Aqara motion sensor triggering at night

Anyone had issues with an Aqara (PIR) Motion sensor triggering when there is no motion?

I have an automation to turn on a light using it, set so it only triggers when the sun is down. The automation used to be rock solid, but in the last month the sensor appears to trigger approx once an hour - even if there is no one in the room.

AFAIK there are nothing in the room that would be causing a temperature fluctuation this regularly - I’ve checked the temperature sensors on the server that the motion sensor is likely able to see, and there are no corresponding spikes…

And whilst when it is mis-triggering it seems to be once per hour (see 6oct midnight to 8am), the previous day it went 3.5 hours before mistriggering…

Battery is 41%, the device is connected via a xiaomi hub

me too

i have 11 sensors and 1 have this problem. it’s in the bathroom

interesting - similar trigger pattern.

some questions - I have two “sensor_motion.aq2” which don’t have this issue, and the “motion” which does have it. How about yours?
All three have similar battery level, and all three are in similar temp rooms.

hmm - I just checked. Its not had the issue for at least the last 7 days (I disabled the automation I had)

STRANGE!
