Hi,
I'm sorry but I don't know how to perform a calibration when I have these values. What values am I supposed to use?
I tried with different attenuation settings for the ADC but always end up with jumpy values:
- no load connected: 'ai1': Sending state 1.03200 V with 3 decimals of accuracy
- 100W light bulb: 1.0360V
- 500W light bulb: 1.0310V
So I don't really see sensible values. Power factor of test devices is 100.
Jumper setting is set to V instead of A. Even tried switching them but don't see differences in the values.
From code example I see:
- calibrate_linear:
# Measured value of 0 maps to 0A
- 0 -> 0
# Known load: 4.0A
# Value shown in logs: 0.1333A
- 0.31749 -> 8.95608
=> but I don't have input values for the mapping. They are all random and in the same range regardless if there is load connected or how heavy it is.
Is something missing in the code/config?
