Voice Commands in Google Home

Google limits voice commands to “On”, “Off”, “Dim” and “Color”. If you wish to control a device that normally responds to other commands (like “Open” or “Close”), this can be done by creating and linking a virtual device to that other device and associating “On” with “Open” and “Off” with “Close”. The results might seem a little unnatural (“OK Google, turn on the garage door“), but it would work.
