Well there is at least one "off the shelf-ish" solution from Chamberlain's "MY-Q" system. But i'm using a z-wave garage door opener (there are tons of them that hook into most garage door openers) running off a system called "Home Assistant" which is an open-source python-3 based hub for home automation stuff. The google home can then send commands to home assistant which can do whatever i want there. So I just have a command for "open the garage door" and a command for "close the garage door" (open as well because your phone can run them as well via Google Assistant there, so I use it as an opener when I'm on my motorcycle via a bluetooth headset in my helmet) And doing it that way I can also integrate a "close garage door" command into other commands (like "i'm going to sleep" which ensures everything is locked up, or "i'm leaving" which can open it now, then close it again in 5 minutes if I forget to, or other fancy stuff like if there is no movement in the house for an hour, lock up the doors/close the garage if I forgot.)
