HomeKit Thermostat - Daikin IR Controller - ARC452A4

This project has been created to intergrate my Daikin AC unit with Apple Homekit. This allows me to control the temperature of my home using my iPhone and Siri.

• Usage
• REST API
• Setting up Temperature and Humidity Sensor
• Learning Custom Remotes
• Running in Docker

Compatibility

This will probably only work on systems that support the Daikin Remote ARC452A4 remote control, but it may be possible to learn other remotes.

Your system must have lirc installed and an infrared emitter configured. This Guide shows the how to use a RaspberryPi and Lirc.

Setup

Build a lircd.conf file and copy this to /etc/lirc/lircd.conf:

./bin/init

Restart Lirc:

sudo /etc/init.d/lirc restart

Test this is working:

irsend SEND_ONCE daikin-arc452a4 off

Usage

Run the server:

node bin/www

You can now add the thermostat accessory in HomeKit. See https://support.apple.com/en-la/HT204893

The accessory pin code will be displayed in the console.
