Re: Power Line Communication
"It was back in saarf-east London that my smart meter sent half-hourly updates over the air to Hell HQ."
And why exactly do they need half hourly readings for sending me a monthly bill?
If they want to offer variable tariffs they can read an aggregated figure for each of the tariff bands at the end of the month. A bit like my economy 7 meter provides a monthly figure for both night and day usage. They don't need to know that I was cooking my dinner between 7:00 pm and 7:30 pm on Tuesday.
