Use IP cameras to watch the garage door. A little Blink camera at the back of the garage will tell you if the door is open. There are IP devices that connect to garage door openers via two-wire and can be controlled via an app. The only thing about remote operation is that you're not present to ensure the door is clear of obstruction, and you're out of luck if the power/data goes down.
