Does anyone know of a way to be notified that a battery powered device is dead?
The battery level itself isn't a great indicator - and I don't want to change the battery until it is actually dead.
I was thinking, most if not all of my devices are constantly reporting temperature. So maybe set up some rules to test if the temperature has changed in the last 6 hours. If not, the device is likely dead.
Would anyone have a better / less hacky method?
