I tried to mount the Sense contact sensor to the garage door mechanism. Due to the lubrication grease in the mechanical moving part, affixing the sensor using its own double-sided tape is not gonna cut it. And I didn’t want to drill hole anywhere to mount the sensor.
After playing around with the Sense parts, I realized that if the magnetic sensor is polarized with other metal mounting object, it would defuse the Sense senor part, so open/close sensing wouldn’t work effectively. So for now, I use these material listed below to mount it. It’s been holding up and working well. I need some advise from other users who have successfully mounted the Sense contact to the garage door nicely and still is easily removable.
1/ masking tape.
2/ wooden paint stir from Home Depot.
3/ angled plastic piece (mine from square beverage bottle).
4/ couple of binder clips.
