The Google Assistant component requires a bit more setup than most due to the way Google requires Assistant Apps to be set up.
<p class='note'>
To use Google Assistant your Home Assistant configuration has to be externally accessible, with a hostname and SSL certificate. If you haven't already configured that you should do so before continuing.

- **project_id** (*Required*): Project ID from the Google Developer console (looks like `words-2ab12`)
- **client_id** (*Required*): A long random URL safe string (no spaces or special characters) that will be used for Implicit OAuth.
- **access_token** (*Required*): Another different long random URL safe string.
- **agent_user_id** (*Optional*): A string to identify the user, e.g., email address. If not provided, the component will generate one.
- **api_key** (*Optional*): An API Key generated for the project from [Google Console](https://console.cloud.google.com/apis/api/homegraph.googleapis.com/overview) which allows you to update devices without unlinking and relinking an account (see setup below). If not provided then the request_sync service is not exposed.
- **exposed_domains** (*Optional*): An array of Home Assistant domains to expose to Google Assistant. Options include:
- `switch`

It's very important that you use very long strings for `client_id` and `access_token`. Those are essentially the credentials to your Home Assistant instance. You can generate them with the following command:

If you're not using Linux, you can use sites such as [this one](https://www.browserling.com/tools/random-string) to generate a random string (containing mixed case letters and numbers) of up to 80 characters.
You can also customize your devices similar to other components by adding keys to entities:
```yaml
homeassistant:
customize:
master_bedroom_light:
google_assistant: true
google_assistant_name: bedroom light
bedroom_blinds:
aliases:
- bedroom shades
- bedroom covers
hallway_ceiling_switch:
google_assistant: true
google_assistant_type: light
```
Entity Customization Keys:
- **google_assistant**: True exposes entity, false will hide it.
- **google_assistant_name**: Can be used to override the primary name of an entity. By default the `friendly_name` of an entity is used.
- **google_assistant_type**: Can be used to override the domain/type of an entity. For example a switch can be treated as a light
- **aliases**: Provides "nicknames" to Google Assistant. These function as alternate names for an entity that Assistant will understand when spoken.

*Note:* The request_sync service requires that the initial sync from Google includes the agent_user_id. If not, the service will log an error that reads something like "Request contains an invalid argument". If this happens, then [unlink the account](https://support.google.com/googlehome/answer/7506443?hl=en-GB) from Home Control and relink.
### {% linkable_title Troubleshooting the request_sync service %}
*Note:* The request_sync service may fail with a 404 if the project_id of the Homegraph API differs from the project_id of the Actions SDK found in the preferences of your project on [developer console](https://console.actions.google.com). Resolve this by:
1. Removing your project on the [developer console](https://console.actions.google.com).
2. Add a new project in the [cloud console](https://console.cloud.google.com). Here you get a new project_id.
3. Enable Homegraph API to the new project.
4. Generete a new API key.
5. Again create a new project in the [developer console](https://console.actions.google.com/). Described above. But at the step 'Build under the Actions SDK box' choose your newly created project. By this they share the same project_id.
