The little bb in those has been known to get stuck in one position. The solution is soldering in a mercury one. About $1.89
@mavrrick58 @rlithgow1 changed the CR2032 batteries , opened and closed the door , problem solved! I assumed it wasn't the batteries because I had changed it barely 6 months ago. Seems to be going through batteries quick. But the other garage door with same sensor doesn't do that.
Yeah. I also don't trust the battery level indication. When I first installed it, for the first month it was all over the place. From 100 to 1 in less than 24 hours, then back to 98. It took it about A month to settle down. I think now it is finally legit low. If so that works be about 10.5 months on one battery.
The real solution would be for the sensor to be reliable the lack of reliability drives me insane. Where did you buy this mercury goodness ?
you can get them anywhere including amazon. Newer versions of the sensor use a gyroscope...
