I need Help my project - temperature control

Need Help With My Project
1

I wrote this code
It controls the temperature of my aquarium.
I have a problem
when I turn on the hardware and I do not have internet the code hangs
is waiting for the intern
is it possible to run the temperature control routine without the internet?

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <OneWire.h>
#include<DallasTemperature.h>
#define ONE_WIRE_BUS 2 // DS18B20 on arduino pin2 corresponds to D4 on physical board

OneWire oneWire(ONE_WIRE_BUS);
DallasTemperature DS18B20(&oneWire);

int Ventilador = 5; // FAN
int Aquecedor = 4; // heater

/* TIMER */
#include <SimpleTimer.h>
SimpleTimer timer;

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

float temp;

// Your WiFi credentials.
// Set password to “” for open networks.
char ssid[] = “rede”;
char pass[] = “passs”;

WidgetLED led1(V1);
WidgetLED led2(V2);

void setup()
{
// Debug console
Serial.begin(9600);
DS18B20.begin();

timer.setInterval(1000L, getSendData);
pinMode(Aquecedor, OUTPUT);
pinMode(Ventilador, OUTPUT);

Blynk.begin(auth, ssid, pass);

}

void loop()
{

timer.run();
Blynk.run();

if ( temp > 27.00 ) {
digitalWrite(Ventilador,HIGH);
led2.on();
}
if ( temp < 26.50 ){
digitalWrite(Ventilador,LOW);
led2.off();

}

if ( temp < 24.50 ) {
digitalWrite(Aquecedor,HIGH);
led1.on();
}
if ( temp > 25.00 ) {
digitalWrite(Aquecedor,LOW);
led1.off();

}

}
/***************************************************

  • Send Sensor data to Blynk
    **************************************************/
    void getSendData()
    {
    DS18B20.requestTemperatures();
    temp = DS18B20.getTempCByIndex(0);
    Serial.println(temp);
    Blynk.virtualWrite(10, temp); //virtual pin V10
    }

yes , but loop must contain only timer.run and blynk.run

void loop()
{
timer.run();

// none blocking function

  if (Blynk.connected()) {  // If connected run as normal
    Blynk.run();

  } else if (ReCnctFlag == 0) {  // If NOT connected and not already trying to reconnect, set timer to try to reconnect in 30 seconds
      ReCnctFlag = 1;  // Set reconnection Flag
      timer.setTimeout(30000L, []() {  // Lambda Reconnect Timer Function
      ReCnctFlag = 0;  // Reset reconnection Flag
      ReCnctCount++;  // Increment reconnection Counter
      Blynk.connect();  // Try to reconnect to the server
    });  // END Timer Function
  }
}

and setup must contain

timer.setInterval(60000L, tempUpdate); //60 seconds for temp update
.
.
.

void tempUpdate(){

if ( temp > 27.00 ) {
digitalWrite(Ventilador,HIGH);
led2.on();
}

if ( temp < 26.50 ){
digitalWrite(Ventilador,LOW);
led2.off();
}

if ( temp < 24.50 ) {
digitalWrite(Aquecedor,HIGH);
led1.on();
}

if ( temp > 25.00 ) {
digitalWrite(Aquecedor,LOW);
led1.off();
}

}
