Beginners guide for implementing Eltako FSR14, FSB14, FUD14 via FGW14

I just came home from 8 days of vacation, with @rlkoshak’s Presence Simulation [4.0.0.0;4.9.9.9] active. But I noticed upon arrival the OH items didn’t record the input from the physical switches anymore. Also, in the CLI log, nothing appeared when I switched the physical switches. (The OH switches worked, and switched the lights as they should.)

After a reboot, all works again, but I assume something broke down along the way?

Are there any logs I can try to find? I’ve got 7 days of back-up if need be…
