Need Help With My Project

Yeah I tried it;and it seems to work fine :slight_smile:

It wasnt in my code but it was in the newer version of the blynk edgent example

Oh look, you were using a very early version of the Edgent example!

I also want to add a door sensor to pin 14 and display the if the door is open or not on a widget lcd
is this correct

#define BLYNK_TEMPLATE_ID ""
#define BLYNK_TEMPLATE_NAME ""

#define APP_DEBUG
const int wifists=2;
const int doorpin = 14;
int slider;
#include "BlynkEdgent.h"
BlynkTimer timer;
#define USE_NODE_MCU_BOARD
WidgetLCD lcd(V3);

BLYNK_WRITE(V7)
{
 slider = param.asInt();
}

BLYNK_WRITE(V0)
{
  int pin = param.asInt();
  if (param.asInt()){
  digitalWrite(16, LOW);
  timer.setTimeout(slider, [] () {digitalWrite(16, HIGH);Blynk.virtualWrite(V0,LOW);} );
  } else {
  digitalWrite(16, HIGH);  
  }
}

  BLYNK_WRITE(V1)
{
  int pin = param.asInt();
  if (param.asInt()){

  timer.setInterval(100L, doorstate);
}

  } else {

    lcd.print(0, 0, "Door Closed");

  }
}

    Blynk.syncVirtual(V7);
}

void loop() {

  timer.run();
