      <p style=”text-align: left;”>Hey everyone,
      I recently bought two emporia energy meters gen2.
      One I called main and the other I called sub. Sub is meted under Main. The 3 200A CTs (have three phases, am from Germany) I installed on the main device. Sub doesn’t have any 200A CTs installed.
      The three 200A CTs are measuring the overall Power. From there it split of in two circuites with 32 breakers overall (12+20). The first 12 breakers are measured with the „main“ device. The rest 20 breakers from the other circuit, are measured with the sub device (16 of them) and the 4 left from the main device.
      I now get Balance Values varying from 0 to over 100% most of the time it’s around 30%. If I now sum very of the 32 measured values up, it does not match the sum shown in total usages. Also if I substract the total usage, from the summed 32 values, it does not result in the shown balance. By the way, Balance is shown in green.
      So what is wrong here???</p>

      So, after checking again, the Balance always seems to be the amount (approximately) shown, what the „sub“ divice is measuring. But why is that? The three 200A CTs are clamped on the main Wires. They should measure both circuits????
