I bought a House Energy Meter on sale awhile back (thanks for the heads up @TheKorn) and just now got around to installing it. After a bit of a problem that a restart of OH solved I’m getting values for all the channels.
My problem is I don’t know how to interpret the numbers.
I understand the kWh channels and expect it continues to count up until reset though the reset channel.
I interpret the watts channel to represent the current instantaneous watts consumption (over some small period of time, or is this the derivative of kWh for an instant in time?)
But what is Power? It is a value that is always really close to but a little off from the watts channel.
I’m a computer scientist, not an electrician or electronics engineer and it had been over a decade since I’ve looked at this sort of thing. Nothing I remember and nothing I’m finding through Google is helping me figure out that value.
