Is there any way to include a count up timer. Ideally formatted as days/hours/mins/secs.
The background is that I use a sonoff pow with tasmota firmware. Using the total power reading to give the power used over a period of time. I can reset the power recorded but have no way to know how long it has been logging for. I would like to add a timer that can be reset when the logger is reset and show in the front end.
