I am trying to swtich from my fhem installation to openHab2 (current snapshot) on a Raspberry Pi 2. I have successfully installed my HM-CFG-USB as a gateway. It is shown as a Homematic Bridge in the Paper UI. When I scan for new things my (in homegar peered) HM-CC-RT-DN thermostat is found and added as a thing.
My problem: the HM-CC-RT-DN is shown as “offline” (OFFLINE - COMMUNICATION_ERROR). Can someone give me a hint why it is offline and where I have to search for reasons etc.?
Thanks and kind regards,
