How to build
To connect your device with Google Assistant, you need to build a smart home Action. Assistant handles how users trigger your Action (in multiple languages) and provides you with useful metadata through Home Graph (such as the state of a specific device based on the user’s room). All you need to do is respond to the requests through your fulfillment service.
The easiest way to get started is by going through our codelabs. We recommend doing both of these codelabs, which walk you through portions of the development process, step-by-step:
After that, check our list of supported devices to ensure that what you plan to integrate is supported in the Google Home ecosystem. Then read through the Developer Checklist to understand the entire development flow from project creation to launch.
