Those are improved “P1”. Not “P2”, do not support Matter.

Yes, of course ... I will correct my post above.

Ah, 2022. Impressive.
@dnickel I am almost sure now that there is a bug in the "Aqara P1 Motion Sensor" driver that affects the battery voltage decoding of Aqara RTCGQ11LM (lumi.sensor_motion.aq2) motion sensor. I will change the simple decoding with a more complex TLV algorithm in the next driver update.
This bug is more than two years old, and it's a mystery for me how it has gone unnoticed for so long...
I'm like a bad penny, I just show up when you least expect me.

Just to mess with you some more. 
I find my test subject, with the full, tested battery, cycling On and Offline.It seems to happen every time the battery reports in.
I'll quietly walk away now.

@dnickel please update manually the "Aqara P1 Motion Sensor" driver ( version 1.9.1 2025/11/12 7:45 AM).
- Bug fix: decoding Aqara RTCGQ11LM (lumi.sensor_motion.aq2) battery voltage
My four RTCGQ11LM are now showing correctly battery voltages 3.075, 3.015, 3.075, 3.035 V
Under test. Thanks!
Events/Logs are broken in latest beta so I'll just have to keep checking for a bit to see what Statius says.
I went back to .153 to get Events/Logs.
Well done. I have one 78% left.
The rest are between 2.97 and 3.325 (test motion) at 100%

Just a query and another thanks for fixing this. 
I have had a few motions go Offline and it was the battery.
I'm just wondering if the battery scale is a bit too aggressive toward the 100%?
The last 3 battery changes all report 100% at 3.025 VDC but they were indeed dying.
A good battery is 100% at 3.235ish.
Can this VDC interpretation be softened toward the <100% at 3.025?
What do you find? Do your motions still function at < 3VDC?
Improving the battery voltage-to-percentage conversion is on my to-do list, but I need to finish my TRV project first. After that, I can revisit this topic. The idea was to implement a better linearisation algorithm. Currently, the range is 2.5V...3.0V for the Aqara motion sensors and 2.85V..3.0V for FP300. Perhaps the lower threshold of 2.5V is too low; I can use the 2.85V minimum for all Aqara sensors.
After working reliably for several years, two of my RTCGQ01LM started to disconnect from my Zigbee network in the past few months .. 
The last battery voltages reported are 3.015 and 3.065. I think the battery voltage is not the problem in my case. I can prove this by moving these two motion sensors to my Aqara M3 hub and bringing them back in HE via the Matter Bridge.. I can do this quickly this weekend.

Hey, no worries. Just thought I would plant a seed.
My other sensors seem ok. Just replaced a water sensor battery and it failed at 78% which was perfect.
