I have a similar question and problem. I have a 42 position main panel. I have all the sensors installed, but obviously several circuits are not individually monitored. I have all the big items monitored (heatpump, well pump, kitchen, washer, dryer), but I still regularly get a balance of 20-60% at the end of the day. I have been moving some of the extra non critical sensors around to find where the extra draw is coming from, but only find those circuits pulling less than a percent. My plan is to turn off all breakers that don’t have their own sensor and see if the balance goes to zero, but I have to wait for a time when my family will not be bothered by Dad’s project.
My main question is that I do have some sensors monitoring multiple circuits. For example, my heatpump and air handler have independent 240v circuits, but I ran a leg from each through one sensor with a scale factor of 2. I made sure to use the same leg from each dual pole breaker. My multimeter was dead last night so I couldn’t check, but does it sound like I’m doing something wrong?
thanks,
Tom
