  - data:
      topic: zigbee2mqtt/[Your HS2WD Name]/set
      payload: |
        {
          "warning": {
            "mode": "emergency",
            "strobe": true,
            "duration": 1
          }
        }
    action: mqtt.publish

The siren can also be stopped again with "mode": "stop".

Warning: In the example code, the duration is set to one second. The device is extremely loud. When testing, it's best to cover the speaker at the front with your hand.
