Ring Alarm
Permanently disable 2nd gen motion sensor tamper switch
While cleaning, I knocked my motion sensor off its pedestal and onto the floor. The back cover and batteries came off. Unfortunately, after putting it back together the sensor reported "possible tampering" and it wouldn't clear. The problem was the little plastic "lever" on the sensor body that the back cover "finger" pushes against broke. The physical tamper switch wasn't being toggled correctly when the back cover was in place. Bummer. As an electronics designer, I don't care for mechanical interlocks in general. An optical sensor with a little reflective tape would be what I would have used. Anyway, I removed the 4 screw covers, unscrewed the 4 screws and opened the housing. Switch SW1 is closed with the cover off and open when the cover is in place. I used a pick and gently pried SW1 off the PCB while heating the side contacts using a soldering iron. No switch, no switch contacts so it's permanently open. I reassembled it and the tamper warning is gone for good. I'm not too worried about not having the tamper feature. Hopefully the Ring app doesn't have an issue with not having the tamper switch. The motion sensor is working. Worst case, I can buy a new one for $30 (and not knock it off its pedestal onto the floor).
