Homematic rollershutter loses pairing

Hi everybody,

I’m using the HM-MOD-RPI-PCB on my Raspberry to control a couple of Homematic rollershutter actors HM-LC-Bl1PBU-FM. Everything is working fine with out any problems.

One of the actors is loosing the pairing from time to time. I can pair the actor again without any problems. Then it’s working again for a couple of weeks. The actor is the one that is the closest to the HM-MOD-RPI-PCB (about 5 meters) so I don’t think signal strength is an issue.

Is there a way that I could troubleshoot this behaviour? Are there any logs I could check?

Thank for your support.
