+# 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.

 # Quand l'utiliser et ne pas l'utiliser
-Ce thermostat peut piloter 2 types d'équipement:
+Ce thermostat peut piloter 3 types d'équipements :
 1. un radiateur qui ne fonctionne qu'en mode marche/arrêt (nommé ```thermostat_over_switch```). La configuration minimale nécessaire pour utiliser ce type thermostat est :
-   a. un équipement comme un radiateur (un ```switch``` ou équivalent),
-   b. une sonde de température pour la pièce (ou un input_number),
-   c. un capteur de température externe (pensez à l'intégration météo si vous n'en avez pas)
+   1. un équipement comme un radiateur (un ```switch``` ou équivalent),
+   2. une sonde de température pour la pièce (ou un input_number),
+   3. un capteur de température externe (pensez à l'intégration météo si vous n'en avez pas)
 2. un autre thermostat qui a ses propres modes de fonctionnement (nommé ```thermostat_over_climate```). Pour ce type de thermostat la configuration minimale nécessite :
-   a. un équipement - comme une climatisation une valve thermostatique - qui est pilotée par sa propre entity de type ```climate```,
+   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.
 
-Le type ```thermostat_over_climate``` permet d'ajouter à votre équipement existant toutes les fonctionnalités fournies par VersatileThermostat. L'entité climate VersatileThermostat pilotera votre entité climate, en la coupant si les fenêtres sont ouvertes, la passant en mode Eco si personne n'est présent, etc. Cf. [ici](#pourquoi-une-nouvelle-implémentation-du-thermostat). Pour ce type de thermostat, les cycles éventuels de chauffe sont pilotés par l'entité climate sous-jacente et pas par le Versatile Thermostat lui-même.
+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.
 
-Parce que cette intégration vise à commander le radiateur en tenant compte du préréglage configuré (preset) et de la température ambiante, ces informations sont obligatoires.
+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 :
-1. les vannes POPP de Danfoss avec retour de température. Il est impossible d'éteindre cette vanne et elle d'auto-régule d'elle-même causant des conflits avec le VTherm,
-2. les vannes thermstatiques "Homematic radio". Elles ont un cycle de service incompatible avec une commande par le Versatile Thermostat

+> 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```
+> 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 plusieurs entités de type sont configurées, la thermostat décale les activations afin de minimiser le nombre de switch actif à un instant t. Ca permet une meilleure répartition de la puissance puisque chaque radiateur va s'allumer à son tour.

+#### 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, appelé erreur brute,
+2. l'accumulation des erreurs 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,
+> 5. Si ce n'est toujours pas bon, il faudra passer en mode expert pour pouvoir régler les paramètres de régulation de façon fine. Voir en-dessous
+
+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.
+
+#### L'auto-régulation en mode Expert
+
+En mode **Expert** pouvez régler finement les paramètres de l'auto-régulation pour atteindre vos objeetifs et optimiser au mieux. L'algorithme calcule l'écart entre la consigne et la température réelle de la pièce. Cet écard est appelé erreur.
+Les paramètres réglables sont les suivants :
+1. `kp` : le facteur appliqué à l'erreur brute,
+2. `ki` : le facteur appliqué à l'accumulation des erreurs,
+3. `k_ext` : le facteur appliqué à la différence entre la température intérieure et la température externe,
+4. `offset_max` : le maximum de correction (offset) que la régulation peut appliquer,
+5. `stabilization_threshold` : un seuil de stabilisation qui lorsqu'il est atteint par l'erreur remet à 0, l'accumulation des erreurs,
+6. `accumulated_error_threshold` : le maximum pour l'accumulation d'erreur.
+
+Pour le tuning il faut tenir compte de ces observations :
+1. `kp * erreur` va donner l'offset lié à l'erreur brute. Cet offset est directement proportionnel à l'erreur et sera à 0 lorsque la target sera atteinte,
+2. l'accumulation de l'erreur permet de corriger le stabilisation de la courbe alors qu'il reste une erreur. L'erreur s'accumule et l'offset augmente donc progressivement ce qui devrait finir par stabiliser sur la température cible. Pour que ce paramètre fondamental est un effet il faut qu'il soit pas trop petit. Une valeur moyenne est 30
+3. `ki * accumulated_error_threshold` va donner l'offset maximal lié à l'accumulation de l'erreur,
+4. `k_ext` permet d'appliquer tout de suite (sans attendre une accumulation des erreurs) une correction lorsque la température extérieure est très différente de la température cible. Si la stabilisation se fait trop haut lorsqu'il les écarts de température sont importants, c'est que ce paramètre est trop fort. Il devrait pouvoir être annulé totalement pour laisser faire les 2 premiers offset
+
+Les valeurs préprogrammées sont les suivantes :
+
+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
+
+Pour utiliser le mode Expert il vous faut déclarer les valeurs que vous souhaitez utiliser pour chacun de ces paramètres dans votre `configuration.yaml` sous la forme suivante :
+```
+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
+```
+et bien sur, configurer le mode auto-régulation du VTherm en mode Expert. Tous les VTherm en mode **Expert** utiliseront ces mêmes paramètres.
+
+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).

