ha-alert-script

Copied from Home Assistant's Alert integration, but added data-templating and script calling. Using this as an interim until blueprints are updated to better re-create alert, and alert is deprecated. See home-assistant/home-assistant.io#28930

Features

• All features from the original Home Assistant Alert integration
• Data templating support for notifications
• Script calling on alert events
• NEW: unique_id support for better entity management

Configuration

alert_script:
  my_alert:
    name: "My Alert"
    entity_id: sensor.my_sensor
    state: "on"
    repeat: [5, 10, 30]  # minutes
    unique_id: "my_unique_alert_id"  # Optional: Set a unique ID for this alert
    notifiers:
      - mobile_app_my_phone
    message: "Alert: {{ states('sensor.my_sensor') }}"
    data:
      priority: high
    script: my_alert_script
    variables:
      sensor_name: "{{ state_attr('sensor.my_sensor', 'friendly_name') }}"

The unique_id parameter is optional and allows you to:

• Better manage entities in the Home Assistant UI
• Ensure entity persistence across configuration changes
• Enable proper entity registry management
