I've loved getting emails from my garage door notifier, but I wanted something that I could just look at and know the state of the garage door. Enter the Garage door state indicator! Since my server is written in nodejs, I went with a raspberry pi + oled combo. Then stuck it in a nice black 3d printed case.

Hey look the doors open!

And closed :).

project files, code and assembly notes are on my github: https://github.com/thinklearndo/garagedooropennotifier
