I can see the problem’s cause in your things file. callbackHost and gatewayAddress are the same. this is probably wrong. gatewayAddress is the address of the CCU and callbackHosts is the IP address of the Raspi where OH is running. If the raspi only has got one IP address, you can omit this setting.
Embarrising considering how much time I spent reading the binding deatils and checking the community… ( cannot see the wood for the trees) - thank you for the hint, works now!!!
I am still wondering about the ccu2 to be detected: HmGatewayInfo[id=CCU,type=CCU2,firmware=3.61.7.20220115,address=xxx,rf=true,wired=false,hmip=true,cuxd=true,group=true]
Good to hear that I could help and that it’s working now.
The APIs of the CCU2 and CCU3 are identical. That’s why the type is CCU2. I’m also not sure if the binding could distinguish the two types at all.
Good to know, thanks!
