This has lead me to wonder about smart meters. I would quite like one if

it would provide the data for me to end up with an MS excel graph

showing how much power I use in each hour of the day. Is this likely to

be possible? I don't want to read the meter every hour, I could do that

now.



From what I have learnt so far, not all meters are the same, and if you

have one and then change supplier, the new supplier may say that the

meter is incompatible with their systems.



I should say that as a way of life supplying meter readings once a year

and then sorting out the bill is quite good enough for me.

It's not hacking that worries me so much as remote-disconnect it the hands of the power company. A little glitch from your bank, or one of those 2-million-quid bills, and they'll be power-mad keen to disconnect you at the press of a button.

(the hackers won't wait for a full roll-out, there'll be a new exploit every few weeks, until the meter supplier wises up - and finally discovers security)

In fact the hackers will create plausible doubt - that bill can't be right.
