Unless I'm reading it wrong that is last year's news - just making the first tranche of "smart meters" up to SMETS1??

Agreed Michaelw posts any old crap that he can find about smart meters without even reading it first.

If he did read it, he obviously does not understand what the document states!

Its the cost of installing legacy equipment to the customer,you have highlighted a problem.Cost!

A third of people (32%) who switched after getting a smart meter said their new supplier replaced their smart meter.

smart meter adverts are raising YOUR energy bills by £50million a year as power firms pass on cost of campaigns

A Youtube video showing a blank screen L&G g370 Smart gas meter from 2017,clearly these meters are not lasting the ten years life expectency.Worringly the below further states that in a loss of power situation it is capable of disabling the supply.This installation is the same as mine with a ground box instalation.

Both Smets 1/2 specify that

4.3.5
Monitoring
4.3.5.1Battery capacity Where a GSMS includes a Battery, it shall be capable of estimating the remaining Battery capacity in days (to facilitate replacement of the Battery before it is fully depleted) and storing the estimate in Remaining Battery Capacity(4.5.3.10).If the Remaining Battery Capacity(4.5.3.10) falls below ten percent of the nominal Battery capacity the GSMS shall be capable of:

i.generating an entry to that effect in the Event Log(4.5.3.5);

ii.sending an Alert to that effect viaits WANInterface;and

iii.displaying an Alert to that effect on its User Interface.

4.3.5.2
GSMS power supply
Prior to or at the loss of power, a GSMS shall be capable of:
iv.
Disabling the Supply, in circumstances wherethe Supply Depletion State

(4.5.2.14) is configured to require Disablement; and
v.sending an Alert to that effect on its WAN Interface.

With the L&G g370 can you see current battery level from the display?

There are some concerning points raised here to these device's and the possible implications of malicious activity.

How to Hack a Smart Meter and Kill the Grid

I’ve always been concerned about the vulnerability of the British smart meters to hacking at the manufacturing stage. The reason for that concern is that these meters contain an OFF switch which allows power to be disconnected by the energy supplier. This is a convenience for them, as they no longer need to send someone round to gain access to a building. However, if it were ever hacked, the hackers could turn off millions of meters at the same time. That could be used to destroy the electricity grid.

So far I’ve failed to get anyone involved in the UK program to understand this risk. The energy suppliers’ concept of hacking is limited to people bypassing or fooling individual meters to try and minimise their bills.

Smart meters are emphatically NOT free. We all pay for them. We pay for them even when they go from smart to dumb. We will then pay for them to be replaced or MAYBE actually updated to become smart again. The suppposed savings from installing smart meters has now reduced to less than 20% of what they originally said & as the original savings were very small, once we pay for the rubbish meters they install (which will only last at most a third of the time the old ones did) we definitely are not saving anythiing.

Time they went back to the drawing board, but I suspect whoever set this up has absolutely no idea what a drawing board is.

We have been paying for all meter exchanges for decades..I never heard a whimper of complaint from anyone on here when, for no logical reason , they started exchanging Imperial meters to Metric meters.
Not one complaint from the smart meter moaners when token prepay meters were all exchanged, also at great cost, to smart key and card prepayment meters, which turned out to be no better than the old meters
No one complained about the huge costs of quarterly meter reading teams knocking on doors all day. All paid for by the consumer.
As you say.."emphatically not free "..why did nt you complain then ?

Nick's site brings up some good points that should be taken into consideration. Bear this in mind, someone with the time, resources, and money who can spend 10 years infiltrating the design and adding exploits to the energy network would also be someone who could probably just pay someone to do similar things with wires on balloons.



Turning off your power has a good point and a bad point.
If the grid fails and areas are having surges and dips... The DNO could turn homes back on slowly to avoid a cascade. In a digital home this could mean thousands of devices don't get damaged during initial power on. The bad points are that some evil people could hack the system (yea, so likely), and that a energy supplier could just turn your power off due to non payment. Of those two, the non-payment one could be a problem as sometimes energy providers really get the billing super-wrong. My Npower bills would go from hundreds in credit to hundreds in debit and back to a few hundred in credit - all on the same day, so I can see mistakes happening. I think this is why it's been said that it will not be allowed.


Don't worry about the grid going pop by rogue organizations. The Gov will have it destroyed long before they succeed.

It got me thinking that there was a problem(there still might be) with electric key programmer(s) falling into criminals' hands with illegal top ups'.Could the same not happen to an engineer's smart meter's laptop falling into the wrong hands as well ?There is always a disgruntled employee that could do the same.

Its only my opinion but I am beginning to distrust this system,its bad enough with an ill configured smart meter not deducting credit,that got me thinking also is this the reason why people complain of sudden steep increases in their bills' after one of these meter's are fitted?We've seen in the press/media for eample.

SSE glitch: 'Smart meter said I owed thousands'

My supplier (British Gas) didn't pick up on my meter problem until I reported it.These are certainly someting to watched as undoubtedly more news/incidents' begin to surface.
