Hello, I recently set up Iotawatt and have been monitoring my usage for the past month.
I have a North American split-phase install, 100amp service, with a solar inverter feeding into the panel as well.
I’m tracking a few busy circuits - dryer, electric car charger, dish washer, fridges. What i’ve noticed is that even when we’re out of town (and all lights/computers are off) we’re drawing a pretty consistent 200 watts. Seems high. I just tried shutting off all the circuits at the panel except for those i’m monitoring to find whatever is vampire-draining, and i still can’t account for the 200 watts. So, figured it was the mains CTs acting up. I put all 3 of the 100 amp CTs i have on a single main and they’re all within 30 amps of each other (not great - one is quite different, but not 200 watts different).
Any suggestions? See pics below (i’m home with some lights on, and my computer, hence “other” is reading 318 watts instead of 200. but it basically never drops much below 200).
