If multiple devices trigger automation, how do I know which device triggered it?

Configuration
1

Hello. Let’s have automation with multiple triggers, which is triggered when either of device A, B or C becomes unavailable. The automation triggers sending message, like "Device is not available.

How to compose message so it sends name of device that triggered the automation please?

Thanks, Jan

massage: "{{ trigger.entity_id }} is {{ trigger.to_state.state }}"

I don’t think there’s a way to do it with a single message (I’m sure somebody will correct me :roll_eyes:).

The simplest way is probably to assign an id to each trigger, then have a “choose” action with a separate message assigned to each id. For example:

alias: "[Alarm] [SMS] Smoke detected"
description: ""
trigger:
  - platform: state
    entity_id:
      - binary_sensor.nest_protect_bedroom_smoke_status
    to: "on"
    id: bedroom
  - platform: state
    entity_id:
      - binary_sensor.nest_protect_living_room_smoke_status
    to: "on"
    id: living_room
  - platform: state
    entity_id:
      - binary_sensor.nest_protect_den_smoke_status
    to: "on"
    id: study
condition: []
action:
  - choose:
      - conditions:
          - condition: trigger
            id:
              - bedroom
        sequence:
          - service: notify.tablet
            data:
              message: >-
                {{ as_timestamp(now()) | timestamp_custom('%I:%M%p', true) }}:
                Smoke detected in bedroom
              data:
                priority: normal
                device: SAMSUNG SM-T505
      - conditions:
          - condition: trigger
            id:
              - living_room
        sequence:
          - service: notify.tablet
            data:
              message: >-
                {{ as_timestamp(now()) | timestamp_custom('%I:%M%p', true) }}:
                Smoke detected in living room
              data:
                priority: normal
                device: SAMSUNG SM-T505
      - conditions:
          - condition: trigger
            id:
              - study
        sequence:
          - service: notify.tablet
            data:
              message: >-
                {{ as_timestamp(now()) | timestamp_custom('%I:%M%p', true) }}:
                Smoke detected in study
              data:
                priority: normal
                device: SAMSUNG SM-T505
    default:
      - service: script.do_nothing
        data: {}
  - service: script.all_on
    data: {}
mode: single
