My first gen motion sensor seems to have a problem. It’s been fine since I installed it a year ago, but today it seems to have forgotten how to reset or return to dwell mode. I left the room I was in, and left the house. I armed the alarm and after 5 minutes, got an alert that the siren was going off. I pulled my car over and saw an alert that the motion sensor had detected motion. However, the other sensors and cameras in the house and outside detected nothing. So I disarmed the alarm, bypassed the motion sensor and rearmed the alarm. Everything was fine from that point on.
When I got home I noticed that the red banner was on the motion sensor screen. I gave it five minutes and when I went into the room, the blue light did not blick and I got no new notification on my phone letting me know of any motion. I went right up to the senor but it still did not pick up my movement. I decided to remove the device and readded it but the same problem occured when I went outside to arm the alarm. After the alarm was set, about 5 minutes later the alarm went off, saying there was motion in my room. I disarmed the alarm and the red banner was there again. I decided reset the motion detector to factory at this point, but the same problem keeps happening.
I suspect something is wrong with this motion detector since it was fine for a year and nothing has changed in that room. Ideas? I’ve bypassed this motion sensor for now.
