Popp thermostatt


i have integrated Popp Thermostat zigbee, but they work mostly in manual mode. when i change the temperature its synced to the device in few seconds, i can see the change of heating temperature on the device but the heating is not turned on. nothing happens, just few click type sound from the device, but if i set the temperature manually directly on device, heating is turned on immediately.

i have tried from web interface as well as android app. same result. sometimes it works, most of the time it doesn’t respond to app.

i am using smartthings hub v3.
