Contact sensor tampered

My front door contact sensor (gen 2 ) will occasionally show and send notifications of tampered. When it does, it send many in a row (17 back to back this morning). I’ve tried uninstalling, reconfiguring, resetting it, but the still come. I’m wondering if the gap is still too large between the 2 parts. I added a riser. Can a second riser be added or do they not stack? Thanks

Hi @user17933. Make sure the cover is snapped fully into place as well as making sure the Sensor and magnet are 1" or less apart from each other. You can also check out this thread here, which may be helpful depending on how you have your Contact Sensor installed.
