it sends your useage directly to the utility company so no meter reading needed. You also have a hand held unit that tells you how much fuel you are using at any given time (and how much you havespent that day so far
There's a gadget called a "Watchman" that you can have fitted to your oil tank. It wirelessly tells your oil company when you need re-filling.
Saves all that poking with a stick to see how much is in there.
I can't see that it's a lot different from that really.
The nonsense comes mostly from their advertising, when they tell you it can save you money.
You can only save by switching things off. ;o)))
We’ve had our smart meter for about four or five years, not had a single problem.
We view our usage on an app we have on our iPads and iPhones, we don’t have a ‘device’ as such...well, we do but I don’t even know where it is :)
