Sorry, I understand that reversing the CT wiring will invert the measurement.
However, my Energy Monitor 1, 2, and 3 are wired identically, with all the CT clamps installed in exactly the same direction. So why does EM1 report the correct polarity while EM2 and EM3 report the opposite polarity?
Could we have a parameter in the new firmware to configure the direction independently for each channel, for example by multiplying the measured value by -1 when required?
This would also make it possible to compensate for any polarity differences between the three Energy Monitor modules.
