This sample contains a fully functioning example of a Smart Home provider cloud service. This sample is intended to be used together with a Smart Home project you create in the Actions console, to demonstrate how to integrate smart devices with the Google Assistant.

This sample includes the following features to help you get started:

• Fulfillment backend for Smart Home Action.
• Mocked user authentication backend which comes prepopulated with sample users.
• Web frontend with an interactive experience for users to control smart devices.

See the developer guide and release notes at https://developers.google.com/assistant for more details.

Clone the project and the included frontend as a subdirectory:

git clone https://github.com/actions-on-google/smart-home-java.git
cd smart-home-java
git clone https://github.com/actions-on-google/smart-home-frontend.git

1. Use the Actions console to add a new project with a name of your choosing and click Create Project.
2. Select Home Control, then click Smart Home.

1. From the top menu under Develop, click Invocation.
2. Add your Action's name. Click Save.
3. From the top menu under DEPLOY, click Directory Information.
4. Add your Action info, including images, a contact email, and privacy policy. This information can all be edited before submitting for review.
5. Click Save.

The Request Sync feature allows your cloud integration to send a request to Home Graph to send a new SYNC request. The Report State feature allows your cloud integration to proactively provide the current state of devices to Home Graph without a QUERY request.

1. Navigate to the Google Cloud Console API Manager for your project ID.
2. Enable the HomeGraph API.
3. Navigate to the Google Cloud Console API & Services page.
4. Select Create Credentials and create a Service account key.
   1. Create a new Service account.
   2. Use the role Service Account > Service Account Token Creator.
5. Create the account and download a JSON file. Save this as src/main/resources/smart-home-key.json.

1. Open your project in the Firebase console
2. Select a Cloud Firestore database.
3. Configure a users collection with a default user and a few default fields

    users\
        1234
            fakeAccessToken: "123access"
            fakeRefreshToken: "123refresh"
            homegraph: false

Note: If you are not using Google App Engine to host your server, but still want to integrate with Firestore:

• Set the GOOGLE_CLOUD_PROJECT environment variable to the name of the Firebase project.
• Read this guide on setting up the Firebase Admin SDK.
