Calibration of SCT013 current sensor about esp32energymonitor HOT 2 OPEN

I've troubles adapting this code to work on Kincony M16v2 where I've fully calibrated SCT013 sensor but only apparent power calculations. On the below screenshot the voltage reading is accurate (~0.2V error). I've calibrated CI1 but I don't know if this approach will work for for varying current (like standby using 5W and PF 90 and turned on 35W PF 45).

Nonetheless power factor doesn't seem to be right. @danpeig Can you please advise?

For this particular device PF is 45 and load current is 33W.
