[Lowfer] AC utility meter data signal

[Scott Tilley]

Hi Dex

Can you look at the meter and send me any information that would 
identify who made it ?  A picture would be nice :-)

Does your utility offer any online information about their smart meter 
program?

Thanks,
Scott

I am going to see if I can shunt some of it by decoupling using some 660VAC 13uF's - may get some complaints!
