The code below should work for you.

It's the number of books you should read on the subject before asking
a question.

Apart from just asking for code, which most of the time doesn't work. Your
request also lacks the information about what kind of meter.
You should first know that there are a lot of different meters and quite a number of used protocols. Find out which one you need to use.
Then gather information about this protocol, this can be difficult because most of these protocols are either proprietary or behind an NDA.
Having said that, most digital meters have a LED that blinks when x amount of energy is used. And that is simple, count the time between blinks and use the value that is listed on the meter (kWh/blink) to calculate what you need to know.

Good for you, now start reading the documentation.
I looked up the documentation from the manufacturers
website and found out that Kevin gave you more then
enough information to get started.

Maybe you could get Siemens or ABB to send you their code.
