What are the voice commands to control my garage door?

Google Home

"Hey Google..."

> Open the garage door
> Close the garage door

> Is my garage door closed? 
> Is my garage door open?

> Set garage door to (say percentage).

Amazon Alexa
>  “Alexa, set the garage door to 100%” - Opens the garage door

You can also customise these voice commands by creating a routine in the Alexa app then creating your own voice command for opening and closing the garage door.
