Link Google Assistant and Home Assistant

To link Google Assistant to the Home Assistant there are many ways: IFTTT, Google Cloud, Component. Each option will have its own advantages and disadvantages:

  • IFTTT is easy to customize according to your needs, commands and optional responses. Even the entities that Cloud does not accept, can still set up IFTTT. In return, due to the setup of each device, it will take time.
  • Home Assistant Cloud service will help you to easily synchronize devices. And an important point is that for Cloud, you don’t need any domain or SSL and still use it with Google Assistant. This is the difference.
  • Using component will be completely free but also use features like Home Assistant Cloud but setup is also lengthy.

While using a long component, it’s free, so let’s just use it. In the framework of this article, I will guide you to use google_assistant component to synchronize devices in your HASS. Let’s go !!!
