Communication issue HG-HM-LC-Sw4-WM - No answer from device

Hi,

I am looking for hints on how I could fix the below described issue that I face with a Homematic HG-HM-LC-Sw4-WM that a lately installed. I have two other Homematic devices in my environment that work properly. The new device is not working properly and when I check the logs I see that there is some kind of communication issue (na answer from device). What I did so far:

Removed the thing and added the thing again.
update/upgrade openHAB
reinstalled homegear
updated homegear

Nothing helped. So I set the debug level for Homematic to DEBUG. As I am not able to interpret the log myself it would be great if someone could give me a hint.

My environment:
Openhab = openHAB 2.4.0-1 (Release Build)
Homegear = 0.7.39-2773
Release = Raspbian GNU/Linux 8 (jessie)
Kernel = Linux 4.9.35-v7+
Platform = Raspberry Pi 3 Model B Rev 1.2
Wireless Module for Homematic = HM-MOD-RPI-PCB
