How can I send a voice announcement to a Google home device via an HA alert?

[mkanet]

The below alert is set up to send a voice message to my Alexa device via my alexa notifier. However, I can’t figure out how to do the same thing with my Google Home device.

alert:
  back_door_open_warning:
    name: Back door open for 7 minutes
    message: "Please don't forget to close the back door!"
    done_message: "Thank you for closing the door"
    entity_id:  input_boolean.door_open_for_7_minutes
    state: 'on'
    repeat:
      - 4
    can_acknowledge: true
    skip_first: true
    notifiers:
      - alexa_media
      - tts.google_translate_say   #<---This line doesn't work!  Need an alternative pls.

I am able to send voice messages successfully to both Alexa and Google devices via the below automation. I just need to figure out a way to get my alert to do the same thing.

- alias: Back Door open warning
  trigger:
  - entity_id: binary_sensor.ecolink_door_window_sensor_sensor_2
    from: 'off'
    platform: state
    to: 'on'
  action:

  - data:
      entity_id: media_player.living_room_speaker
      message: Please don't forget to close the back door!
    service: tts.google_translate_say

  - data:
      target: 
        - media_player.mka_net_echo_dot
      data:
        type: announce
      message: "Please don't forget to close the back door!"
    service: notify.alexa_media

You may have noticed that the option’s name in the alert integration is called notifiers and expects to see a list of one or more notification entities. However, tts is a completely different and separate domain from notification and (as you’ve discovered) cannot be listed in notifiers.

Fortunately for you, someone has figured out how to make 'tts.google_translate_sayappear to be anotification`.

How to notify using TTS — and much more

The situation In HA, we often use notify and notify groups to alert certain situations. We have a lot of notify integrations but none for TTS. In this How-To, you’ll learn how to Use variables and inputs to set a default TTS media player and TTS language. Create a long-lived token for REST API access. Make a notify.tts_google service, as an example for simple TTS notify services. Make a versatile notify.tts service for PicoTTS, using a script. Use our new notify.tts service in an automation. …

Note
I believe the technique requires that your system is accessible from the Internet. If that’s not the case for you then it probably won’t work.

@123 Thanks for hinting at my post!
@mkanet Hope it helps!

And yes, in my configuration it requires external HA access, never tried it any other way.
