Motion sensor fall?
Just installed everything and spent the night elsewhere…get a call at 2:30 AM saying the motion sensor went off twice. In the time line it says it was triggered and then went off twice. I disarm it, not seeing that a door was open (windows are locked and have a sensor outside). I only stuck the motion sensors up so no screws. After disarming the sensor almost immediately goes off again. Would it keep going off if it fell face down?

Hi @hcushing7,
A Motion Sensor falling off the wall could trigger a false alarm; but if it fell off once and triggered an alarm, it shouldn't trigger another one.
Do you have any pets that may have been able to get close to the Motion Sensor and set it off? Pets under 60 pounds generally shouldn't trigger the Motion Sensor, but if a small dog or cat was able to get close enough, they could trigger an alarm.
The Motion Sensor uses a passive infrared sensor to detect sources of heat moving around. So if the Motion Sensor is placed near a heating vent or AC and they kicked on, suddenly changing the temperature in the room, that could have triggered a false alarm as well.
To learn more about what could cause the Motion Sensor to trigger a false alarm, and how to prevent additional false alarms in the future, check out the Motion Sensor Gen 2 False Alarms article in our Help Center.

@hcushing7 When you get back in town, suggest the following:
1. Change all motions to "secret alert" for home mode.
2. Arm system to home mode.
3. Sit in an area not covered by motions and see if it sends you a message, whether test or push, depending how your app is set up.
4. if you get an alert, disarm the system and exchange the motion that went off with another one (swap locations)
Repeat above.
If the original motion sensor goes off in the new location (Secret alert) you have a defective motion unit, call tech support, tell them what you did and ask it to be replaced.
If the other sensor, the one you swapped out, now goes off in the same original location , you now have isolated the issue from the device being bad, and its a location issue. (Some type of heat source, cooling/heating duct, sun through window, ceiling fan etc.
BTW, what did you mean by "a sensor outside"?
