Also it is giving me th eerrorcode E5 on the display - it means “The termostat is not receiving the expected replies form the control system. Check tat you have a Z-wave certified controller rnning and it has the necessary functionality to control the thermostat”. Can I change the XML-file somehow?
Maybe it’s not included into the network properly, or is out of range of the controller? You could try getting a debug log to see what communications is going on between the OH and the device (although I suspect none based on the error).
Can you remember something you have done? I have the same issue with this Popp Tmermostatic Valve, after a while getting E5. When waking it up manually by pushing the middle button, I’m able to change setpoint and receive the temperature, but after a while getting E5 in display and can not change the setpoint. Seems to be a weakup thing. I tried to exclude it and include it with Zwave.Me instead of Habmin, but same result.
Would appreciate any hints.
