Midea Direct

ESPHome component re-written for ESP IDF, converted from dudanov MideaUART to be used with ESP32 C6 MINI (WT0132C6-S5).

Control is possible with a custom dongle. You can make it yourself according to my repo: HERE.

A far from complete list of supported brands:

1. Midea
2. Electrolux
3. Qlima
4. Artel
5. Carrier
6. Comfee
7. Inventor
8. Dimstal/Simando
9. Beko

Using

It's simple. Just use esphome and create your yaml as this below:

substitutions:
  name: "clima-test"
  friendly_name: "Clima Test"
  idname: clima_test
  #with this and the below code, you can disallow changing temperatures above or below threshold using IR or HASSIO/MQTT
  min_temp: 18
  max_temp: 26

#Include the board used

  name: $name
  friendly_name: $friendly_name

#possibility to use zigbee with ESP32 C6, in this case only ZigBee Router, but you can configure climate appliances
