Hi,
I just received my M16-v2.1 board and will use it with 10A and 20A 0-1V clamps. New to the forum :-)
I'm on a 3x400V+N network and connected L1, L2, L3 and N to the terminals to measure the voltage.
But the voltages that are reported seem to be too low.
I also have a Zennio Kes Plus KNX device that also measures voltage and power consumption. (top 3 values in image below).
I also tried 2 different multimeters and get nearly the same readings as the Zennio (and I measured on the inputs of the M16)
But the M16 readings are 8-12 volts lower.

Is there a way to calibrate the voltages?
I'm using home assistant with ESPhome
If not: can I use the voltages from another home assistant entity (my Zennio) and use these?
After that I would like to start calibration of the CT-clamps: is it advised to do individual clamp calibration for each connection?
Regards,
Nick
