It would seem to me that if you delete an integration or update a sensor, the older file should be removed. This isn’t the case in my .storage folder. I’ve got the following older files:
Are these intentionally being left behind? And is an HA issue that they aren’t being deleted?
I’ve wondered this too. Be interested if anyone knows.
I guess you could move one out of that directory and see if anything beaks? (If it does, move it back!)
I’ve deleted all but the latest before, without causing issues.
