[Jeff Sandberg] has put a good bit of effort into including photo voltaic and battery storage with related smarts to his house, however his power utilization statistics had been incomplete. His answer was to read data from the utility meter using RTL-SDR to fill within the blanks. The outcomes are good thus far, and there’s no motive comparable readings for fuel and water can’t even be completed.
[Jeff] makes use of the open supply house automation software program Home Assistant which integrates properly along with his photo voltaic and battery backup system, however because of the manner his home is wired, it’s solely conscious of about half of the power utilization in the home. For instance, [Jeff]’s heavy home equipment get their energy immediately from the facility firm and aren’t a part of the photo voltaic and battery methods. Which means that House Assistant’s power statistics are incomplete.
Happily, within the USA most good meters broadcast their knowledge in a fashion that a cost-effective software-defined radio like RTL-SDR can entry. That supplied [Jeff] with the information he wanted to get a way more full image of his power utilization.
Whereas getting knowledge from utility meters is conceptually simple, truly implementing issues in a manner that built-in along with his system took a bit extra work. If you happen to’re discovering your self in the identical boat, you’ll want to have a look at [Jeff]’s documentation to get some concepts.
