Niestety soft od pow r2 nie dokonca dziala nie dziala licznik energii, nie dziala niebieska dioda reszta jest ok, na pow v2 dziala wszystko po za licznikiem

czy moglbys dodac obsluge ukladu cse7759 ?
CSE7759 and HLW8012
There is a significant difference in the data sheets between CSE7759 and HLW8012 The most important difference is a note that is in the CSE7759 datasheet and not in the HLW8012 this may be the reason for measuring energy when no load is connected See Page 10.
Note: Due to the noise of CSE7759, if there is no signal input, there will be about 2Hz signal output on the CF1 pin indicating the current and voltage rms value (this signal can be judged by the CF pulse frequency to hide the movement). To ensure the correct measurement of the effective value, the effective value of the current applied to the channel V1P\V1N shall not be less than 40uv, and the effective value of the voltage applied to the channel V2P shall not be less than 480uv. When using, please consult our technical support.
A other difference between both is also found in the Limit rating page 8 (CSE7759) page 6 (HLW8012) of both datasheets. It is the Max voltage between V1P, V1N, V2P for HLW8012 it is -2/+2 volt for CSE7759 it is -1/+1 volt.
Last difference is found on page 9 (CSE7759) page 7 (HLW8012). It is the application diagram. CSE7759 has on pin 4 (VP2) 2 resistors and 1 capacitors. The two resistors are a voltage divider set to 1000/1 Where the HLW8012 has the same circuit build up out of 6 x 470K and 1K resistors making a voltage divider set to 2820/1.
I think it would be good to know from people who are reporting strange energy measurements the exact type of chip installed in the SonOff Pow.
