How do I read the usage information my electrical meter sends to my power company?
I live in Texas, and there is a public information type site that is maintained by a group called Smart Meters Texas.

Smart Meter Texas

On this site you can sign up, register your electric meter, and then see the data from it in 15 minute intervals.  The data is delayed about two days, but it's very informative.

You may search for your area or ask your public utility company if they have something similar.
