you are welcome my friend

Thanks for the help and patience my friend …
Now I have to realize the part of the project related to the 433Mhz RF receiver that is mounted on Arduino NANO

Upon receipt of the data package, eg 1455 the relay 1 is energized and when the packet 1488 is received, relay 1 goes into the off state …

Help me?

Thanks so much.

Quiet simple !
this is a part of my code to receive the packet, you have to adapt it

void setup()
{
  Serial.begin(115200);
  mySwitch.enableReceive(0);  // Receiver on interrupt 0 => that is pin D3 nodemcu
  timer.setInterval(100, receiver);

void receiver() {
  if (mySwitch.available()) {

    int value = mySwitch.getReceivedValue();
    if (value == 0) {
      Serial.print("Unknown encoding");
    } else {
      Serial.print("Received ");
      Serial.print( mySwitch.getReceivedValue() );
      Serial.print(" / ");
      Serial.print( mySwitch.getReceivedBitlength() );
      Serial.print("bit ");
      Serial.print("Protocol: ");
      Serial.println( mySwitch.getReceivedProtocol() );
      Blynk.virtualWrite(V6, mySwitch.getReceivedValue());//received code to V6 value widget
    }
    mySwitch.resetAvailable();
  }
