- Wed Dec 14, 2016 4:28 pm #59504 Hi can someone help me I am trying to control my A/c through IR using the esp8266 I have been trying multiple things to make it work but unfortunatley to no avail. I managed to make my tv and other IR systems work but not the A/C. All other devices use a NEC protocol and the air conditioner is showing it has a Panasonic Protocol.

This said when I used the sendPanasonic specifying the Panasonic Address and the Hex for the IR it did not work either. So I resorted to use raw data (sendRaw) From the Ir Rec.

The data read dump I got when I switched off the A/C (Off Command) was the following:

Code: Select allEncoding  : PANASONIC
Code      : C4D3:64800004 (48 bits)
Timing[99]:

unsigned int  addr = 0xC4D3;
unsigned int  data = 0x64800004;

I am using this code:

Code: Select all#include <IRremoteESP8266.h>

IRsend irsend(0); //an IR led is connected to GPIO pin 0
unsigned int  rawData[99] = {3850,1450, 550,1300, 550,1300, 550,550, 550,550, 550,550, 550,1300, 550,550, 550,550, 550,1300, 550,1300, 550,550, 550,1300, 550,550, 550,550, 550,1300, 550,1300, 550,550, 550,1300, 550,1300, 550,550, 550,550, 550,1300, 550,550, 550,550, 550,1300, 550,550, 550,550, 550,550, 550,550, 550,550, 550,550, 550,550, 550,550, 550,550, 550,550, 550,550, 550,550, 550,550, 550,550, 550,550, 600,500, 600,500, 600,500, 600,500, 550,550, 550,1300, 550,550, 550,550, 550};  // PANASONIC C4D3:64800004


void setup()
{
  irsend.begin();
  Serial.begin(9600);
}
t
void loop() {
  Serial.println("Raw");
  irsend.sendRaw(rawData, 99,38);
  delay(2000);
}

Can someone pinpoint me in the right direction, would be great if I can put a finger on how to make this work!

Thanks in advance
Chris
