How did it enable you to save 10%?

They don't, but knowing what you are using when, can empower you to
work out ways to save.
Every electricity consuming device I have has a number on it followed by
the letters KW. That tells me how much power it consumes as long as I
leave it on.

No it doesn't, it tells you the *maximum* power it will consume. Most
equipment takes only a fraction of the power indicated on the plate
most of the time.

A smart meter won't tell you the average consumption of a device which
is on a thermostat.
