Smart Meter

I'm not sure that's particularly relevant to the OP's request for info about domestic smart meters, is it? 🤷‍♂️

Not confused, I know what I’ve got. Simply opening up the options for the OP in case a half-way house might suit better.

Not at all.  Those of us contributing to CT are a small sub-set of caravanners, and caravanners are a minority with regards to the general population, so our experiences and opinions cannot really be seen as representative.  

Where we live unless there is a big problem in quite  a few households?

When as one seems to as we get older ,need the toilet in the early hours,

The amount of houses that are lit up with inside and outside lights is quite amazing,

The house opposite especially has cctv cameras (three) all are backed up by lights? suits us, as the cameras also cover the area of our boundary,I cannot think how high some electricity bill are

I'm not sure how your 'habits' are in any way relevant but thank you anyway. 

I cannot think how high some electricity bill are

Actually for me I cannot think what anyone's electricity bill, high or low, is and really I never try. Up to them. 

You make a reasonable point….the core of this issue and raison d’etre for smart meters is about understanding and managing power consumption. Owners of LVs probably pay more attention to such issues, particularly those who venture off-grid. It’s a good discipline to adopt whatever your method.

I would say neither for everyone. For me it's simply to get my readings to the energy provider as easily as possible. For the provider it's about not employing someone to do it or relying on someone doing it.

And others have posted about not using the associated display monitor?

Personally I'm not at all interested in understanding or managing my usage.

But many are ,and not all can afford to ignore that 

Although by the power usage by some in our area they seem not to understand

Personally I'm not at all interested in understanding or managing my usage.

I just find the information the display provides interesting. We are fortunate in that we don’t have to count the penny’s. I would think for anyone who has to closely manage expenditure,  they would be very useful. One thing that is interesting is how much is still consumed by the freezer, router, sky box and a couple of security cameras, when we are away for 6 weeks.
