Aeotec Door/Window Sensor 7 stopped updating states - #18 by krlaframboise goes into more detail.
FWIW, I just use a normal open/close sensor on my garage door and have it mounted right at the top on the inside around the midpoint of the door. There's a small ledge above the door that the body of the sensor (monoprice in this case) site on. The magnet part is attached to the garage door. It's actually been one of the most reliable parts of my system, and is very fast in reporting if the garage door opens. The downside is that it's pretty binary - slightest bit open reports open, and it has to be fully closed to report closed. That works for me, but I understand some people like the tilt so they have a bit more discretion on how and when it reports.
I don't have anything to control actually opening or closing the garage - that's my next thing to figure out.
