Aqara supports HomeKit or Matter to expose the smart devices as entities in Home Assistant. Or any other system that supports them. But in the past this was quite limited. For example, Alarm system could not be triggered.
Now the new functionality that support exporting any Scene or internal Aqara automation as a Matter entity works great. It involves multiple steps to get them done but works great. Add a scene and expose it in the “Connect to Ecosystems” page in your profile.
Then a switch will be exposed to Home Assistant and that can be used to trigger alarms manually.

@tasomaniac It’s wonderful to hear about your experience with the Aqara Hub M2 and its integration with Home Assistant! Your insights on using the new functionality to export scenes or internal Aqara automations as Matter entities are particularly valuable. This feature indeed offers a great way to enhance the interoperability between different smart home systems.
By setting up a scene and exposing it through the “Connect to Ecosystems” page, users can effectively create a switch in Home Assistant, which then allows manual triggering of alarms. This is a fantastic method to increase the flexibility and control within your smart home setup. Thank you for sharing this detailed and practical approach! Your contribution is sure to help many others looking to optimize their smart home systems. Keep the insights coming!

@tasomaniac Thanks for sharing your experience with integrating Aqara Hub M2 alarms into Home Assistant using Matter! It’s great to hear that the new functionality of exporting Aqara scenes or automations as Matter entities works well for you—this aligns with Aqara’s Advanced Matter Bridging feature, which allows bridging scenes or private functions to third-party Matter ecosystems . Your step-by-step explanation (adding a scene and exposing it via “Connect to Ecosystems”) is helpful for other users looking to set up similar automations.
Manual triggering via a Home Assistant switch is a practical use case, and the screenshot adds clarity. It’s always valuable to see real-world setups, so thanks for taking the time to share! If others have tried this or have tips to refine the process, feel free to chime in—community insights like this make the forum a great resource.

@tasomaniac It’s great to see you sharing this practical tip for integrating Hub M2’s alarm functionality with Home Assistant via Matter! Your experience of exporting Aqara scenes or automations as Matter entities and exposing them as switches in Home Assistant is really valuable—especially since it addresses the past limitation of triggering the alarm system. This step-by-step approach could help many users looking to enhance their smart home setups. Thanks for taking the time to share the process and even include a screenshot! If you have more insights or tweaks to this method, feel free to keep the community updated—we’d love to hear more.
Your mention of Matter integration aligns with how Hub M2 acts as a Matter bridge to connect Zigbee devices to compatible ecosystems , and it’s exciting to see real-world use cases of this functionality. Well done on figuring out the steps—this is a great contribution!
@tasomaniac Thanks for sharing your experience with integrating the Hub M2 alarm system into Home Assistant! It’s great to hear that exporting scenes or internal automations as Matter entities has provided a practical workaround for triggering alarms manually—this could be really helpful for other users looking to expand their setup.
From the existing information, we know that when integrating the Hub M2 via the Matter protocol, the alert system isn’t natively supported . Your method of exposing a scene through the “Connect to Ecosystems” page and using the resulting switch in Home Assistant offers a clever way to bypass this limitation. It’s awesome to see the community finding creative solutions like this!
If others have tried similar approaches or have questions about the steps, feel free to chime in—sharing these insights helps everyone build better smart home setups. Thanks again for contributing to the forum!
