Aqara M2 Gateway via Matter – Only 19 out of 26 Devices in Home Assistant

Configuration Matter/Thread
1

Hey everyone,

I’m trying to integrate my Aqara M2 Hub into Home Assistant via Matter, but I’m running into an issue. The setup works in general, and I can successfully add the Matter Bridge in Home Assistant. However, only 19 out of my 26 Aqara sensors/devices show up in Home Assistant.

What I’ve Tried So Far:

  • Updated Firmware: My Aqara M2 Hub is running the latest firmware.
  • Checked Aqara App: All 26 devices are visible and working correctly in the Aqara Home app.
  • Restarted Home Assistant: No change after multiple reboots.
  • Removed & Re-added the Matter Bridge: I reset the Matter pairing in both Aqara Home and Home Assistant, but the issue persists.
  • Checked HA Logs: No clear error messages related to the missing devices.
  • Matter Device Limit?: I’ve read that some Matter bridges have a limit of 20 devices, but I couldn’t find official confirmation for the Aqara M2 Hub.

Questions:

  • Has anyone else experienced this issue with the Aqara M2 Hub?
  • Is there a known device limit for Matter bridges in Home Assistant?
  • Any workarounds to get all 26 devices to show up?

Thanks in advance for any help!

Not all devices are bridged by Aqara, I don’t know if there’s any updated official list, they published one a while ago that might be outdated.

What are those 7 devices not visible? Maybe they’re device types not supported by the Matter version of the bridge.

I will try it now directly with a Zigbee Gateway TI CC2652P + CP2102N Device on my Raspberry Pi
