Openhab2 - CCU3 - no things in inbox


I got my CCU3 visible as thing in my OpenHAB2.
The CCU3 appears as eQ3-HmIP-CCU3-App -
Attached to my CCU3 I have a temperature and humidity sensor which I can see inside the CCU3 web-UI.
But unfortunately I cannot see the sensor in the inbox of OpenHAB2.
Even not If I hit ‘scan’ - the inbox shows nothing.

How can I get my sensor available in OpenHAB2 now?

I run Openhab 2.4.0-1 on an RaspPI 3B+.
My CCU3 vewrsion is 3.41.11.

If I look at openHAB 2 Log Viewer I can see:

Thanks for any help


I could find it out. In the CCU3 ‘control panel’–>‘Configure firewall’ you have to set:

‘Remote Homematic-Script API’ to ‘Limited’
Then the actors/sensors appear in inbox on can be added as Things
