I hope this is the right place for this.
I have the following feature requests:
1.) Support the min temp of 6°C
2.) Support the off feature so that the heating can be switched off via the Google Assistant/Home integration of HA. It would be fine to do so by letting this set the temp to 6°C on the device
3.) Support the battery status that can be read from the json of the device
4.) Support zones by setting device IDs
