I have a Hue Motion Sensor SML001 that was setup about a year ago.
It worked seamlessly for most of the year until recently it was undetected and no longer appeared in the Zigbee network.
The main issue seemed to be connectivity. I was using a Sonoff Zigbee 3.0 stick, but it was inserted directly in the PC I have HASSOS installed on, which is also located in a network cabinet.
To resolve this, I’ve added a 2m USB extension and placed the stick outside of the cabinet. Additionally, I’ve added an IKEA Tradfri LED controller,k which acts as a router.
This has improved the connectivity a lot, which shows in most devices and the Motion sensor also shows up again.
unfortunately, the motion sensor is now not reporting any states anymore.
I’ve tried resetting the device and removing and adding it to the network again, but to no avail.
Additionally, I’ve replaced the batteries just in case.
I’m kind of at a loss for the moment.
Any help is appreciated.
