Support for Avatto WT200 electric floor heating thermostat

[andreas-bulling]

It would be fantastic if there was support for the Avatto WT200 electric floor heating thermostat - this device is the only one I could find that fits into the the standard 55mm frames.

I have Avatto WT100 thermostat (ordered without wifi, then soldered esp12f). There is no support for it here, so i used esphome. Tuya datapoints should be similar, and if not, then it should be easily adaptable (esphome dumps most available datapoints in log).
