I’m probably being really blind, but although I can see plenty of articles converting a power reading to an energy usage reading… I can’t see anything that gives the reverse conversion.
I have a pair of optical pulse inputs, both pulse per kWh.
That’s fine, and I trust and can read the graph generated - but I would like to get a graph of the power usage, even if averaged over 5 minutes.
When I try to create a visualisation with a histogram the values don’t seem to match what I expect - in particular the “power” values of the histogram vary wildly as I change the bin period, which isn’t what I expect a histogram to do at all.
|'m clearly doing something wrong, I just can’t see what at the moment.
