Like DAB radio
The smart meter technology is already out of date. But like DAB radio the government is unable to contemplate that the technology is outdated/unwanted/unneeded and offers nothing to the consumer they can not get elsewhere better and cheaper. A small monitoring device which communicates with a smart meter app is all that is required to give the "benefits" to the consumer, they don't need a LCD display, and they don't need the ability for the power companies to remotely turn off their power.
I've had the same conversation as a poster above but refused one one the grounds that it did not encrypt what I considered personal data (the times I am at home or not - as I live alone this would be easy to determine) and as such contravened the data protection act. Via DD they already have control of how much I pay them the least they can do is ensure I have power when I want it.
