Just got an app notification that my front door contact sensor needs a battery change.
I didn’t have a replacement battery at hand but I have 8 brand new ones I got 5 months back as backups, so I try to uses those.
None of them worked they seen to be all dead or dying.
I did a fast run to buy a new battery to prevent this sensor from getting bricked and it worked, the sensor is now back online.
Do I need to put new batteries in the new contact sensors so they won’t get bricked when I need them in the future ?
Out of the brand new 8 contact sensors how many are or could be already bricked because of a dead or dying battery it came with ?
