Aqara FP300 Configuration

I have recently purchased a FP300 to see if it's worth replacing my existing PIR sensors. I have managed to get it setup with Zigbee2MQTT, but looking for help with getting the settings right.

Also the battery still hasn't reported, I've had it running for a week now. Most other devices take about 24hrs to report their battery level.

Any pointers would be very much appreciated.

Thanks

Garry
