This is probably the biggest thing I HATE about the companion app. If you log out for one reason or another, Home Assistant sees it AS A NEW DEVICE and you have to reconfigure all of the sensors over again.
I was cleaning up my login history today and removed the phone login in error which is why I am writing this. Is there a possible workaround for this?
I can see why it is annoying and I do not have an answer for you.
But out of curiosity: why would you log out on the companion app? I never felt the need, and if I do feel the need to log in as another user I do so in the browser. So without intending to sound like s smart ass, avoiding the problem is the best I can think of. But maybe I miss why you’d need to.
Another thing: if the device were to be hard linked and persistent to the device, how would HA respond if another user is now linked to the same mobile device?
ps. Andoid phones can login as another user. Could that be a workaround?
I made a mistake logging it out. I had to recreate my widgets as well which was a pain but that is generally only the reason why. I suppose I could always just do a Copy Paste in to my phone’s clipboard from KDE to the app with a long term access code. But, this is one of those days where I was caught by surprise!
If the Home Assistant app is hard linked to the device, I would think you could always disable it from the device list in Home Assistant.
