Also, if you want to support your local organic cannabis farm, I
understand they compare smart meter readings with the street
sub-station to see if anyone has accidentally bypassed their meter.

Don't be silly. Sub stations are not metered.

But where did I say that that they were?

In your quote above. If the substation has no meter then what are you
comparing the sum of the smart meters usage with?

The concept is that the supply co. has some way of knowing how much juice
is being supplied from the station. If all of the houses supplied have
smart meters and there's a difference then there's a problem and/or someone
has bypassed their meter. Oh, 'accidentally' should have had a smiley after
it, sorry.

The substation also powers hundreds of legally unmetered supplies such as
street lights and traffic crossings.
