Home Air Conditional controller via esp32

• Opps I lost my ac remote :D it's ok let's create one with esp32

How it works

• A lot of household things (TV, AC, Speaker) is controlled by IR signal -> we can use esp32 with an IR transmitter module to control them

I use

• esp32 dev kit v1 (30 pins)
• KY-005 IR transmitter module which can emit ir light in range of 10m

Code

• thanks to this repo: https://github.com/morcibacsi/esp32_rmt_midea_ir_tx things getting easier
• Setting ir transmitter and esp32_rmt_midea_ir_tx lib

#include <midea_ir.h>

const uint8_t MIDEA_RMT_CHANNEL = 1;
const uint8_t MIDEA_TX_PIN = 4;

void setup()
{
  Serial.begin(9600);
  // init library
  midea_ir_init(&ir, MIDEA_RMT_CHANNEL, MIDEA_TX_PIN);
}

• for example to turn on AC with 23 degree celcilius with mode cool and fan level is 3

    ir.enabled = true;
    ir.mode = MODE_COOL;
    ir.fan_level = 3;
    ir.temperature = 23;
    midea_ir_send(&ir);

• easy right ?

toodo

• Complete logic code by implement functions to control the AC
• Remote interfaces: bluetooth, web app, telegram bot
• Some extra feature like: auto turn off when outside temperature is cool (so my roomate dont abuse my ac which increase my electricity's budget)
• Auto balance the ac temperature and outside temperature via and DHT22 sensor
• More base on my imaginations....