 > ![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 ;-).

 # When to use / not use
-This thermostat can control 2 types of equipment:
-1. a heater that only works in on/off mode (named ```thermostat_over_switch```). Versatile Thermostat will regulate the length of a heating cycle and the pauses in-between by controlling a binary on/off switch. This mode is e.g. suitable for an electrical radiator controlled by a switch. The minimum configuration required to use this type of thermostat is:
-   - an equipment such as a radiator (a ```switch``` or equivalent),
-   - a temperature probe for the room (or an input_number),
-   - an external temperature sensor (think about weather integration if you don't have one)
-2. another thermostat that has its own operating modes (named ```thermostat_over_climate```). Versatile Thermostat will regulate the target temperature of a climate entity. Common examples for this mode are the control of thermostatic radiator valves (TRV), air-conditions (AC), floor heating systems and pellet heating. For this type of thermostat, the minimum configuration requires:
-   - an equipment such as air conditioning or thermostatic valve (TRV) which is controlled by its own ```climate``` type entity,
+This thermostat can control 3 types of equipment:
+1. a radiator that only operates in on/off mode (called ``thermostat_over_switch```). The minimum configuration necessary to use this type thermostat is:
+   1. equipment such as a radiator (a ``switch``` or equivalent),
+   2. a temperature probe for the room (or an input_number),
+   3. an external temperature sensor (consider weather integration if you don't have one)
+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. The climate VersatileThermostat entity will control your existing climate entity, turning it off if the windows are open, switching it to Eco mode if no one is present, etc. See [here](#why-a-new-implementation-of-the-thermostat). For this type of thermostat, any heating cycles are controlled by the underlying climate entity and not by the Versatile Thermostat itself.

An optional self-regulation function allows the Versatile Thermostat to adjust the temperature given as a setpoint to the underlying in order to reach the setpoint.
 
-Because this integration aims to control the radiator taking into account the configured preset and the ambient temperature, this information is mandatory.
+Installations with pilot wire and activation diode benefit from an option which allows the on/off control of the underlying radiator to be reversed. To do this, use the `over switch` type and check the command inversion option.
+
+## Incompatibilities
 
 Some TRV type thermostats are known to be incompatible with the Versatile Thermostat. This is the case for the following valves:
 1. Danfoss POPP valves with temperature feedback. It is impossible to turn off this valve and it self-regulates, causing conflicts with the VTherm,
-2. “Homematic radio” thermostatic valves. They have a duty cycle incompatible with control by the Versatile Thermostat
+2. “Homematic radio” thermostatic valves. They have a duty cycle incompatible with control by the Versatile Thermostat,

+> ![Tip](https://github.com/jmcollin78/versatile_thermostat/blob/main/images/tips.png?raw=true) _*How to choose the type*_
+> The choice of type is important. Even if it is always possible to modify it afterwards via the configuration HMI, it is preferable to ask yourself the following few questions:
+> 1. **what type of equipment am I going to pilot?** In order, here is what to do:
+>    1. if you have a thermostatic valve (TRV) that can be controlled in Home Assistant via a ```number``` type entity (for example a _Shelly TRV_), choose the `over_valve` type. It is the most direct type and which ensures the best regulation,
+>    2. if you have an electric radiator (with or without pilot wire) and a ```switch``` type entity allows you to turn it on or off, then the ```over_switch``` type is preferable. Regulation will be done by the Versatile Thermostat according to the temperature measured by your thermometer, where you have placed it,
+>    3. in all other cases, use the ```over_climate``` mode. You keep your original `climate` entity and the Versatile Thermostat "only" controls the on/off and the target temperature of your original thermostat. Regulation is done by your original thermostat in this case. This mode is particularly suitable for all-in-one reversible air conditioning systems whose exposure in Home Assistant is limited to a `climate` type entity.
+> 2. **what type of regulation do I want?** If the controlled equipment has its own regulation mechanism (air conditioning, certain TRV valve) and this regulation works well, opt for an ``over_climate```
+It is possible to choose an over switch thermostat which controls air conditioning by checking the "AC Mode" box. In this case, only the cooling mode will be visible.

-The algorithm to be used today is limited to TPI is available. See [algorithm](#algorithm)
-If several type entities are configured, the thermostat staggers the activations in order to minimize the number of active switches at a time t. This allows a better distribution of power since each radiator will turn on in turn.
+The algorithm to use is currently limited to TPI is available. See [algorithm](#algorithm).
+If several type entities are configured, the thermostat shifts the activations in order to minimize the number of switches active at a time t. This allows for better power distribution since each radiator will turn on in turn.

+#### 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,
+> 5. If it is still not good, you will have to switch to expert mode to be able to finely adjust the regulation parameters. See below.
+
+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
+
+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"""
+

+    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).
