    Look up “home energy monitor”. They install inside your panel. The one we have has a bunch of current clamps, but not enough for our huge panel, so I chose what I thought our more heavily used circuits were. It also measures line voltage. Voltage x current = bingo. I’m not completely sure how I feel about the one I bought, so I’m not going to call it out. I wish it flagged trends per circuit over time to catch things like failing appliances. I could root it and mod it, but it would be nice if it did it out of the box. Catching a failing appliance would more than pay for the device, even if you do it by hand by simply tracking the data. It has slightly changed our habits (see: the furnace blower that we left on all the time and was pulling a constant 500 watts aka 12 kwh/day aka 360 kwh/mo), but I wouldn’t expect to find anything crazy unless you have high usage.

      Thanks! Looks like lots of options out there.

      Our power panel is old and we’ve been advised it may need replacing. I briefly looked at Span panels, with built-in energy monitoring, but they’re not cheap. These monitors look like you at least get the data at a much more reasonable price.
