Out of the blue I start getting a -22% battery percentage notification. I open the app and get ready to take a screenshot and it turns to 66% (positive again). I assume it just a contact sensor glitch or bug but just wanted to know if anyone else has seen this issue or has a fix other than retire the appx 12 month old smartthings contact sensor?
Ah Ha.
I had a notification this morning that the temperature had dropped below 5 C.
Only one of 10 sensors reported.
Makes a bit more sense now.
Same thing happened to me. My Iris contact showed -33% battery and now it says 0% but it’s still sending me correct temperature reports.
No further problems occurring after this one day and the one sensor for me.
Mine eventually fixed itself and is now reporting 44% battery capacity.
