Just to pitch in, this is how I’m doing it:

void totalRuntime()
{
  if (digitalRead(blowerPin) == LOW) // If fan is running...
  {
    ++currentCycleSec;               // accumulate the running time, however...
    currentCycleMin = (currentCycleSec / 60);
  }
  else if (digitalRead(blowerPin) == HIGH && currentCycleSec > 0) // if fan is off but recorded some runtime...
  {
    Blynk.virtualWrite(110, ++hvacTodaysStartCount);              // Stores how many times the unit has started today... adds one start.

    currentCycleSec = 0;                                          // Reset the current cycle clock
    currentCycleMin = 0;
  }
}

totalRuntime is something that I have running every second. As you can see, this solution is intertwined with recording a current fan cycle runtime… something you may or may not be interested in! I reset all these values at midnight.
