Active Power in ADE7758

[nopodige]

Hi all,
I am using ADE7758 to get Active power. I am currently reading the AWATTHR register , i see that energy is getting accumulated in this register.

I need to calculate the active power . I read the datasheet and i didnt understand and got confused.

Please guide me..

I'M not using the device, but as far as I know the datasheet, instantaneous active (and reactive) power aren't accessible in registers. So calculating it from xWATTHR differences seems to be the suggested method. I guess, there are also application notes and software examples for the ADI energy measurement chips, did you search for it?
