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

 #### 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.

 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.
+
+The detection algorithm is described [here](https://github.com/jmcollin78/versatile_thermostat/issues/585).
