A solution we found for a customer involved creating a Smart Life scene that controls a Wi-Fi plug (compatible with the Smart Life app). When the alarm is triggered, the scene turns the plug on—activating the siren. Once the alarm panel is disarmed, a second scene turns the plug off, silencing the siren.

You would first add the outdoor plug to the Smart Life app and then create the scenes as described above.

The siren links above is an example of a 120V high-decibel, high-power outdoor alarm siren. You are not limited to this specific model—you may choose and source your own outdoor siren as long as it meets your needs and is compatible with the Wi-Fi plug.
If you choose to use a 12V siren instead of a 120V one, you will also need to purchase a compatible 12V outdoor power transformer to connect it to the Wi-Fi plug and ensure it operates correctly.
