So, long story short I was given a Craftsman Garage door monitor. I thought "How frivolous is this???" Then I began using it, sensor on the door, monitor in the bedroom. I now go to sleep and look at the monitor one last time to ensure my better half, or I, didn't "forget" to close the garage door. I can't tell you how many times I got BACK up out of just getting into bed to check the door because my wife couldn't answer the question "Did you close the garage door when you came home tonight?" I MEAN COME ON!!!! It's not like I have anything in there!!!
It's not the best solution but for $35 +/- you can't beat the peace of mind. (Electro-geeks..... go nuts. I know of at least 3 major sirens I can trigger off this little LED....
)
Here's how it works. A gravity sensor is mounted to your garage door via double sided tape and velcro. When closed the sensor is "open", when the door is open the sensor is "closed" thus sending a signal to the monitor that flashes an LED. SUPER simple and a great idea. Worth $35?? No, but sure is easy to install!!!

THIS IS NOT GARAGE DOOR OPENER SPECIFIC!!

Quite disconcerting at 2 in the morning.
You are a very patient man.
