I've installed two of these several years ago and integrated them with Home Assistant. Working pretty well, no major complaints. It uses a distance sensor to determine whether or not the door is open, so it's not as reliable as state that that the garage door opener has. There was one time the distance sensor acted up and I didn't know if the door was up or down, which was annoying because I was 100 miles away. Other than that, it does what I need it to do.
