherm, sinon il est stoppé.
+
+## Usage
+
+Pour qu'un VTherm soit contrôlable de façon centralisée, il faut que son attribut de configuration nommé `use_central_mode` soit vrai. Cet attribut est disponible dans la page de configuration `Principaux ttributs`
+
+![central_mode](images/use-central-mode.png)
+
+Il est donc possible de contrôler tous les VTherms (que ceux que l'on désigne explicitement) avec un seul contrôle.

+  - [Usage](#usage)
+
+Cette fonction vous permet de changer de preset lorsqu'un mouvement est détectée dans une pièce. Si vous ne souhaitez chauffer votre bureau, lorsque la pièce est occupée et uniquement si la pièce est occupée, il vous faut un capteur de mouvement (ou de présence) dans la pièce et configurer cette fonction.
+
+Cette fonction est souvent confondue avec la fonction de présence. Elles sont complémentaires mais ne se remplace pas. La fonction 'mouvement' est locale à une pièce équipe d'un capteur de mouvement alors que la fonction 'présence' est prévue pour être globale à tout le logement.
+
+## Configurer le mode d'activité ou la détection de mouvement
+
+Si vous avez choisi la fonctionnalité `Avec détection de mouvement`, :
+
+![image](images/config-motion.png)
+
+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 d'activation** (en secondes) définissant combien de temps nous attendons la confirmation du mouvement avant de considérer le mouvement. Ce paramètre peut être **supérieur à la temporisation de votre détecteur de mouvement**, sinon la détection se fera à chaque mouvement signalé par le détecteur,
+- une durée de fin **délai de désactivation** (en secondes) définissant combien de temps nous attendons la confirmation d'une fin de mouvement avant de ne plus 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.
+
+## Usage
+
+Pour indiquer à un _VTherm_ qu'il doit écouter le capteur de mouvement, vous devez le mettre dans le preset spécial 'Activité'. Si vous avez installé la carte Versatile Thermostat UI (cf. [ici](additions.md#bien-mieux-avec-le-versatile-thermostat-ui-card)), ce preset est représenté comme suit : ![preset Activité](images/activity-preset-icon.png).
+
+Vous pouvez ainsi, sur demande, mettre un _VTherm_ en mode détection de mouvement.
+
+Le comportement va être le suivant :
+- nous avons une pièce avec un thermostat réglé en mode activité, le mode "mouvement" choisi est confort (21,5°C), le mode "pas de mouvement" choisi est Eco (18.5°C) et la temporisation du mouvement est de 30 sec lors de la détection et de 5 minutes sur fin de détection.
+- la pièce est vide depuis un moment (aucune activité détectée), la température de consigne de cette pièce est de 18,5°
+- quelqu'un entre dans la pièce, une activité est détectée si le mouvement est présent pendant au moins 30 sec. La température passe alors à 21,5°
+- si le mouvement est présent pendant moins de 30 sec (passage rapide), la température reste sur 18,5°,
+- imaginons que la température soit passée sur 21,5°, lorsque la personne quitte la pièce, au bout de 5 min la température est ramenée à 18,5°.
+- si la personne revient avant les 5 minutes, la température reste sur 21,5°
+
+> ![Astuce](images/tips.png) _*Notes*_
+>    1. Sachez que comme pour les autres preset, `Activité` ne sera proposé que s'il est correctement configuré. En d'autres termes, les 4 clés de configuration doivent être définies

