Making a Raspberry Pi Garage Door Opener

A few years back I built a neat project I found online. It was originally designed by Andrew Shillday. You can find the code here. I decided that a Raspberry Pi Zero was sufficient, so I had to modify the pins used, but otherwise it was a fairly easy project.

The way it works is pretty simple. The Raspberry Pi Zero runs a simple server with an API endpoint. The mobile app connects to the API, authenticates and makes API calls to the configured endpoints. Since I have 2 garage doors, I configured the server for both independently. After I assembled the unit and wired it, I decided to expand upon it by creating a Grafana visualization to view two timelines - one for each door.

I used a small USB wifi dongle for connectivity as I don’t have a Pi Zero “W” model.

Here are the pictures:
