i don’t suppose you can just order the magnet to the multipurpose sensor. it fell off one of my doors and is lost now
Any magnet will do or you could get something like this, convert one of the sensors to a water detector which doesn’t need the magnet. For the price, you’ll get a spare contact sensor plus a motion detector.
Or put your request here and maybe somebody with lots of extra magnets won’t mind sending you one for a beer maybe
Search Ebay/Amazon for alarm magnet and pick one. You’ll only use the magnet side.
Thanks, did not even think to search on just magnet. Got one.
