Just got a motion sensor stopped working all of a sudden. Thankfully the device heath warned me about it.
I see the battery still is 100% before the moment the device drop out, but I replaced it anyway, since it is in a quite busy zone I would expect battery to be dead very soon.
Turns out the problem is the battery.
If the battery percentage report cannot be reliable due to the small form factor can we have something like “last battery replacement 100 days ago”?
