ESP Haier

ESP Haier is a project to use a ESP8266 (I did not test with ESP32) to control Haier Air Conditioner with wifi module supoort with ESPHome and Home Assisant.

You only need configure esphaier.yml, put Haier.h in the same directory and flash.

Home Assisant will recognize as climate device.

For now, ESPHome climate component don't support fan speed or swing, so, ESP Haier neither. When esphome will have support, I will add it.

This project is based in the works of Instalator and his project Haier Wifi

I use a Wemos D1 Mini with a "hacked" USB cable. I cut the USB cable and connect directly to Wemos:

  • Red -> 5V
  • Black -> GND
  • Green -> RX
  • White -> TX
You can’t perform that action at this time.
