HomeKit Air Conditioner

HomeKit air conditioner remote control built with ESP32 (NodeMCU-32S) and HomeSpan

The IR signal of the Teco A/C is also decoded and analyzed in this project. (My A/C is not supported by the IRremoteESP8266 library 🥲)

Components

The Homekit accessory contains multiple services:

• Thermostat: the main service of the remote control
• Fan: utilize the rotation speed to set up different modes. Both swing and fan mode are the Fan service

Usage

• Set up the Wi-Fi credentials and pair the device by Homespan tutorial
• Modify the IR module based on your A/C model

Source code

• air-conditioner: the main project for the remote control
• passive-sensor: test project that built a HomeSpan accessory for DHT22 sensor
• irsend: test project for IR signal decoding and transmitting

Hardware Device

• NodeMCU-32S
• DHT22: Temperature, humidity sensor
• Keyes IR Transmitter: Sending the signal to A/C
• Keyes IR Receiver: Decoding the IR signal from your remote control
• Homepod mini: HomeKit accessories require Homepod/AppleTV as home hub

Libraries

• HomeSpan
• Adafruit DHT Sensor Library
• IRremoteESP8266
