Zigbee2mqtt with ikea tradfri motion sensor phantom triggers

Tags: #<Tag:0x00007f326ef5fc38>

I’ve been having issues with my tradfri motion sensors triggering by them self.
My only theory is that maybe they loose connection and when they reconnect they update status resulting in HA thinking they triggered ? Any ideas ?

I’m having the same problem, but with ZHA.
Logs seem like a normal motion detection:

Same for me, also with ZHA and deconz stick. No ideea what triggers the sensor. I have the original battery and it’s 47%.
What is your battery level?

Hello to everyone!!!
