I’ll look into it as well. Thx
Well, I have not upgraded to 0.86.x yet, but I did try the add-on. It did not find any issues.
Then I decided to try and scan for the dread double underscore.
I logged in and went to the /config directory and ran:
grep -l “__” *.yaml
Sure enough, I had references to a set of binary sensors with double underscores in them in my groups.yaml and ui-lovelace.yaml files. There are also references in the db, so I plan to delete and re-create that.
