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?

    if the draw is so low, does it matter?

      Yes. Low power draws add up. 5W here 10W there and you’re already looking at >3€ per month.

          The problem is that it’s not just 15W; I merely used that as an example of how even just two “low power” devices can cause an effect that you can measure in euros rather than cents.

      You kind of have a point, but only to an extent. If the error in your measure is around 20%, are you really measuring anything?
