Tradfri, false motion detection alert

Configuration Zigbee
1

Hi there,
during last months I observed some false motion detection alerts from my Ikea Tradfri sensor, apparently triggered without any moviment.
The sensor has been working fine since then, it’s installed over the door of a windowless boxroom - I’m pretty sure it’s not triggered by insects. On the other hand, when a person enter the room everything works as expected.

Some info about the scenario:

  • Motion sensor firmware: 0x20022623
  • Integration with HomeAssistant ZHA (Conbee II USB key)
  • Core: 2021.7.4
  • Supervisor: 2021.6.8

Does anyone suffer from the same issues?
Thanks for any tip.

Its only recently (2 ish months) this has started occurring.

I am also using a Conbee II

I replaced it with ESP Lolin32 + AM312 PIR sensor.
Very happy so far.
