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

+# Changements majeurs dans la version 4.0.0
+La puissance de l'appareil doit maintenant être la puissance totale de tous les appareils controlée par le VTherm. Cela permet d'avoir des équipements hétérogènes de puissance différente. Dans le cas de plusieurs appareils contrôlés par un seul VTherm, vous devrez éditer et changer la valeur `device_power`. Vous devez configurer la puissance totale de tous les appareils.

   2. une sonde de température pour la pièce (ou un input_number),
@@ -89,7 +98,9 @@ Ce thermostat peut piloter 3 types d'équipement:
   1. un équipement - comme une climatisation, une valve thermostatique - qui est pilotée par sa propre entity de type ```climate```,
 3. un équipement qui peut prendre une valeur de 0 à 100% (nommée ```thermostat_over_valve```). A 0 le chauffage est coupé, 100% il est ouvert à fond. Ce type permet de piloter une valve thermostatique (cf. valve Shelly) qui expose une entité de type `number.` permetttant de piloter directement l'ouverture de la vanne. Versatile Thermostat régule la température de la pièce en jouant sur le pourcentage d'ouverture, à l'aide des capteurs de température intérieur et extérieur en utilisant l'algorithme TPI décrit ci-dessous.

-The ```thermostat_over_climate``` type allows you to add to your existing equipment all the functionalities provided by VersatileThermostat. The VersatileThermostat climate entity will control your climate entity, turning it off if the windows are open, switching it to Eco mode if no one is present, etc. See [here](#why-a-new-thermostat-implementation). For this type of thermostat, any heating cycles are controlled by the underlying climate entity and not by the Versatile Thermostat itself.
+Le type `over_climate` vous permet d'ajouter à votre équipement existant toutes les fonctionnalités apportées par VersatileThermostat. L'entité climate VersatileThermostat contrôlera votre entité climate sous-jacente, l'éteindra si les fenêtres sont ouvertes, la fera passer en mode Eco si personne n'est présent, etc. Voir [ici] (#pourquoi-un-nouveau-thermostat-implémentation). Pour ce type de thermostat, tous les cycles de chauffage sont contrôlés par l'entité climate sous-jacente et non par le thermostat polyvalent lui-même. Une fonction facultative d'auto-régulation permet au Versatile Thermostat d'ajuster la température donnée en consigne au sous-jacent afin d'atteindre la consigne.
+
+Les installations avec fil pilote et diode d'activation bénéficie d'une option qui permet d'inverser la commande on/off du radiateur sous-jacent. Pour cela, utilisez le type `over switch` et cochez l'option d'inversion de la commande.

 ## Incompatibilités
 Certains thermostat de type TRV sont réputés incompatibles avec le Versatile Thermostat. C'est le cas des vannes suivantes :
@@ -181,12 +192,40 @@ Exemple de déclenchement synchronisé :

 Il est possible de choisir un thermostat over switch qui commande une climatisation en cochant la case "AC Mode". Dans ce cas, seul le mode refroidissement sera visible.

+Si votre équipement est commandé par un fil pilote avec un diode, vous aurez certainement besoin de cocher la case "Inverser la case". Elle permet de mettre le switch à On lorsqu'on doit étiendre l'équipement et à Off lorsqu'on doit l'allumer.

 ### Pour un thermostat de type ```thermostat_over_climate```:
 ![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-linked-entity2.png?raw=true)

 Il est possible de choisir un thermostat over climate qui commande une climatisation réversible en cochant la case "AC Mode". Dans ce cas, selon l'équipement commandé vous aurez accès au chauffage et/ou au réfroidissement.

