Installing the Refoss monitor felt like giving my home an energy X-ray vision. Those orange clamps stood out like traffic cones in my electrical panel, making installation surprisingly intuitive despite the warnings.

The real magic happens in the app - watching my dryer's power draw drop and getting a Home Assistant alert when laundry's done? Priceless. Though setting up that automation required some tech-savvy tinkering.

Accuracy is impressive - my Fluke meter confirmed readings within 2% variance. The solar tracking feature became our family's new obsession, turning energy conservation into a daily competition.

Two quirks worth noting: The manual reads like it was translated through three languages first (that circuit multiplier confusion cost me an hour), and those backward-reading sensors had me reopening my panel before discovering the firmware fix.

For tech-forward homeowners willing to navigate some initial setup hurdles, this transforms how you interact with your home's energy flow. Just keep your electrician on speed dial for installation day.
