How I use Raspberry Pis for HomeKit automation by Adam Argo

I saw a HN post titled How I use my Raspberry Pis to help me work on with my side projects, which to me didn’t really seem to demonstrate the power of the Pi platform, like the GPIO pins — it was all just software you can run on a Linux machine. I thought what I’m doing with my Raspberry Pis is a little more interesting and takes advantage of its unique features, and thought I’d write about that. I use Raspberry Pis to run a few pieces of software to bridge incompatible devices (and homemade devices, including a model railroad switch controller, described below) to my HomeKit home automation system. Some work well, some not as much, but the Pis are great for bridging that compatibility gap. For the stuff I made, I link to GitHub repos that have the code that runs them.

If you’re already familiar with HomeKit and Homebridge and just want to see the meatier projects, I’d recommend skipping to the model train switch or the fireplace sections.
