Home Assistant

Define one rest_command and call it from any automation: a door sensor at night, a washing machine that finished, a leak detector, a calendar event.

1. Put the token in secrets.yaml

# secrets.yaml
alarmify_authorization: "Bearer <API_TOKEN>"

2. Define the command in configuration.yaml

{% raw %}

# configuration.yaml
rest_command:
  alarmify_alarm:
    url: "https://api.signalarm.app/v1/alarms"
    method: post
    headers:
      authorization: !secret alarmify_authorization
    content_type: "application/json"
    payload: '{"fire_in": {{ fire_in | default(0) }}, "title": {{ title | default("Home Assistant") | to_json }}}'

{% endraw %}

to_json JSON-encodes the title (including the surrounding quotes), so a title containing a quote or a backslash still produces a valid request body. Restart Home Assistant (or reload the REST command integration) after editing.

3. Call it from an automation

Ring (within a minute; the API's minimum lead time is 30 seconds) when the front door opens between midnight and 6am:

# automations.yaml
- alias: "Alarm when the front door opens at night"
  triggers:
    - trigger: state
      entity_id: binary_sensor.front_door
      to: "on"
  conditions:
    - condition: time
      after: "00:00:00"
      before: "06:00:00"
  actions:
    - action: rest_command.alarmify_alarm
      data:
        fire_in: 0
        title: "Front door opened"

Ring 10 minutes after the dryer finishes, so you have time to get to it before the clothes wrinkle:

    - action: rest_command.alarmify_alarm
      data:
        fire_in: 600
        title: "Dryer finished"

Fixed time with fire_at

If you would rather send an absolute time, add a second command that takes fire_at and build it with a template:

{% raw %}

rest_command:
  alarmify_alarm_at:
    url: "https://api.signalarm.app/v1/alarms"
    method: post
    headers:
      authorization: !secret alarmify_authorization
    content_type: "application/json"
    payload: '{"fire_at": {{ fire_at | to_json }}, "title": {{ title | to_json }}}'

{% endraw %}

{% raw %}

    - action: rest_command.alarmify_alarm_at
      data:
        fire_at: "{{ (utcnow() + timedelta(minutes=30)).strftime('%Y-%m-%dT%H:%M:%SZ') }}"
        title: "Leave for the airport"

{% endraw %}
