i started for 2 Weeks with HomeMatic and now with openHAB, so excuse some wordings and beginner failure :). I have binding the HomeMatic CCU2 to openHAB2 in Paper UI and got all Devices from CCU2. I have 2 Groups on CCU2 for controling window, radiator thermostat and control sensor unit for temperatur. I see this in Things and added Items for that. One Problem now is, that i cant the empty Location of the Groups. If i click on Save nothing happend and on Developer Panel i see “Error: groups undefined”. Is this an Bug, or cant i simply use HomeMatic predefined Groups in openHAB2 ?
Another point is, that i can activate the Item for Showing actual Temperature, but only see it under Control for one Group, not in the other. Same on Modes for Boost and Comfort Mode.
