I may be wrong but I don't think you get to interrogate the meter directly.

I seem to remember that you are (for at least some suppliers) required to
go to their web site for the results.

Anyway, I have a local clamp on device courtesy of Eon many years ago.

Up to a point I was following the official documents as the
metering standards were discussed, but I eventually gave it up.

It was certainly originally specified that the consumer must be
able to have access to view and download the data locally.
