How to Calculate kWh from kW

[JoelHaggar]

Here is a post in our wiki for a Meta Data Script to calculate kWh from a kW reading. It's not going to be as accurate as an actual kWh meter but sometimes all you have is kW.

var lastKw = p1.lastValue(1);
var nowKw = p1.lastValue(0);

var period = nowKw.time - lastKw.time;
var kWlast = lastKw.value;

return kWlast /  (3600000/period);
