Hit problem with REMOTE CONTROL SOCKETS 433hz tutorial

Hi,
I've been following the REMOTE CONTROL SOCKETS tutorial, it was all going well.
Based on the photo in the tutorial I'm using the same remote and plug socket.
I was able to connect to pick up the remote controls "messages" (although I did use the transmitter with 4pins)

Having received codes (e.g. 0b1110010111111111000011100) I changed the setup to be a transmitter. (again using the transmitter with 4 pins only 3 pins connected)

This is where I get stuck.
I used the send code in the tutorial but none of my plugs turn on or off.
I double checked, and using the remote control it works fine.

I have recreated all of the wiring but still no luck.

Any tips on how I can go about debugging this or figuring out what is wrong?

I have the same receiver and transmitter as on this image:
After some tests I found that left one on the image is the transmitter (3 pins) and right one is the receiver (4 pins)

I using the code from example, here are my exact code with connections:

/**
  On press button BTN1 send bits (CODE variable) from transmitter (A1) to receiver (A0) multiple times. Blue LED blinking on send data, green LED blinking on receive data.
  
  Transmitter:
    GND <-> GND
    VCC <-> Bat
    ATAD <-> A1
    
  Receiver:
    GND <-> GND
    VCC <-> 3.3 (If using Bat there are many errors that we get on input)
    DATA1 OR DATA2 <-> A0
*/

var t,n, counter = 0;

// When the signal rises, check if it was after ~5ms of delay - if so (and if we have a code) display it.
function sigOn(e) {
 // console.log('sigOn:', getTime());
  var d = e.time-t;
  if (d>0.005 && n>0) {
    console.log(counter++, ":0b"+n.toString(2));
    n=0;
  }
  t = e.time;
  LED2.write(1);
}

// When the signal falls, measure the length of our pulse. 
// If it was within range, record a 1 or a 0 depending on the length. 
// If it wasn't in range, zero it
function sigOff(e) {
 // console.log('sigOff:', getTime());
  var d = e.time-t;
  t = e.time;
  if (d>0.0001 && d<0.001)
    n = (n<<1) | ((d>=0.0004)?1:0);
  else
    n=0;
  LED2.write(0);
}

setWatch(sigOn,A0,{repeat:true,edge:"ris­ing"});
setWatch(sigOff,A0,{repeat:true,edge:"fa­lling"});

var TX = A1;
var CODE = 0b10100000111111101110;

function sendCommand(command) {
  LED3. write(1);
  var bits = (CODE & ~0b11111) | command;
  for (var i=24;i>=0;i--) {
    if ((bits>>i)&1) {
      digitalPulse(TX,1,0.9);
      digitalPulse(TX,0,0.3);
    } else {
      digitalPulse(TX,1,0.3);
      digitalPulse(TX,0,0.9);
    }
  }
  digitalPulse(TX,1,0.001);
  LED3. write(0);
}

function sendMultiple(command) {
  var n = 9;
  var interval = setInterval(function() {
    sendCommand(command);
    if (n-- < 0) clearInterval(interval);
  }, 50);
}

var socketOn = false;
setWatch(function() {
  socketOn = !socketOn;
  sendMultiple(socketOn ? 0b11110 : 0b01110);
}, BTN1, { repeat:true, edge:"rising", debounce:10 });


// A1 -> transmitter (3 wires) green
// A0 -> receiver (4 wires) yellow

Hope this helps, LMK if you need some help, I passed it before few days. :)

BTW, how did you checked the remote control that it works fine?

PS: Here is additional good explanation for the code if you need it.

Thanks so much.
I had the transmitter and receiver the wrong way around.

Using your code I've now got a switch turning on and off! :)
Now I just need to figure out why only "channel 1" switches work and not 4.

Am I correct in thinking all I need to change is the CODE variable?

For channel 4 I get this output: 0b1110010111111111000011100
So I replace the current string in code with that but it still turns on channel 1.

Thanks again for your help.

@yayAdrian what do you mean "got a switch" and "channel"? Can you please add more details for what would be done? Thanks

Sorry,
Switch = wall plug
channel = the buttons on the remote say 1, 2, 3, 4

Still didn't tested the remote, it on it's way from Hong Kong , I sending and receiving the bits on the same board :)
But lets try to understand it.
Does each channel sends different code? just try to debug it with console.log()

So I went back to basics with the code and found that

sendMultiple(socketOn ? 0b11110 : 0b01110);

Was causing me the problem. I replaced that by passing the full code (e.g. 4 = 0b1110010111111111000011100) and I am able to turn all of the channels/1,2,3,4 on and off.
Thanks for your help. Hope you get your remotes and switches soon.

Glad you got it working eventually!

@yayAdrian: Did you change the line 'CODE=' in the code that you put into Espruino? If you didn't it may explain why you had to put the full code into sendMultiple
