The ST arrival sensor stopped working three days ago. I thought I put in a cheapo battery two weeks ago, but no, it was a brand name Energizer. Re-pairing got it working again.
I pushed the little button for six seconds, then hit the 'start pairing' button on the discover device page, and it came up with a previously-paired device (didn't have to rename).
Does this happen once in a while? Could the battery have been loose (didn't seem to be). It's been solid for 3.5 months.
The battery has only been in for 2 weeks and it's a name brand; I got three months out of the first one.
I'm not ready yet to build a battery box for it, which I thought was for battery longevity rather than flakiness.
