Virtual meter

Post by jeanmarc » Wed Dec 25, 2013 9:28 am


If you don't have a household's consumption meter but own a smart-meter, you must create a virtual household meter.
The house's instant power consumption is simply : Solar power value - Output power + Input power

Ain't complicated (yet) ;)

Now, you'll need to know the household's consumption in Wh. You can't do a simple total counters addition/soustraction as a counter may pass-over at any time.
The solution is: Take the differential of each meters during a period. Then, increment the “virtual household” counter.
The "p1household" is an communication example of this.
