Hey there,
I would like to replace my radiator thermostats with smart versions. But every thermostat I found has a temperature sensor built in. Since measuring the temperature right next to the radiator is BS imho, I would like to install a thermostat that is controlled via zibee (or maybe wifi or z-wave) only and does not measure the temperature or change anything on its own. It just needs to open or close the valve if told to do so by HA.
I use temperature sensors all over my place and these in combination with door and window sensors should be all I need to set up a good radiator control. The thermostat should be controllable from HA locally and directly over the protocol (zigbee, wifi, z-wave) without a bridge or cloud connection.
To clearify things: I do not want to control the heating system but just the radiators. That’s the way things work in most rental apartmens here in Germany.
Thanks in advance for any suggestions!
