I’ve been playing with Utility Meter, as a way of keeping track of my electric when I’m not around to read the meter etc.
I’ve got it so that it correctly reports peak and off peak usage via my PZEM-004T sensor on the main power feed, however I have manually set the peak and off peak times, because my provider specifies them as :-
- For summer time / April-October / - Day time zone lasts from 07:00 to 23:00 - Night time zone lasts from 23:00 to 07:00.
- For winter time / November - March / - Day time zone lasts from 06:00 to 22:00 - Night time zone lasts from 22:00 to 06:00.
I can’t quite figure out doing the season switch thing, for peak and off peak.
Then once I’ve got that figured, is it possible to keep a cumulative total for both peak and off peak, so that, it should be a good approximation of what my utility meter says. i.e. not monthly/daily cycle etc.?
