Background

I first started to create a script to send actions to a Google Home and resume the stream (TuneIn / Spotify) which was playing afterwards. It also restores the volume, and you can work with Google Home speakers groups.

In my home I have several Google Nest/Home speakers, and I had some scripts where a TTS would be sent which was triggered by a Google Home routine. However, I could only set it to a predefined Google Home speaker, and not to the specific speaker on which I gave the voice command.

This made me thinking, and I found a solution for this, using the ambient sounds which you can start in your routines.

So I made a new script, which can be used in cooperation with the other script, to send a TTS or other actions, like e.g. an image, or a cast of your Lovelace dashboard to specific Google Home after you ask a question to it.

As of version 2022.12 this script is included into the total Google Home Resume package

Prerequisites

  1. The Google Home Resume package needs to be installed.
  2. Expose scripts to Google Assistant (either use Nabu Casa, or the manual setup)
  3. A separate script per TTS messsage, which will be called from the Google Home
  4. A routine in the Google Home app which starts the script (you can find your scripts under Adjust Home Devices -> Adjust scenes) The last action in your routine should be to start the ambient sound (Play and control media -> Sleep sounds -> Any sound you only use for this script
  5. Define the right variables for your home in the Google Home Voice script as desribed below

Explanation of settings for the voice script

Variable Required Example Description
check_for_title Yes Witte Ruis The title of the ambient sound as shown in developer tools > states
use_resume No false Use use_resume: false if you don't have the Google Home Resume script. Don't set this setting when you do want to use it, but set it in the script call instead if you need it. Default is true.

How to use the script

To use the script you will need to provide the action to be performed. Like the Google Home Resume script only service calls are working. In case no service calls are entered the script will stop (it will only stop the ambient sound, but not resume the previous stream). There is no need to provide the target, it will be added by the Google Home Voice script, based on the ambient sound playing. In case you need to change the volume (eg for TTS) you can use the volume variable.

Example Let's say you have the Waze and proximity integrations set up, and want to send out a TTS message with the ETA.

The script will then be something like this:

eta_thefes:
  alias: "ETA TheFes"
  icon: mdi:car
  sequence:
    - variables:
        message: >
          {%- set eta = (as_timestamp(now()) + 60 * states ('sensor.thefes_home') | float(0) | timestamp_custom('%H:%M') %}
          If TheFes leaves now, he will be home at {{ eta }}.
    - alias: "TTS for speaker voice command"
      action: script.google_home_voice
      data:
        target_conversion:
          media_player.kitchen_hub: media_player.livinghome_group
        use_resume: true
        action:
          - alias: "Send TTS message"
            action: tts.google_cloud_say
            data:
              message: "{{ message }}"
        volume: 35

Variables in service call for the script:

Variable Required Description
action Yes The title of the ambient sound as shown in developer tools > states
target_conversion No A list dictonary with target replacements when you send the voice command
use_resume No Set to false in case you don't want to use the Google Home Resume script, and just want to send the actions
target_variable No If set to true the entity_id of the Google Home will be added as the variable voice_target so it can be used in scripts, and added under extra so the Google Home Resume script will resume it.
