dcbwhaley:Can the smart meter distinguish between the tails being disconnected or the main switch on the CU being opened?
The smart meter detects the meter cover being removed to gain access to the tails terminals and sends an alert. It also detects the power to the meter going away (e.g. power cut or head fuse removed) and sends an alert. In the latter case if the DNO gets alerts from the whole street it assumes a power cut and comes out and fixes it. If just one house, it sends out someone to ask questions.
It won't know about the CU main switch being open.