+
+- [Gestion de la puissance - délestage](#gestion-de-la-puissance---délestage)
+  - [Configurer la gestion de la puissance](#configurer-la-gestion-de-la-puissance)
+
+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.
+Vous aurez besoin d'un **capteur de la puissance totale instantanée consommée** de votre logement ainsi que d'un **capteur donnant la puissance maximale autorisée**.
+
+Le comportement de cette fonction est basique :
+1. lorsque le _VTherm_ va allumer un équipement,
+2. il compare la dernière valeur connue du capteur de puissance consommée avec la dernière valeur de la puissance maximale autorisée. Si il reste une marge supérieure égale à la puissance déclarée des équipements du _VTherm_ alors le VTherm et ses équipements seront allumés. Sinon ils resteront éteints jusqu'au prochain cycle.
+
+ATTENTION: ce fonctionnement très basique **n'est pas une fonction de sécurité** mais plus une fonction permettant une optimisation de la consommation au prix d'une dégradation du chauffage. Des dépassements sont possibles selon la fréquence de remontée de vos capteurs de consommation, la puissance réellement utilisée par votre équipements. Vous devez donc toujours garder une marge de sécurité.
+
+Cas d'usage type:
+1. vous avez un compteur électrique limité à 11 kW,
+2. vous chargez de temps en temps un véhicle électrique à 5 kW,
+3. il reste donc 6 kW pour tout le reste y compris le chauffage,
+4. vous avez 1 kW d'autres équipements en cours,
+5. vous avez déclaré un capteur (`input_number`) de puissance max autorisée à 9 kW (= 11 kW  - la réserve pour les autres équipements - marge)
+
+Si la vehicle est en charge, la puissance totale consommé est de 6 kW (5+1) et un _VTherm_ ne s'allumera que si sa puissance déclarée est de 3 kW max (9 kW - 6 kW).
+Si la vehicle est en charge et qu'un autre _VTherm_ de 2 kW est allumé, la puissance totale consommé est de 8 kW (5+1+2) et un _VTherm_ ne s'allumera que si sa puissance déclarée est de 1 kW max (9 kW - 8 kW). Sinon il passe son tour (cycle).
+
+Si le vehicle n'est pas en charge, la puissance totale consommé est de 1 kW, un _VTherm_ ne s'allumera que si sa puissance déclarée est de 8 kW max (9 kW - 1 kW).
+
+## Configurer la gestion de la puissance
+
+Si vous avez choisi la fonctionnalité `Avec détection de la puissance`, vous la configurez de la façon suivante :
+![image](images/config-power.png)
+
+1. l'id d'entité du **capteur de puissance instantané consommé** de votre logement,
+2. l'id d'entité du **capteur de puissance maximale autorisée**,
+3. la température à appliquer si le délestage est appliqué.
+
+Notez que toutes les valeurs de puissance doivent avoir les mêmes unités (kW ou W par exemple).
+Le fait d'avoir un **capteur de puissance maximale autorisée**, vous permet de modifier la puissance maximale au fil du temps à l'aide d'un planificateur ou d'une automatisation.
+
+> ![Astuce](images/tips.png) _*Notes*_

+
+Vous devez avoir choisi la fonctionnalité ```Avec détection des ouvertures``` dans la première page pour arriver sur cette page.
+La détection 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)
+
+La configuration de la détection d'ouverture est la suivante :
+
+![image](images/config-window-main.png)
+
+## Le mode capteur
+Pour passer en mode capteur, vous devez donner une entité de type `binary_sensor` ou `input_boolean`.
+Dans ce mode, vous devez renseigner les informations suivantes:
+
+![mode window capteur](images/config-window-sensor.png)
+
+1. un **délai en secondes** avant tout changement. Cela permet d'ouvrir rapidement une fenêtre sans arrêter le chauffage,
+2. l'action a réaliser lorsque l'ouverture est détectée ouverte. Les actions possibles sont :
+   1. _Eteindre_ : le VTherm sera étient,
+   2. _Ventilateur seul_ : le chauffage ou refroidissement sera coupé mais l'équipement continuera à ventiler (pour les équipements compatibles),
+   3. _Hors gel_ : la température du preset 'Hors Gel' sera alors sélectionné sur le _VTherm_ sans changement du preset courant (cf. notes ci-dessous),
+   4. _Eco_ : la température du preset _Eco_ sera appliquée sur le _VTherm_ sans changement du preset courant (cf. notes ci-dessous).
+
+Lorsque le détecteur passe à ouvert :
+1. _VTherm_ attend le délai indiqué,
+2. si l'ouverture est toujours ouverte au bout du délai, l'état du _VTherm_ est mémorisée (mode Chauffe / Froid / ..., preset courant, temperature de consigne courante) et l'action est réalisée
+
+Pareil, lorsque le détecteur passe à fermé :
+1. _VTherm_ attend le délai indiqué,
+2. si l'ouverture est toujours fermée au bout du délai, l'état avant ouverture mémorisé est restauré.
+
+## Le mode auto
+En mode auto, la configuration est la suivante:
+![image](images/config-window-auto.png)
+
+1. un **délai en secondes** avant tout changement. Cela permet d'ouvrir rapidement une fenêtre sans arrêter le chauffage,
+2. un seuil de détection en degré par heure. 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),
+3. un seuil de fin de détection en degré par heure. Lorsque la chute de température repassera au-dessus cette valeur, le thermostat se remettra dans le mode précédent (mode et preset),
+4. 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
+5. l'action a réaliser lorsque l'ouverture est détectée ouverte. Les actions sont les mêmes qu'en mode capteur décrit ci-dessus.
+
+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 : 3 °C/heure
+- seuil de non détection: 0 °C/heure
+- durée max : 30 min.
+
+Un nouveau capteur nommé "slope" a été ajouté pour tous les thermostats. Il donne la pente de la courbe de température en °C/heure (ou °K/heure). Cette pente est lissée et filtrée pour éviter les valeurs abérrantes des thermomètres qui viendraient pertuber la mesure.
+
+![image](images/temperature-slope.png)
+
+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](images/window-auto-tuning.png)
+
+> ![Astuce](images/tips.png) _*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, ...)
+>  5. Pour éviter d'interférer avec votre réglage de preset courant, Les actions _Hors gel_ et _Eco_ change la température cible sans changer le preset. Donc, vous pouvez constater un écart entre le preset sélectionné et la consigne.
