I know this is probably an easy one for most of the members here but I’m not sure what to do.
I noticed my Multipurpose Sensor shows Inactive/Offline. I went ahead and removed it from the ST app but, as I suspected, it won’t let me add it back. It can’t find any new things. I just bought the kit on Black Friday so it’s ~2 weeks old. Surely the battery can’t be dead. It’s on my front door about 25 ft. away from the hub in straight line of sight so signal shouldn’t be an issue.
Is there anything obvious I can try before I go find a new battery?
