Homebridge / Raspberry Pi / Arduino A/C Controller

This is a project that I'm working on to let me control my A/C using Homebridge and Apple's HomeKit.

Thanks to Mattia Rossi for decoding the Toshiba A/C signals so that I didn't have to.

Device Setup

• I've got Homebridge running on a Raspberry Pi, that allows me to access devices on the network using Apple's HomeKit.
• I've got a basic web server running on the Pi that receives on/off and temperature setting commands from any device on the network - and sends them to the Arduino via a serial connection.
• I've got an Arduino firing the IR signals off to the A/C to control it.

Files

irBlaster.ino

This runs on the Arduino that sends the IR signals to the A/C unit.

irServer.py

This runs on the Raspberry Pi and receives commands (via web requests) to change the state of the A/C. This facilitates the serial communication between the Pi and the Arduino.

index.js

This is the Homebride plugin that allows homebridge to talk to send commands and retrieve status from the irServer.
