Hey folks, I found this post which appears quite similar: EmonPi - accuracy of new install - calibration required? - #7 by Zarch
TBH I am surprised a brand new emonpi can be so different to the meter values and I have to calibrate. I didn’t see such mentioned in the setup docs.
Instead of calibrating as described in the other post, I wonder if it’s OK to use the values from the smart meter? Is that recommended?
