I have noticed a number of times that when I add up the 8 circuit sensors I have installed the Watt’s being drawn is more then the Mains sensor. Since the install I have been back in the panel a couple of times moving things around a bit. So I checked to make sure the clamps are closed and fully plugged in.
Downloading and viewing my raw data I see this happening a number of times. I do see what appears to be fairly balanced inputs for the mains on both legs. Saying that my daily usage seems to low to add up to what my Hydro company says I use.
Here are a couple times slots that I see quickly where this is happening. They seem to happen when there is a larger load on my electrical dryer or hot tub.
