So I wanted to get myself a Kill-a-watt. Being who I am, I wanted information regarding its accuracy, especially at low power draws. I found a comparison with a industry grade equipment (Fluke is about the best out there in handheld electrical meters). It’s not encouraging, so I thought about a more proper meter, but it’s not easy to find an actual power meter that is accurate at low loads, isn’t a hassle to install and doesn’t cost an arm and a leg.

What do you use? Am I overthinking it?

    Many residential tools can’t even be calibrated. Even if they are, calibration stability is a concern. The difference between a cheap instrument and a good one is short and long term repeatability.

    Thanks for pointing open energy monitor, that seems overkill for what I need.
