How to make my Smart Home app show as a suggestion in the Google Home App

Question

When I open the Google Home app, I can see that it suggests connecting to smart home apps that I have installed on my Android or iOS device.

I'm working on an app that has a published Smart Home integration, but it does not show as a suggestion. I couldn't find any documentation on how to make it available as a suggestion like these ones on the image bellow.

Answer 1

The suggestion is what Google calls App Discovery, and there is new documentation talking about it here:
https://developers.google.com/assistant/smarthome/develop/discovery

It requires linking a website and an android app to your Smart Home Skill.
