Configuration of motion sensor failed

Dear all,

I’m a bit confused; I’ve bought 2x IKEA TRADFRI motion sensors, but with one of them I would be able to pair it with HA. I’m using Sonoff Zigbee 3.0 USB Dongle.

During the pairing process the motion sensor will be seen, interview gets starting and finishing, but then the device will be loading during the configuration phase. If I check the motion sensor in the list of devices, it has been listed but there is no services available. I also tried to restart the configuration on the device page, but this wouldn’t work either.

The other motion sensor has been installed very easy, and is running smoothly.

Is there anyone how could help me with this annoying problemm.

Replace batteries, and pair close to the coordinator (and yes, new bought can have almost empty batteries)