+#### L'auto-régulation
+Depuis la release 3.8, vous avez la possibilité d'activer la fonction d'auto-régulation. Cette fonction autorise VersatileThermostat à adapter la consigne de température donnée au climate sous-jacent afin que la température de la pièce atteigne réellement la consigne.
+Pour faire ça, le VersatileThermostat calcule un décalage basé sur les informations suivantes :
+1. la différence actuelle entre la température réelle et la température de consigne,
+2. l'accumulation des différences passées,
+3. la différence entre la température extérieure et la consigne
+
+Ces trois informations sont combinées pour calculer le décalage qui sera ajouté à la consigne courante et envoyé au climate sous-jacent.
+
+La fonction d'auto-régulation se paramètre avec :
+1. une dégré de régulation :
+   1. Légère - pour des faibles besoin en auto-régulation. Dans ce mode, le décalage maximal sera de 1,5°,
+   2. Medium - pour une auto-régulation moyenne. Un décalage maximal de 2° est possible dans ce mode,
+   3. Forte - pour un fort besoin d'auto-régulation. Le décalage maximal est de 3° dans ce mode et l'auto-régulation réagira fortement aux changements de température.
+2. Un seuil d'auto-régulation : valeur en dessous de laquelle une nouvelle régulation ne sera pas appliquée. Imaginons qu'à un instant t, le décalage soit de 2°. Si au prochain calcul, le décalage est de 2.4°, il sera pas appliqué. Il ne sera appliqué que la différence entre 2 décalages sera au moins égal à ce seuil,
+3. Période minimal entre 2 auto-régulation : ce nombre, exprimé en minute, indique la durée entre 2 changements de régulation.
+
+Ces trois paramètres permettent de moduler la régulation et éviter de multiplier les envois de régulation. Certains équipements comme les TRV, les chaudières n'aiment pas qu'on change la consigne de température trop souvent.
+
+> ![Astuce](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Conseil de mise en place*_
+> 1. Ne démarrez pas tout de suite l'auto-régulation. Regardez comment se passe la régulation naturelle de votre équipement. Si vous constatez que la température de consigne n'est pas atteinte ou qu'elle met trop de temps à être atteinte, démarrez la régulation,
+> 2. D'abord commencez par une légère auto-régulation et gardez les deux paramètres avec leur valeurs par défaut. Attendez quelques jours et vérifiez si la situation s'est améliorée,
+> 3. Si ce n'est pas suffisant, passez en auto-régulation Medium, attendez une stabilisation,
+> 4. Si ce n'est toujours pas suffisant, passez en auto-régulation Forte.
+
+L'auto-régulation consiste à forcer l'équipement a aller plus loin en lui forçant sa température de consigne régulièrement. Sa consommation peut donc être augmentée, ainsi que son usure.

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

@@ -86,7 +94,10 @@ This thermostat can control 3 types of equipment:
 2. another thermostat which has its own operating modes (named ``thermostat_over_climate```). For this type of thermostat the minimum configuration requires:
   1. equipment - such as air conditioning, a thermostatic valve - which is controlled by its own ``climate'' type entity,
 3. equipment which can take a value from 0 to 100% (called `thermostat_over_valve`). At 0 the heating is cut off, 100% it is fully opened. This type allows you to control a thermostatic valve (see Shelly valve) which exposes an entity of type `number.` allowing you to directly control the opening of the valve. Versatile Thermostat regulates the room temperature by adjusting the opening percentage, using the interior and exterior temperature sensors using the TPI algorithm described below.
-The ```thermostat_over_climate``` type allows you to add all the functionality provided by VersatileThermostat to your existing equipment.

 ### For a thermostat of type ```thermostat_over_climate```:
 ![image](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/config-linked-entity2.png?raw=true)

 It is possible to choose an over climate thermostat which controls reversible air conditioning by checking the “AC Mode” box. In this case, depending on the equipment ordered, you will have access to heating and/or cooling.

+#### Self-regulation
+Since release 3.8, you have the possibility to activate the self-regulation function. This function allows VersatileThermostat to adapt the temperature setpoint given to the underlying climate so that the room temperature actually reaches the setpoint.
+To do this, the VersatileThermostat calculates an offset based on the following information:
+1. the current difference between the actual temperature and the set temperature,
+2. the accumulation of past differences,
+3. the difference between the outside temperature and the setpoint
+
+These three pieces of information are combined to calculate the offset which will be added to the current setpoint and sent to the underlying climate.
+
+The self-regulation function is configured with:
+1. a degree of regulation:
+    1. Light - for low self-regulation needs. In this mode, the maximum offset will be 1.5°,
+    2. Medium - for average self-regulation. A maximum offset of 2° is possible in this mode,
+    3. Strong - for a strong need for self-regulation. The maximum offset is 3° in this mode and the auto-regulation will react strongly to temperature changes.
+2. A self-regulation threshold: value below which new regulation will not be applied. Let us imagine that at a time t, the offset is 2°. If in the next calculation, the offset is 2.4°, it will not be applied. It will only be applied that the difference between 2 offsets will be at least equal to this threshold,
+3. Minimum period between 2 self-regulation changes: this number, expressed in minutes, indicates the duration between 2 regulation changes.
+
+These three parameters make it possible to modulate the regulation and avoid multiplying the regulation sendings. Some equipment such as TRVs and boilers do not like the temperature setpoint to be changed too often.
+
+> ![Tip](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*Implementation tip*_
+> 1. Do not start self-regulation straight away. Watch how the natural regulation of your equipment works. If you notice that the set temperature is not reached or that it is taking too long to be reached, start the regulation,
+> 2. First start with a slight self-regulation and keep both parameters at their default values. Wait a few days and check if the situation has improved,
+> 3. If this is not sufficient, switch to Medium self-regulation, wait for stabilization,
+> 4. If this is still not sufficient, switch to Strong self-regulation.
+
+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.

 If you choose the ```Presence management``` feature, this feature allows you to dynamically changes the temperature of all configured Versatile thermostat's presets when nobody is at home or when someone comes back home. For this, you have to configure the temperature that will be used for each preset when presence is off. When the occupancy sensor turns to off, those tempoeratures will be used.
