My wife had an irritating habit of leaving the garage door open when I was on a trip. That could have ended up being fairly..... expensive since I have a lot of spendy toys there.

This was the solution, as I have a Chamberlain opener: https:https://www.walmart.com/ip/CHAMBERLA...ll&athena=true

It works a treat-- I put it in the bedroom, and if the garage is open, you get a red light and an occasional "chirp". Push the button, and it closes and the light turns green.

Problem solved.

Additionally, the Chamberlain opener has an iPhone app that you can look at to see (and open/close) the garage door position.
