Hello my friends
Please help on Blynk 2.0
Simple code to turn on a default LED but I don’t know why it gives me the value ON in both cases when I press the control button

// Fill-in information from your Blynk Template here
#define BLYNK_TEMPLATE_ID "TMPLJqpRzTuD"
#define BLYNK_DEVICE_NAME "ULTRA 1"

#define BLYNK_FIRMWARE_VERSION        "0.1.0"

#define BLYNK_PRINT Serial
//#define BLYNK_DEBUG

#define APP_DEBUG

// Uncomment your board, or configure a custom board in Settings.h
//#define USE_SPARKFUN_BLYNK_BOARD
//#define USE_NODE_MCU_BOARD
//#define USE_WITTY_CLOUD_BOARD


#include "BlynkEdgent.h"

const int Relay1  = D1;
#define vPIN_LedRelay1        V1
WidgetLED LedRelay1(vPIN_LedRelay1);

BLYNK_WRITE(V2)
{
  if (param.asInt() == 0)
  {
    digitalWrite(Relay1, HIGH);
    LedRelay1.off();
    Serial.println("OFF");
     
  }
  else
  {
    digitalWrite(Relay1, LOW);
    LedRelay1.on();
    Serial.println("ON");
  }
}


void setup()
{
  Serial.begin(115200);
  delay(100);

  BlynkEdgent.begin();
  pinMode(Relay1, OUTPUT);
  digitalWrite(Relay1, HIGH);
}

void loop() {
  BlynkEdgent.run();
}

Thank you, my friend,@Blynk_Coeur for the response. I made a blynk write to run a virtual LED and also Riley on D1, but there is no real response. Look at the code. There is no problem

It only turns on the LED and does not stop it. I already used this method in blynk v1 and didn’t face any problem

Some information about how you’ve configured your datastream would be useful.

Thank you my friend, can you explain more?

You will have created a template in the web dashboard and defined datastream(s).
You need to share details of that datastream setup.

Pete.
