You can use Siri to open and close your garage door. Please check out this article from Apple on how to set up Siri Shortcuts. Just scroll about halfway down the article to the section on setting up Siri Shortcuts from the settings menu https://support.apple.com/en-ca/HT209055
Note that you can record any phrase you want for each shortcut. So if you want garage door 2 to open when you say "Hey this Tailwind thing is pretty cool", you can do that. The phrase is completely customizable. This is especially useful for the open commands because it's inherently more secure. Nobody can steal your phone and say "Hey Siri open garage door".
