 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

+#### 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.

+
+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.

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 totale des équipements du VTherm** (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.

 > 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

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).

 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.

+Depuis la version 5.3 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` :

 ## 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 :

+
+## 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 :
+```
+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.

 ### 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).

Cette fonction permet de compenser le biais de mesure des thermomètres internes. Si le biais est important la régulation doit être importante.

-# Major changes in version 5.0
-![New](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/new-icon.png?raw=true)
+# Changes in version 6.0
+
+## Temperature entities for presets
+Preset temperatures are now directly accessible in the form of entities linked to VTherm.
+Example :
+
+![Temperature entities](images/temp-entities-1.png)
+
+The Boost, Comfort, Eco and Frost Protection entities allow you to directly adjust the temperatures of these presets without having to reconfigure the VTHerm in the configuration screens.
+These modifications persist after a restart and are taken into account immediately by VTherm.
+
+Depending on the functions activated, the list of temperatures may be more or less complete:
+1. If presence management is activated, absence presets are created. They are suffixed with 'abs' for absence,
+2. If air conditioning management (AC Mode) is activated, air conditioning mode presets are created. They are suffixed with 'clim' for air conditioning. Only the Frost protection preset has no equivalent in air conditioning mode,
+3. The different absent and air conditioning combinations can be created depending on the configuration of the VTherm
+
+If a VTherm uses the presets of the central configuration, these entities are not created, because the temperatures of the presets are managed by the central configuration.
+
+### In the case of a central configuration
+If you have configured a central configuration, this also has its own presets which meet the same rules as stated above.
+Example of a central configuration with presence management and AC (air conditioning) mode:
+
+![Temperature entities](images/temp-entities-2.png)
+
+In the case of a change of a central configuration temperature, all VTherms that use this preset are immediately updated.
+
+## Redesign of the configuration menu
+The configuration menu has been completely revised. It dynamically adapts to the user's choices and allows direct access to the settings of the desired function without having to go through the entire configuration tunnel.
+
+To create a new VTherm, you will first need to choose the type of VTherm:
+
+![VTherm choice](images/config-main0.png)
+
+Then, you now access the following configuration menu:
+
+![VTherm menu](images/config-menu.png)
+
+Each part to be configured is directly accessible, without having to go through the entire configuration tunnel as before.
+
+You will note the menu option named `Functions` which allows you to choose which functions will be implemented for this VTherm:
+
+![VTherm features](images/config-features.png)
+
+Depending on your choices, the main menu will adapt to add the necessary options.
+
+Example of menu with all functions checked:
+
+![VTherm menu](images/config-menu-all-options.png)
+You can see that the 'Opening detection', 'Motion detection', 'Power management' and 'Presence management' options have been added. You can then configure them.
+
+### The 'Incomplete configuration' and 'Finalize' menu options
+
+The last menu option is special. It allows you to validate the creation of the VTherm when all the functions have been correctly configured.
+If one option is not configured correctly, the last option is:
+
+![Incomplete configuration](images/config-not-complete.png)
+
+Its selection does nothing but prevents you from finalizing the creation (resp. modification) of the VTherm.
+**You must then search in the options which one is missing**.

+Once all configuration is valid, the last option changes to:

+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).
+
+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.
+
+This adjustment is specific to each device, making the heating system more accurate and avoiding issues from faulty sensor readings.
+See ![Use of internal temperature](images/config-use-internal-temp.png)
+
+#### synthesis of the self-regulation algorithm
+The self-regulation algorithm can be summarized as follows:
+
+1. initialize the target temperature as the VTherm setpoint,
+1. If self-regulation is activated,
+    1. calculates the regulated temperature (valid for a VTherm),
+    2. take this temperature as a target,
+2. For each underlying of the VTherm,
+      1. If "use internal temperature" is checked,
+           1. calculates the offset (trv internal temp - room temp),
+      2. Adding the offset to the target temperature,
+      3. sends the target temperature (= regulated temp + (internal temp - room temp)) to the underlying
+
 #### Auto-fan mode
 This mode introduced in 4.3 makes it possible to force the use of ventilation if the temperature difference is significant. In fact, by activating ventilation, distribution occurs more quickly, which saves time in reaching the target temperature.
 You can choose which ventilation you want to activate between the following settings: Low, Medium, High, Turbo.

 If your equipment does not include Turbo mode, Forte` mode will be used as a replacement.
 Once the temperature difference becomes low again, the ventilation will go into a "normal" mode which depends on your equipment, namely (in order): `Silence (mute)`, `Auto (auto)`, `Low (low)`. The first value that is possible for your equipment will be chosen.

+#### 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.

