Welcome to the forum!
I use 3 of those devices to control my landscape lighting. I do not use the "switch" portion of the device at all, everything is automated via Hubitat. I think that is an "optional" feature (I am thinking of put a LV light in my tool and wood sheds, where it might be nice to have a switch. Until of course I add lux/motion/contact sensor to automate that too. Oh where does it end!! )
Also if you have an existing "switch" (mines uses a door bell device) to trigger the garage door, you could wire it in maybe?
You might also want to check out this app. It is beta, and I do not use it (I have an iris G-door opener), but read about it the other day and it might help in your instance to simplify the rule process.
