I had issues with my project and starting fresh seemed to fix it.
- Pull the new container image version
- Recreate the Google Actions Project following googles new documentation https://developers.google.com/assistant/sdk/guides/service/python
- Once setup, authenticated and showing up in Google Assistant settings on my phone I had to join the new device to my home in the Google Home app. Then it picked up on my Device Address for broadcasts.
This is a emulated Google Assistant with a webserver attached to take commands over HTTP packaged in a Docker container. The container consists of the Google Assistant SDK, python scripts that provide the Flask REST API / OAuth authentication and modifications that base it from the Google Assistant library.
I did not write this code, I simply pulled pieces and modified them to work together. AndBobsYourUncle wrote Google Assistant webserver Hassio add-on which this is largely based on. Chocomega provided the modifications that based it off the Google Assistant libraries.
How does this differ from AndBobsYourUncle's Google Assistant Webserver? This project is modified, running based on the Google Assistant libraries not the Google Assistant Service which allows for additional functionality such as remote media casting (Casting Spotify) See the table here. However this method requires a mic and speaker audio device or an emulated dummy on the host machine.

- Prerequisite - Mic and speaker audio device configured on the host machine. Michal_Ciemiega pointed out that a real soundcard is not necessary with:
sudo modprobe snd-dummy. If you're not sure or need help you can follow Googles Configure and Test the Audio documentation.
- Go the Configure a Developer Project and Account Settings page of the Embed the Google Assistant procedure in the Library docs.
- Follow the steps through to Register the Device Model and take note of the project id and the device model id.
- Download OAuth 2.0 Credentials file, rename it to
client_secret.json, create a configuration directory/home/$USER/docker/config/gawebserver/configand move the file there. - Create an additional folder
/home/$USER/docker/config/gawebserver/assistantthe Google Assistant SDK will cache files here that need to persist through container recreation. - In a Docker configuration below, fill out the
DEVICE_MODEL_IDandPROJECT_IDenvironment variables with the values from previous steps. Lastly change the volume to mount your config and assistant directories to/configand/root/.config/google-assistant-library/assistant
- Start the container using Docker Run or Docker Compose. It will start listening on ports 9324 and 5000. Browse to the container on port 9324 (
http://containerip:9324) where you will see Get token from google: Authentication. - Follow the URL, authenticate with Google, return the string from Google to the container web page and click connect. The page will error out and that is normal, the container is now up and running.
- To get broadcast messages working an address needs to be set, the same as your other broadcast devices. In the Google Home app go to Account > Settings > Assistant. At the bottom select your ga-webserver and set the applicable address. There you can also set the default audio and video casting devices.

Not sure why a command isn't working? See what happened in your Google Account Activity or under My Activity in the Google Home App.
Here is an example how I use the ga-webserver in Home Assistant to broadcast over my Google Assistants when my dishwasher has finished.
notify:
- name: ga_broadcast
platform: rest
resource: http://containerip:5000/broadcast_message
- name: ga_command
platform: rest
resource: http://containerip:5000/command - alias: Broadcast the dishwasher has finished
initial_state: True
trigger:
- platform: state
entity_id: input_select.dishwasher_status
to: 'Off'
action:
- service: notify.ga_broadcast
data:
message: "The Dishwasher has finished."My Home Assistant Configuration repository.
- There are duplicate devices in the Google Home app - This happens every time the container is recreated, it looses its
device_idstored in the container. This is fixed with my add step 4 under Setup. Once the container stores its newdevice_idthere it will persist through container recreation. - Error: UnicodeEncodeError: 'ascii' codec can't encode character - zewelor discovered this issue of a Wrong UTF8 encoding setting in the locale env. He solved this by adding the environment variable
PYTHONIOENCODING=utf-8to the Docker configuration. - If it was working and then all the sudden stopped then you may need to re-authenticate. Stop the container, delete the
access_token.jsonfile from the configuration directory, repeat the First Run procedure above. - Having other problems? Check the container logs:
