Google Assistant SDK

The Google Assistant SDK integration allows Home Assistant to interact with Google Assistant. If you want to use Google Assistant (for example, from your phone or Google Home device) to interact with your Home Assistant managed devices, then you want the Google Assistant integration.

This integration allows:

  • Sending text commands to Google Assistant to control devices supported by Google Assistant but not by Home Assistant. Examples:
    • Set Nest Guard to home and guarding
    • Start vacuuming
    • Stream front door on living room TV
    • Turn off kitchen TV
    • Play rain sounds on bedroom speaker
  • Broadcast messages to Google Assistant speakers and displays without interrupting music/video playback. Examples:
    • Coffee is ready
    • Someone is at the front door
    • Smoke detected in the master bedroom
    • Water leak detected in the master bathroom
  • Playback Google Assistant audio response for any query on any media player. Examples:
    • Tell me a joke
    • Say the ABC
    • Sing happy birthday
    • What does the elephant say?
  • Having a conversation with Google Assistant using the conversation integration via text or voice.


You need to configure developer credentials to allow Home Assistant to access your Google Account. These credentials are the same as the ones for Nest or Google Sheets, YouTube, and Google Mail.

Scenario 1: You already have credentials

In this case, all you need to do is enable the API:

  1. Go the Google Developers Console Google Assistant API .
  2. Confirm the project and Enable the API.
  3. Continue with the steps described in the Configuration section.

Scenario 2: You do not have credentials set up yet

In this case, you need to generate a client secret first:


To add the Google Assistant SDK integration to your Home Assistant instance, use this My button:

The integration setup will next give you instructions to enter the Application Credentials (OAuth Client ID and Client Secret) and authorize Home Assistant to access your Google Assistant API.

Enable personal results (for advanced users)

This guide shows you how to enable personal commands such as “remind me tomorrow at 9 pm to take out the trash”.

This guide is for advanced users only. It requires creating an OAuth client ID of the Desktop app, running a Python program on your desktop or laptop, copying the resulting credentials to your Home Assistant config files, and likely running an Android emulator.


  • Successfully installed the Google Assistant integration.


If you have an error with your credentials you can delete them in the Application Credentials user interface.

If commands don’t work try removing superfluous words such as “the”. E.g. “play rain sounds on bedroom speaker” instead of “play rain sounds on the bedroom speaker”.

If broadcasting doesn’t work, make sure: the speakers aren’t in do not disturb mode, the Home Assistant server is in the same network as the speakers.

The easiest way to check if the integration is working is to check My Google Activity for the issued commands and their responses.

Limitations/known issues

  • Multiple Google accounts are not supported.
  • If you see the issued commands in My Google Activity, the integration is working fine. If the commands don’t have the expected outcome, don’t open an issue in the Home Assistant Core project or the underlying library. You should instead report the issue directly to Google here. Examples of known Google Assistant API issues:
    • Media playback commands (other than play news, play podcast, play white noise, or play rain sounds) don’t work.
    • Routines don’t work.
    • Broadcast to specific rooms often doesn’t work for non-English languages.
    • Commands that need to verify your identity through voice match do not work.


On the configure page, you can set the language code of the interactions with Google Assistant. If not configured, the integration picks one based on Home Assistant’s configured language and country. Supported languages are listed here.

Service data attribute Optional Description Example
message no Message to broadcast. someone is at the front door
target yes Rooms (in Google Assistant) bedroom

Example to broadcast to all speakers:

service: notify.google_assistant_sdk
  message: time for dinner

Example to broadcast to speakers in selected rooms:

service: notify.google_assistant_sdk
  message: time for dinner
    - bedroom
    - basement

Conversation agent

You can add an assistant with the conversation agent set to “Google Assistant SDK”. See setup your assistant section here. Then you can converse with Google Assistant by tapping the Assist icon at the top right of your dashboard:

Screenshot Conversation

Or by calling the conversation.process service.

Note: due to a bug in the Google Assistant API, not all responses contain text, especially for home control commands, like turn on the lights. These will be shown as <empty response>. For those, Google Assistant responds with HTML and Home Assistant integrations are not allowed to parse HTML.
