Recipe - All Sirens Go¶

Purpose¶

Notify on a critical issue by having all the sirens in the house make as much noise as possible.

Implementation¶

Use a chime delivery with a set of aliases that cope with the variety of implementations, and call it in a notification action, either on its own, or as part of a broader notification with email, mobile push etc

    - action: notify.supernotify
      data:
        message: ""
        delivery:
            chimes:
                data:
                    chime_tune: doorbell

Example Configuration¶

This config assumes that the REST commands, switches, sirens and scripts are set up elsewhere in Home Assistant.

Note that MQTT based sirens can be easily configured using MQTT Siren Integration so they can be turned on and off like any entity.

transports:
  chime:
      alias: Chimes, sirens, buzzers, doorbells and Alexa noises
      delivery_defaults:
        options:
          chime_aliases:
            red_alert:
                alexa_devices: amzn_sfx_scifi_alarm_04
                siren:
                    tune: emergency
                rest_command:
                    target: rest_command.hikvision_isapi_siren
                    data:
                        alarm_code: 11
                switch:
                    target: switch.rflink_sounder
                script:
                    target: script.ring_all_the_bells
                    data:
                      duration: 25
                      volume: 1.0

Variations¶

Use a scenario to automatically apply this delivery to any notification sent via Supernotify with priority = critical
