I recently bought three FP300 multi-sensors, replacing FP2s. I installed them on Nov 25 and added them as Thread/Matter devices to an Aqara M3 hub as well as Home Assistant.
This worked fine for a while until one by one went offline. Their last online dates are Dec 6 13:04, Dec 8 21:32, Dec 8 21:34. Since then, the Aqara app and HA show them as offline and automations are not working. I‘ve restarted the M3, but that didn‘t help.
I have 42 Matter devices at home, most of them using Thread. All are working fine except the FP300 (including other Aqara products like G410 or E1). They are using plugin version 0.9.4.
I have not yet removed their batteries as they are hard to reach, but I also think that should not be necessary.
Any idea what is wrong?

I saw that thread, but the symptom here is different. My sensors went fully offline, not stuck in “presence”.
I have a quick update to share. Support suspected this: “When bound to multiple platforms, there may be a situation where the battery drains quickly.” They asked me replace batteries (after a few days, not the advertised 2 years in Thread mode). As I didn’t have CR2450 around, I just removed the batteries and re-inserted them. This brought them back to life and HA reports 100% battery state…
However, not all three sensors behave identically now. 2 out of 3 are “online” both in the Aqara ecosystem as well as in Home Assistant. The third sensor is still “offline” in the Aqara app, but the app happily shows new events in the log as they occur when people enter or leave the room - the sensor is reachable from HA and automations work.
I suspect an issue with the multi fabric implementation. Which is surprising because I have several other Aqara Thread devices connected to multiple fabrics without this issue.

I understand that, if they release new firmware hopefully it helps both of us.

After resetting all sensors, they were working fine for two weeks. Now, the same issue is back and they‘re again offline…
