I posted this in one of the other topic areas, but thought I would repost it here where people would more mornally look . . .
If you want a functioning garage door sensor for Ring Alarm, easy and cheap, just buy a standard contact sensor and a standard door hinge. Mount the sensor to the inside of the garage door. Mount the magnet on a hinge. Mount the hinge so when the door is closed, the hinge sits flat by the sensor (door closed). When you open the door, gravity will drop the hinge mounted magnet (door open). Label the sensor as a “garage door”. Done and fully alram feature functional. And I think much more reliable long-term than those tilt sensors.
This would seem like a good opportunity for Ring . . . package a hinge mounted magnet and sell it as a garage door accessory.
