Relay activation by blynk bridge

Need Help With My Project
1

Hello everyone, I have made a bridge project to have a relay activated by a temperature control. I have two nodemcu A and B. The NODE A controls the DHT22 and the NODE B controls the relay.
This is sketch A:

This is sketch B:

the scketch of NODE A works well, reads the data from DHT22 and sends them with the bridge to NODE B. now I can not activate the relay because? where I’m wrong, the two Blynk screens are set up well.
help me!!!

Try the following…

In scketch NODE A make an amendment:

if(t > 30){
     bridge1.virtualWrite(V5, LOW);      // relay on
  }else{
     bridge1.virtualWrite(V5, HIGH);      // relay off
  }

switch the relay to D1.
In scketch NODE B make an amendment:

const int rel = 5;    // pin NODE D1 tenda salotto abbassa

void setup(){
Serial.begin(9600);
Blynk.begin(auth, ssid, pass);
pinMode(rel, OUTPUT);    // imposta pin in modalità uscita
delay(10);
digitalWrite(rel, HIGH);
}

// This code will update the virtual port 5
BLYNK_WRITE(V5) {
  int pinData = param.asInt();
   digitalWrite(rel, pinData);
}
