Zigbee radiator thermostat - any good ones?

Hey there,

Currently I am using homematic IP radiators, but would prefer to switch to zigbee ones.

I have observers aliexpress over the last couple of months and have seen many different zigbee radiators pop up. I bought one tuya device, but I was not really satisfied since there is a huge delay in it opening/closing the valve… It keeps it open much longer than I would prefer and opens it far too early and far too much anyway. Others have reported similar issues. In addition, the touch display to control the device manually is a joke.

I know that most other radiators are based on the tuya one, but they are often slightly different or have even different firmware.

I was wondering if anyone has bought a radiator that seems to work better and share your experience.

I am using z2m.
