You guys all read the FAQ right?
I have a bunch of these sensors on order. I have mostly wood door frames but the exterior ones are metal. I’ll be watching this carefully…
- the following problem is specific to magnetic devices. If there is a piece of metal nearby, including a metal window frame, a metal door, sometimes even a metal switch plate, the magnet can magnetize that piece of metal, and then The sensor gets very confused. there are a couple of forum topics on this. If this is the problem, it will take a while to fix because it takes a week or two for the other metal to lose its charge. But this is one of the first things the field tech will look for if a sensor works just fine for a few days or a week and then gets stuck.
