NJ – just how do you think any (non-smart) electricity meter will need replacing due to obsolescence?
As long as there is a supply from the sub-station connected to your meter, the meter will continue to allow that electricity to reach the socket outlets within your home.
Most, if not all currently being installed smart meters allow the supply to your home to be switched off remotely – why would anyone want such a feature within the mains supply to their home?
Just wait until someone hacks the control and holds the supply company to ransom, threatening to disconnect a large number of house-holds. I bet that the supply company will wash their hands of the problem – blaming the hackers for your loss of supply.
