Hey Guys,

i got Openhab running with Homematic on a Virtual Machine and a CCU2 and 2 Waterdetectors, so it cant be to slow or to much devices. And I always got this error:

Hi Daniel,

I had the same problem and got it fixed by changing my openhab.cfg:

homematic:host=192.168.ccu.ccu homematic:callback.host=192.168.ccu.ccu

I thought the callback host should be my openhab server, but it works now with the same IP address as the homematic:host.

Bye,

Moritz

Hi there, did you find a solution?

did you check whether networking between the Virtual Machine and the CCU2 works?

I have the same problem. Already disabled Authentication and Firewall in Web UI, timeout has been set to 200s, but still no luck. I’d be glad to find a solution.

Openhab/Homematic Binding all at Version 1.8.2. CCU2 Firmware 2.19.9.

… if nothing helps, try restarting … in this case: restarting CCU2 => works now
