I have the same problem, but with Fibaro FGS222 and posted a question about that recently
(here)
I have another problem that might be related, it’s remote controls and Fibaro Dimmer2, associating my remotes to trigger the dimmer2 does not work after making a fresh openhab install. (here)
I have no solution for you, I got some help from @chris and i’m waiting for him to hopefully get back to me. Perhaps we can help each other in some way?
Do you have Fibaro dimmer2:s also?
