Homematic IP wall switch only sending "UNREACH"

Hi,

I tried to integrate the HMIP-WRC6 via the CCU.

I only ever seem to receive the UNREACH event whenever I push a button:

10:03:51.788 [TRACE] [rnal.communicator.server.XmlRpcServer] - Server parsed XmlRpcMessage:
system.multicall()

        {
                methodName=event
                params=
                [
                        HMIP-09319ca3
                        000B57099511A9:0
                        UNREACH
                        false
                ]
        }
        {
                methodName=event
                params=
                [
                        HMIP-09319ca3
                        000B57099511A9:0
                        RSSI_DEVICE
                        -69
                ]
        }
]

Native Homematic devices are sent and received correctly.
I already created the file services/homematic.cfg containing:

homematicIP.enabled = true

After trying for 2 days now, I seem to be out of ideas on how to solve this…

I think I solved it now…

It seems that the CCU does not send HMIP events it doesn’t see as ‘used’. Creating a program in the WebUI which does effectively nothing but uses the buttons as triggers solved the issue:
