I own 6 Tuya GTZ02 TPVs (https://www.zigbee2mqtt.io/devices/GS361A-H04.html) of various brands.
Registering them in my Zigbee gateway was a no-brainer. The time zone is correct. The manual temperature control is ok.
The issue is the automatic control (scheduler) which does not work. The TPV display turns on at saved times, i.e. something is triggered. However the valve motor does not start.
I made a full reset and recalibration but it had no effect. In the manual mode the radiator is cold when the TPV is set to 5°C, so the calibration is correct. The automatic mode is certainly active.
I checked out various Tuya compatible apps but they are only different brandings for the same cloud, as far as I can see.
It is improbable that all 6 TPVs are broken. What could be the reason of my problem?
