I got a successfully I2C-communication with my ADE7953.
Everything works fine, I'm able to read VRMS, IRMSA, IRMSB etc.
Also angle and period measurement works as expected.
All registers returning reasonable values.


On all input channels I got 250mV, so to read power values should be possible.
But all power registers (AWATT, AVAR, AVA, BWATT, BVAR, BVA) are returnig exactly zero!


I also reset the measurement flags by reading the RSTIRQSTATA register.;


Did I forgot to start the power measurement?


Please can you give me a little support.
