False Alarm, unknown triggers

Today I had a front door entry sensor and motion sensor trigger. However, nothing could have or should have triggered them. And there's no evidence that anyone entered.  Plus, no animals, no direct sunlight, no heat/cooling.  Weird.

Hi @bk_ ,

This is definitely strange. And you said that the Entry Sensor triggered first? Since this sounds like a one-off incident, it's hard to diagnose.

But for now, I would troubleshoot each trigger separately, even if they were at the same time.

For example, Entry Sensor false alarms can be triggered at any time if the sensor loses contact with the magnet. Like if one of the pieces had accidentally been knocked off its position. Or if they were just on the border of the detection radius (of about 2"), just a little shift in the house could cause the sensor to trigger.

Or similarly, if either piece was on a metal surface (specifically iron or steel), they could demagnetize and spontaneously register as opened.

For the Motion Sensor, you're on the right track. It's triggered by heat sources moving around in the scene. Pets and heating vents are a good place to start, but you could also check for appliances like dishwashers or laser printers, where heat could suddenly appear when it wasn't there before.

Of course, we recommend reaching out to our Support team for more in-depth troubleshooting!

Sounds odd. Im assuming there wasn't any camera footage of either of the triggers? Two sensors malfunctioning or giving a false alarm at the same time seems unlikely. 

I would definitely want to confirm 100% that no one did gain access to the property. And then troubleshoot from there.
