Building ones own HomeKit Thermostat with an ESP32 #ESP32 #HomeKit #IoT #InternetOfThings #Arduino

The Stay Caffeinated Blog posts a build of a HomeKit compatible thermostat build:

I’m pretty obsessed with controlling most of the electronics in my house from my phone. One of the last remaining devices was the thermostat. I don’t want a Nest because it doesn’t work with HomeKit, and I can’t use an EcoBee because I don’t have a neutral wire. So I resolved to build my own.

It was very important to me that the thermostat worked on homekit, thankfully there are already great homekit (hap) resources for the esp32. After some digging I decided on this homekit package, as it’s a clean port of the expressif homekit library to arduino. There are about 15 different homekit frameworks for arduino, so at some point I just had to choose one and start running.
