Group all notifications

I want to group all my notify apps into one service

here my code

notify:
  - name: push_firestick
    platform: nfandroidtv
    host: 192.168.1.19
  - name: push_over
    platform: pushover
    api_key: removed
    user_key: removed
  - name: lannouncer
    platform: lannouncer
    host: 192.168.1.19
  - platform: kodi
    name: bedroom_kodi_notify
    port: 9091
    host: 192.168.1.19

and example to push to all notifications

  alias: away
  sequence:
    - service: notify.notify
      data:
        message: "Goodbye"

Its probably very simple but i just cant work it out

hopefully someone can help

thanks

You’re close, just missing a few things in the setup:

# Example configuration.yaml entry
notify:
  - name: NOTIFIER_NAME
    platform: group
    services:
      - service: html5
        data:
          target: "macbook"
      - service: html5_nexus
