It’s not that smart. It just sets a geofence around the location at which you programmed the device, and when you cross into or out of the geofence, it automatically activates the signal and the door operates. So, if you’re coming home and the garage door is already open, it will end up closing the door.
The “automatic” feature is something you can turn on or off. When it’s off and you cross the geofence, the control will pop onto the screen for you to tap and open/close the door manually.
Personally, I’d choose a different home automation system to solve this particular problem, I’d rather save the $300-some bucks and get a WiFi-enabled garage door opener. Then I can see from anywhere in the world whether it’s open or closed and operate/automate it using HomeKit or whatever.
