Anyone had a smart meter installed in their property?

Got a installation booked for September 12th. I know what it is but just wondered what extra information does it give you?
Like exact gas/electric usage for each day? What else?
And I've heard that when it's fitted you no longer need to send meter readings every month?

I didn't find the right solution from the Internet.
