Calibration issue M16v2 - RdP - 04-20-2024

Hi,

I've been strugeling with a calibration issue.

Code:
[13:25:21][D][ct_clamp:041]: 'Measured Current-16' - Raw AC Value: 0.010A after 216 different samples (432 SPS)

[13:25:21][D][sensor:094]: 'Measured Current-16': Sending state 0.13940 A with 5 decimals of accuracy

This is in the logging
But I specified this in the yaml config

Code:
  - platform: ct_clamp

    sensor: ai16

    id: Measured_Current_16

    name: "Measured Current-16"

    sample_duration: 500ms

    update_interval: 20s

    accuracy_decimals: 5     

    filters:

    - calibrate_linear:

      - 0.0 -> 0

      - 0.007 -> 0.004

      - 0.008 -> 0.004

      - 0.009 -> 0.004

      - 0.010 -> 0.004

      - 0.011 -> 0.004

      - 0.056480 -> 1.775

      - 0.114445 -> 3.61

      - 0.204695 -> 6.49

      - 0.286630 -> 9.01

      - 0.340460 -> 10.684

      - 0.535860 -> 16.89

A measured raw value of 0.010 should result in a 0.004 current value, but instead 0.13940 is the result.

What am I doing wrong here?

Thanks,
Rien

Hi I read that post already, but it's mainly about voltage calibration and I have an issue with current calibration.

Which part of the mentioned post are you reffering to?

Thanks,
Rien

what CT clamp type you are using? whether buy from KinCony? or yourself CT clamp sensor?
