So, update.
All my devices just spontaneously became unavailable. I pressed a few buttons on a remote (Zooz 4 button) to turn different lights on and off and it just stopped working and all devices went unavailable. (Of course this was in the middle of me demonstrating the remote to my wife.) I waited a while, restarted the add on, restarted home assistant, but no luck.
At this point I’m willing to exclude everything (33 devices) and start over if that might fix the problem.
Do I uninstall and reinstall the add-on and integration? Any other steps I need to take?
Are there any logs etc. that would be helpful for me to share?
