Hi,
i have a pi3 with openhabian Image and installed the newest stable piVCCU ( CCU3 ). But the binding cannot find the CCU automatically. If i add the Thing manually, the gateway will be offline few minutes later. The CCU runs like a charm. I can add things and control them. If the CCU-Gateway is online in openhab, i can control the things via openhab too. but after some minutes the bridge goes offline.
Normally the binding should find the gateway autmatically souldnt it? this is the first step that dont work.
i hope you can help me
