@funeru I’m sorry to hear about the trouble with your Aqara Hub M2 after the firmware update. Let’s try to work through this step by step.
First, since the hub is online in the Aqara app but unresponsive in HomeKit, let’s focus on HomeKit-specific troubleshooting. Ensure your hub, Apple Home Hub (e.g., HomePod, Apple TV), and iOS device are connected to the same stable Wi-Fi network—a network mismatch can cause communication issues . Try restarting your router, Apple Home Hub, and the Aqara Hub M2 (unplug it for 30 seconds, then plug it back in) to refresh connections .
Next, verify if the hub has the latest firmware (check via the Aqara app under the hub’s details page). Outdated firmware can sometimes cause compatibility issues with HomeKit . If a newer version is available, update it and test again.
Since you already removed and re-added the hub to HomeKit, double-check the setup process. When re-adding, ensure you’re using the HomeKit setup code (from the hub’s bottom or manual) and follow the in-app prompts carefully. If the “Expose to Matter” option is interfering, try temporarily disabling it in the Aqara app (if possible) and re-adding the hub via the traditional HomeKit method .
If the Security System tile remains missing, check the Aqara app to confirm the security system is still configured correctly. Sometimes, firmware updates can reset automation settings, so reconfiguring the security mode automations in both the Aqara app and HomeKit might help.
Unfortunately, the reference information doesn’t specifically address the “Expose to Matter” change, but these steps are a good starting point. If they don’t resolve the issue, consider reaching out to Aqara Customer Service for further assistance—they may have additional insights into firmware-specific behavior.
Hope this helps, and let us know if you find a workaround that works!
