Had a smart meter installed last year, noticed I am not using all the solar I produce first before drawing on the grid. I am pumping solar power into the grid at the same time as I'm drawing on it. Power usage has changed to reflect this. The meter is an E355 and I cannot find any information to tell what all the various tariff codes are on the display. Not particularly impressed with this whole deal. Smart meter for who? Certainly not the customer.
