This is such a bad idea.
I already have a meter for my electricity supply. It is simple - like me. It works 24/7/52. It is very tamper evident and so fairly secure.
Please can someone explain why the government, which has no mandate for this, is spending large amounts of MY/our/your hard-earned taxes on subsidising something that, if necessary by the power companies, I should be paying for through my electricity bill?
I'm really angry. I suspect there is not one electable political party out there that has either the vision or the bollocks to tell the civil Servants and power suppliers to come up with their own adequately secure solution if they really want one and then offer it to customers but make it optional for them to take it on.
