@parisi I am just seeing this now. Did this resolve itself? I see what the issue is and will submit a code change but let me know if it is still an issue and we can try to fix it manually.

Hi @teharris1. Something happened after a recent HA update and my Insteon network (PLM-USB) stopped working. I finally resorted to resetting my PLM. Probably a dumb idea. Managed to get things sort of working by reinstalling the Insteon integration but lost all my device names, the handy Insteon left menu bar disappeared and things aren’t syncing properly (turn on light switch and HA doesn’t see that light is now on; but works the other direction).

Any suggestions on how to get this back up and running correctly? I wanted to roll back to a recent backup but it has gotten corrupted on my backup server.

Thanks!
