Controlling devices at Google Home from Homey?

You’re welcome, Senad.

Okay, my example.
Device to control: Arris TV settop box

For the OFF switch I made a similar routine.

In your particular case, you can also choose to use the Tuya cloud app tap-to-run method. A garagedoor opener is not directly supported by the app yet, but you can always make a request here.
