MideaUART

Arduino framework library for controlling Midea home appliances using the UART protocol.

Control is possible with a custom dongle. You can make it yourself according to numerous instructions on the Internet, or you can buy a ready-made one in Tindie Shop, thereby supporting me and my work.

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

Using

It's simple.

1. Create appliance instance of dudanov::midea::ac::AirConditioner.
2. Set serial stream interface and communication mode to 9600 8N1.
3. Add setup() and loop() methods to the same-named global functions of the project.
4. Control device via void control(const Control &control) with optional parameters.
5. You may optionally add your callback function for receive state changes notifications.

#include <Arduino.h>
#include <Appliance/AirConditioner/AirConditioner.h>

using namespace dudanov::midea::ac;

AirConditioner ac;

// Example how can change work mode easily
static inline void switchMode(Mode mode) {
  Control control;
  control.mode = mode;
  ac.control(control);
}

// Example how can change mode and temp in same time
static inline void changeState(Mode mode, float targetTemp) {
  Control control;
  control.mode = mode;
  control.targetTemp = targetTemp;
  ac.control(control);
}

// Example how can change power state
static inline void setPowerState(bool state) {
  ac.setPowerState(state);
}

// Example how can change mode to AUTO and set target temp to 25C
static inline void changeAuto25() {
  Control control;
  control.mode = Mode::MODE_AUTO;
  control.targetTemp = 25.0f;
  ac.control(control);
}

// Here you may get new properties states
void onStateChange() {
  ac.getTargetTemp();
  ac.getIndoorTemp();
  ac.getMode();
  ac.getPreset();
  ac.getSwingMode();
  ac.getFanMode();
}

void setup() {
  Serial.begin(9600);     // set serial baudrate to 9600 8N1
  ac.setStream(&Serial);  // set stream serial interface
  ac.addOnStateCallback(onStateChange); // add callback
  ac.setup();
}

void loop() {
  ac.loop();
}