+
+## Control of a central boiler
+
+Since release 5.3, you have the possibility of controlling a centralized boiler. From the moment it is possible to start or stop this boiler from Home Assistant, then Versatile Thermostat will be able to control it directly.
+
+The principle put in place is generally as follows:
+1. a new entity of type `binary_sensor` and named by default `binary_sensor.central_boiler` is added,
+2. in the VTherms configuration you indicate whether the VTherm should control the boiler. Indeed, in a heterogeneous installation, some VTherm must control the boiler and others not. You must therefore indicate in each VTherm configuration whether it controls the boiler or not,
+3. the `binary_sensor.central_boiler` listens for changes in state of VTherm equipment marked as controlling the boiler,
+4. as soon as the number of devices controlled by the VTherm requesting heating (ie its `hvac_action` goes to `Heating`) exceeds a configurable threshold, then the `binary_sensor.central_boiler` goes to `on` and **if a activation service has been configured, then this service is called**,
+5. if the number of devices requiring heating falls below the threshold again, then the `binary_sensor.central_boiler` goes to `off` and if **a deactivation service has been configured, then this service is called**,
+6. you have access to two entities:
+    - one of type `number` named by default `number.boiler_activation_threshold`, gives the trigger threshold. This threshold is in number of equipment (radiators) which requires heating.
+    - one of type `sensor` named by default `sensor.nb_device_active_for_boiler`, gives the number of devices requiring heating. For example, a VTherm having 4 valves including 3 heating requests will increase this sensor to 3. Only VTherm equipment that is marked to control the central boiler is counted.
+
+You therefore always have the information which allows you to control and adjust the activation of the boiler.
+
+All these entities are attached to the central configuration service:
+![The entities controlling the boiler](images/entitites-central-boiler.png)
+
+### Setup
+To configure this function, you must have a centralized configuration (see [Configuration](#configuration)) and check the 'Add a central boiler' box:
+
+![Adding a central boiler](images/config-central-boiler-1.png)
+
+On the following page you can configure the services to be called when switching the boiler on/off:
+
+![Adding a central boiler](images/config-central-boiler-2.png)
+
+The services are configured as indicated on the page:
+1. the general format is `entity_id/service_id[/attribute:value]` (where `/attribute:value` is optional),
+2. `entity_id` is the name of the entity that controls the boiler in the form `domain.entity_name`. For example: `switch.boiler` for boilers controlled by a switch or `climate.boiler` for a boiler controlled by a thermostat or any other entity which allows control of the boiler (there is no limitation). We can also switch inputs (`helpers`) like `input_boolean` or `input_number`.
+3. `service_id` is the name of the service to call in the form `domain.service_name`. For example: `switch.turn_on`, `switch.turn_off`, `climate.set_temperature`, `climate.set_hvac_mode` are valid examples.
+4. For some service you will need a parameter. This can be the 'HVAC Mode' `climate.set_hvac_mode` or the target temperature for `climate.set_temperature`. This parameter must be configured in the form `attribute:value` at the end of the string.
+
+Examples (to be adjusted to your case):
+- `climate.chaudiere/climate.set_hvac_mode/hvac_mode:heat`: to turn on the boiler thermostat in heating mode,
+- `climate.chaudiere/climate.set_hvac_mode/hvac_mode:off`: to stop the boiler thermostat,
+- `switch.pompe_chaudiere/switch.turn_on`: to turn on the switch which powers the boiler pump,
+- `switch.pompe_chaudiere/switch.turn_off`: to turn on the switch which powers the boiler pump,
+- ...
+
+### How to find the right service?
+To find the service to use, the best is to go to "Development tools / Services", look for the service called, the entity to order and the possible parameter to give.
+Click on 'Call Service'. If your boiler lights up you have the correct configuration. Then switch to Yaml mode and copy the parameters.
+
+Example:
+
+Under "Development Tools / Service":
+
+![Service configuration](images/dev-tools-turnon-boiler-1.png)
+
+In yaml mode:
+
+![Service configuration](images/dev-tools-turnon-boiler-2.png)
+
+The service to configure is then the following: `climate.empty_thermostast/climate.set_hvac_mode/hvac_mode:heat` (note the removal of the blank in `hvac_mode:heat`)
+
+Then do the same for the extinguishing service and you are all set.
+
+### The events
+
+Each time the boiler is successfully switched on or off, an event is sent by Versatile Thermostat. It can advantageously be captured by automation, for example to notify a change.
+The events look like this:
+
+An ignition event:
+```
+event_type: versatile_thermostat_central_boiler_event

+
+### Warning
+
+> ![Tip](images/tips.png) _*Notes*_
+> Controlling a central boiler using software or hardware such as home automation can pose risks to its proper functioning. Before using these functions, make sure that your boiler has safety functions and that they are working. Turning on a boiler if all the taps are closed can generate excess pressure, for example.

 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.

 ### Type `over_climate`
 With an `over_climate` type VTherm, the regulation is done by the underlying `climate` directly and VTherm simply transmits the instructions to it. So if the radiator heats up when the set temperature is exceeded, it is certainly because its internal temperature measurement is biased. This happens very often with TRVs and reversible air conditioning units which have an internal temperature sensor, or too close to the heating element (therefore too cold in winter).

 To get around this, VTherm is equipped with a function called self-regulation which allows the instruction sent to the underlying to be adapted until the target temperature is respected. This function compensates for the measurement bias of internal thermometers. If the bias is important the regulation must be important. See [Self-regulation](#self-regulation) to configure self-regulation.

 ## 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`.

 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).
@@ -1225,11 +1606,11 @@ All these parameters are adjusted on the last page of the VTherm configuration:

 2. If the `security_delay_min` parameter is too small, it risks generating a lot of false alerts. A correct value is around 60 min, especially if you have battery-powered temperature sensors.
 3. Some temperature sensors do not send a measurement if the temperature has not changed. So in the event of a very stable temperature for a long time, the safety mode may be triggered. This is not very serious since it is removed as soon as the VTherm receives a temperature again. On certain thermometers (TuYA for example), you can force the maximum delay between 2 measurements. It will be appropriate to set a max delay < `security_delay_min`,
 4. As soon as the temperature is received again the safety mode will be removed and the previous values of preset, target temperature and mode will be restored.
