What Brilliant supports
Brilliant currently supports the ability to allow Google Assistant to control whatever your Brilliant is directly wired to (usually lights). You can enable this by visiting Interaction Settings on your Brilliant Control, tapping the Google Assistant toggle, and then following the steps on your screen.
We do not currently have Google Assistant built-in on the Control, but this is a feature we are working with Google to add in the future.
After it is set up
If you have Brilliant in your kitchen, you can say "Hey Google, turn on the kitchen lights" to your Google Home.
