I am facing same problem.I am using Nodemcu ESP8266 12e.
This my original code

#define BLYNK_PRINT Serial // Comment this out to disable prints and save 
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <SimpleTimer.h>
#include <TimeLib.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "xxxxxxxxxxxxxxxxxxx";

// Set your LED and physical button pins here
const int ledPin = 16;
const int btnPin = 5;

SimpleTimer timer;
void checkPhysicalButton();

int ledState = LOW;
int btnState = HIGH;
void sendUptime() {
  Blynk.virtualWrite(V20, millis() / 60000);
  long rssi = WiFi.RSSI();
  Blynk.virtualWrite(V15, rssi);
}
void setup()
{
Serial.begin(115200);
  pinMode(ledPin, OUTPUT);
  pinMode(btnPin, INPUT_PULLUP);
  digitalWrite(ledPin, ledState);
  timer.setInterval(100L, checkPhysicalButton);
  Blynk.begin(auth, "xxxxxxx", "xxxxxxx");
while (Blynk.connect() == false) {
    // Wait until connected
  }

timer.setInterval(60000L, sendUptime);
  // Setup a function to be called every 100 ms
  
}

bool isFirstConnect = true;

// This function will run every time Blynk connection is established
BLYNK_CONNECTED() {
  if (isFirstConnect) {  
    Blynk.syncAll();
    isFirstConnect = false;
  }
}


// When App button is pushed - switch the state
BLYNK_WRITE(V2) {
  ledState = param.asInt();
  digitalWrite(ledPin, ledState);
}

void checkPhysicalButton()
{
  if (digitalRead(btnPin) == LOW) {
    // btnState is used to avoid sequential toggles
    if (btnState != LOW) {

      // Toggle LED state
      ledState = !ledState;
      digitalWrite(ledPin, ledState);

      // Update Button Widget
      Blynk.virtualWrite(V2, ledState);
    }
    btnState = LOW;
  } else {
    btnState = HIGH;
  }
}

void loop()
{ timer.run();
  Blynk.run(); // Run Blynk
  // Run SimpleTimer
}

I have tried your code but got many errors. can explain how to implement this your my code???
