Paring Aqara P1


i have two Aqara P1 and want to pair these with my Phoscon System.
The first one paired after a view trys. But its impossible to pair the second one.
I press in the Phoscon App pair a new Sensor, press and hold the button on the Sensor while the LED flashes, but without success.

Have anybody an idea?

System info:
Raspberry Pi 3 with Phoscon SD Image 2.24.2
ConBee III

Thanks and regards
