Open question - I want to use sensors on selected windows. However, I also want some windows open for fresh air. Has anyone been able to buy just the smaller portion of the sensor (magnet)? Does anyone know if there is anything in the smaller portion of the sensor besides a magnet?
What I want is a sensor with two magnets. One placed for when the window is closed and one placed for the window to be open 12 inches. FYI - 12 inches is the max you can safely have. More than that and you can let a small burglar in.
Any small magnet will do. The better the magnet the more options are for mounting, as less quality ones may need to be mounted closer to the contact sensor unit.
Thee small piece is just a magnet in a housing.
That’s what I thought. Thanks for the confirmation.
