Yes, Less, you are right(you so often are

).
I did go and buy a computer, I did connect to the Internet, but I made sure that I had some kind of protection from some of the evils out there...and YES, I do know that all the protection in the world is not foolproof, but I make the best fist of trying to ensure my security.
I neither need nor want one of these intrusive meters(and I have nothing to hide).My energy readings are done each quarter...I have not had an estimated bill in 14 years - the time I have been retired. I do not need some animated display to remind me of the energy I am using. I am frugal in my use of energy. No dishwasher, no dryer. I do not leave things on standby. We heat the house with a log burner. I am not who the energy companies want for a customer.
I am suspicious of such things for the reasons I have outlined quite clearly, but if it works for you, then you go for it. Me not having one leaves one for someone who will find one of these gadgets a boon.
I am suspicious about the information collected...how it will be used and by whom. Is is going to be passed on to third parties who could benefit from knowing what you use and when.
As for these leading to cheaper power...I can't see it happening. These contraptions have cost us the consumers 11 million quid. It won't reduce the carbon footprint because most people will selfishly use whatever power they want, and can afford to pay for.
Also there is the possibility of the energy companies being able to control the meter remotely
As for the housework...most of mine gets done during the week...and at the weekend I frequently invoke the 'sluts' charter. I do nowt....or no, I do just the cooking.
