NODE MCU V3+ BLYNK + DS18B20 перестает читать показания датчика

Если не использовать BLYNK  то все работает, помогите разобраться в чем проблема.
Питание ни с пина 3,3 ни с Vin не решает проблемі

  Serial.begin(115200);
  delay(100);
  BlynkEdgent.begin();
  sensors.begin();
}
void  getTemp () {
    sensors.requestTemperatures(); // Send the command to get temperatures
    float tempC = sensors.getTempCByIndex(0);
     if(tempC != DEVICE_DISCONNECTED_C) 
  {
    Serial.print("Temperature for the device 1 (index 0) is: ");
    Serial.println(tempC);
  } 
  else
  {
    Serial.println("Error: Could not read temperature data");
  }
    delay(1000);
  }
void loop() {
  BlynkEdgent.run();
  getTemp ();
}
