And the last thing, count the devices, this i dont get…

Please explain to me.

He was probably referring to this…

 Serial.print("C: ");
 Serial.print(tempC);    
 Blynk.virtualWrite(Vpin,(tempC));
 Vpin++;
 if(Vpin >= 8){   // cycle through pins V5 to V7
  Vpin = 5;
 }

Which is fansnazzy and all… but not needed for a measly three pins… (but for 72 pins, now that is different )

 Serial.print("C: ");
 Serial.print(tempC);    
 Blynk.virtualWrite(V5,(tempC));
 Blynk.virtualWrite(V6,(tempC));
 Blynk.virtualWrite(V7,(tempC));
