SONOFF POW cant calibrate power settings Again :(

Same problem in Version 1.12.4

Do you mean the calibration values are not persisted?

I have KMC-70011 (w/ HLW8012), ESPURNA 1.12.5a
Also, unable to calibrate energy monitor settings - they are way off.
Calibration using 50W resistive incandescent light bulb, and calibration settings are not saving/taking effect.

update, example discrepancies, attempted to set:
expected current: 0.414
expected voltage: 120
expected power: 50

the readings from espurna don't really change, and are more than 2x reality:

{"current":"0.995","voltage":"123","power":"132","reactive":"0","apparent":"122","factor":"100","energy":"0.046","time":"2018-03-17 15:21:17","mac":"<<redacted>>","host":"ESPURNA_237195","ip":"192.168.1.18","id":658160}

@xoseperez : btw, for KMC 70011 HLW8012_VOLTAGE_R_UP is 2 * 1000000 (2 x 105 resistors)

Staged for release

Hi again, something similar is happening in 1.13.1. I just got the POW and it is the first time I use it so I'm not sure if there is any special procedure for the calibration rather than connect it to a bulb, switch it on and write down the values under sensors... but I loose the values I write right after pressing "Save"

it looks to me the chip at the back is a CSE7759 and not a CSE7766, could that be the problem?
I have tried with 1.12.6 pow and powr2, 1.13.0 POW and POWR2 and 1.13.1 POW and POWR2, none of them allows me to store the values....
