 The "hvactargettemperature" is used by the hvacstatus ON command for pre-conditioning the car. 
 This seams to only allow values 19, 20 and 21 or else the pre-conditioning command will not work.
 
+The Kamereon API Key changes periodically, which causes a communication error.
+To fix this error update the API Key in the bindings configuration.
+The new key value can hopefully be found in the renault-api project: [KAMEREON_APIKEY value](https://github.com/hacf-fr/renault-api/blob/main/src/renault_api/const.py) or in the openHAB forums.

-If you do not have a smart charger and want to limit the charge of the battery you can set up an  active 15 minute charge schedule in the MyRenault App.
-Then create a Dimmer item "RenaultCar_ChargeLimit" and set it to 80% for example. This rule will change the RenaultCar_ChargingMode to schedule_mode when the limit is reached.
-This stops charging after the battery level reaches the charge limit.
+If you want to limit the charge of the car battery to less than 100%, this can be done as follows. 
+ 
+ * Set up an active dummy charge schedule in the MyRenault App.
+
+ * Create a Dimmer item "RenaultCar_ChargeLimit" and set it to 80% for example. 
+
+ * Add the ChargeRenaultCarLimit rule using the code below.
+
+The rule will change the RenaultCar_ChargingMode to schedule_mode when the limit is reached.
