[Cloud-to-cloud](https://developers.home.google.com/cloud-to-cloud/tools/home-graph-viewer.md.txt) [Local Home SDK](https://developers.home.google.com/cloud-to-cloud/tools/home-graph-viewer.md.txt)

The Google Home Graph Viewer is a tool to check the state of devices
in the **Home Graph** of a specific user. It obtains data from
your Home Graph and presents it to you, allowing you to verify
the data that is stored in it.

> [!NOTE]
> **Note:** You no longer need to download and deploy the [Report State Dashboard](https://github.com/actions-on-google/smart-home-dashboard/releases) to test Report State. You can test the Report State of your devices in Home Graph by using the **Home Graph
> Viewer**.

Follow the instructions below to test Report State by using the
Home Graph Viewer:

[Go to the Google Home Graph Viewer tool](https://home-testsuite.webapps.google.com/devices)

1. Sign in to Google using the top-right corner button.

   > [!IMPORTANT]
   > **Important:** Make sure you sign in with an account that is associated with the Cloud-to-cloud integration you want to test.

2. In the **Project ID** field, enter the project identifier for your
   Cloud-to-cloud integration, and click the **Sync** button:

   All of your devices are listed along with their state information. Once the
   list is populated, you can use the **Sync** button to refresh device states.
