**Describe the bug**
Sensors become stale and not unavailable and can't be deleted

**To Reproduce**
I had issues with my UPS and have connected it to my MacBook, I got a new one and also connected that to the Macbook to check it before installing. After disconnecting, the sensors remain active and can't be deleted.

**Expected behavior**
Something should happen with these sensors, I think what other integrations do is make them unavailable, which probably makes the most sense.
In my case, I would see them deleted, if they would become unavailable I could delete them manually.

**Screenshots**

In HA the sensors remain there and look active:

After restarting the app on my Macbook, the sensors were removed from here:

The delete button isn't clickable, so can't delete them
