Send picture and text to display on Google Nest Hub while sending TTS


When sending a TTS, you can only define the message, but if you have a device with a screen, it would be nice if it could display additional information while the text is being played. Especially if there are other sounds, like screaming children, loud espresso machines or drilling neighbours.


  • A dummy media player to send the TTS to. As of 2022.4 this media_player needs to work with the TTS service, because otherwise it will throw an error and the script will not continue. I’ve installed the VLC add-on on my system, and use media_player.vlc_telnet created by the VLC Telnet integration for the TTS.

Version 2.0.0/2.0.1 - 8 April 2022

:star2: Improvements

  • Really simplified this script, no need for a template sensor anymore.

:bug: Bug fixes

  • (2.0.1) Some fixes

Version 1.1.0 - 1 April 2022

:star2: Improvements

  • Simplified wait_template by removing conversion to timestamps
  • Home Assistant 2022.4 checks if an entity actually works with a service call, and throws an error if not, therefor I had to replace the Dummy Media Player with the VLC Media Player.

Version 1.0.0 - 14 March 2022

:sparkles: New feature

  • Initial post of script on Github, posted on the forum here on 17th of March


Dummy media player

Install the VLC Add on from the Add on store in the Superviser. HA should automatically find a new integration and after adding that you should have media_player.vlc_telnet
In case you don’t have the Superviser, because you use core or docker you could probably use another VLC instance to do the same.

The script itself

  alias: "Google Home - Send TTS with picture and information"
  description: Script to send a TTS with picture and text to a player with screen
  icon: mdi:cast-audio
  mode: parallel
  max: 20
    - alias: "Version number"
        version: 2.0.1
    - wait_for_trigger:
        - platform: event
          event_type: call_service
            domain: media_player
            service: play_media
              media_content_type: music
              entity_id: "{{ [ dummy_player ] }}"
    - alias: "Send TTS message with picture"
      service: media_player.play_media
        entity_id: "{{ target }}"
        media_content_id: "{{ }}"
        media_content_type: "music"
            metadataType: 3
            title: "{{ large_text }}"
            artist: "{{ small_text }}"
              - url: "{{ picture_url }}"

Place it in your scripts.yaml with a file editor (like Visual Studio Code Add-on or File Editor Add-on), not via the GUI.

How to use the script

Let’s say you want to send a message to your Google Nest Hub in the office, to announce dinner is ready, and want to add some additional text and a picture

The script will then be something like this:

  alias: "TTS with picture when dinner is ready"
  icon: mdi:food
    - alias: "Call the script with the additional data as script variables"
      service: script.turn_on
        entity_id: script.google_home_tts_screen
          dummy_player: media_player.vlc_telnet 
          target: media_player.office_hub 
          large_text: DINNER!
          small_text: Quick, before it gets cold
    - alias: "Send the TTS service call to the dummy player"
      service: tts.google_cloud_say
        entity_id: media_player.vlc_telnet
        message: Dinner is ready!

Variables in service call for the script:

Variable Required Description
dummy_player yes The dummy media_player set up for this script
target yes The target to which the TTS should be sent
message yes The TTS message
large_text yes The text to be displayed large
small_text yes The text to be displayed small
picture_url yes A full url to a picture (so no HA internal URL)

Hello, thank you for the script ! I think there is a typo in script.google_home_resume_tts_screen (should be script.google_home_tts_screen I think).

Moreover, after fixing this, I get this error : Google Home - Send TTS with picture and information: Error executing script. Unexpected error for call_service at pos 3: dictionary update sequence element #0 has length 1; 2 is required

Could you please help me ?

Sorry 'bout that, I fixed it now.

WoW it work’s perfectly now, thanks !

Do you think it’s possible to achieve the same thing but with a fullscreen picture + TSS (no text needed) ?

Not that I’m aware of, maybe with another metadata type, but I don’t know what can be used there.

Okay ! Thank you :wink:
