Got Iotawatt setup. Split phase system - added mains and monitoring most but not all circuits. After configuring an output to calculate the remaining power usage of my unmonitored circuits, I’m getting negative reading on remaining circuits. Not sure what I’ve done wrong. I checked the mains CTs to make sure no paper is left between connections. Only thing I saw was one CT has some discoloration on one of the contacts. Not sure if that’s related or not.
