KC868-M16 configure yaml for ESPhome

[nuovapentecoste]

What is the best setting for this clip?
I did various tests with zero load and with known load and I found these parameters to be very close to reality

      - calibrate_linear:
          # Measured value of 0 maps to 0A
          - 0.004 -> 0
          # Known load: 4.0A
          # Value shown in logs: 0.1333A
          - 0.61 -> 100

But it is not precise and is very variable.

Am I doing something wrong? Can I improve the accuracy?
