Ovo energy supplier wants to fit Smart Meters but just like to ask if
there are any snags/watchit warning etc etc before agreeing (seems I
have a choice - which is nice). At the 'mo we jsut have the famous
spinning disc for elec and a gas meter.
I see they use a 'phone-type WAN to send the data to supplier - good
if secure I suppose.
People have probably got fed-up trotting out their pros and cons,
nothing has changed since the last time it was asked ...
Thanks - well i asked 'cos i don't live on ng's. But as I say, thanks
anyway for the link - and glad I took a look. To save anyone else
asking rsn - here's a few reasons from that link to NOT go for it.
I am getting one next week - complete with wi-fi connection to my
Does anyone have such, and any comments on it?
They want to use your WiFi and presumably net connection? Is this for
the meter operators useage upload and control of the meter?
F. that for a game of soldiers. If their system needs a 'net
connection they can jolly well provide their own or pay me £40/month
to piggy back on mine...
Even if it's only so you can see a pretty web page of useage WiFi APs
aren't free and your firewall/router will need a config change to
deny the the meter net access. You don't know how to do this (do
you...) so you are going to have "call someone out": £75 call out
charge (inc first hour and 50 miles travel) then £25/hour in 15
minute increments rounded up. Shouldn't take 'em more than a couple
Only 1/4 in jest...
Is this a fully smart meter ie one that lets OVO read it when they
to or simply one to inform you of your personal consumption visa your
I used to be with OVO but got out when they wanted to charge me £60 to
change to one of their newer tariffs. The charge was the same to move
another supplier and £30 cashback when I moved. Plain daft marketing
strategy on their part IMHO.

HA! so if these are fully smart meters, then they can cut you off
remotely. Having done so (maybe in error?) then there will be no wifi
connection to enable them to switch you back on!

The reason I wanted to use smart meter was to stop having to grovel
unders the stairs every month to read the two meters. (back troubles).
Let's say you stick a wifi equipped smart meter on your home network.
It has the ability to read every single wifi packet sent or received on
that network and it has the ability to connect to any device anywhere on
Is that really what you want?
99% of your security comes from your router protecting you from attacks
from outside. Normally it will only let through responses to connections
*you* have made.
99% of your wifi security comes from a password that means only devices
you allow to see your internal network, can see it.
Now stick on a box that you allow access to your wifi, and which is
fully connected to the internet?
And probably one that 'upgrades ' itself over the internet?
How ling before it 'upgrades;' itself to a hacked bit of trojan horse
that scans your home network for all the bank details and logins and
email addresses in use.
Of course its possible to build a firewall between 'appliance net' and
'home net' but who has the ability to do that?
If you tell a lie big enough and keep repeating it, people will
eventually come to believe it. The lie can be maintained only for such

You can tell they don't use WiFi because they will ask you what your
mobile reception is like but they don't ask if you have an internet
connection or even a phone line.
You can then safely disregard all the following.
OVO installed SM's here in June...
1. You know exactly what your consumption is second by second on the
2. You know exactly what your consumption was every 30min, per day, per
week, month recorded/ stored via their web site.
3. You no longer need to look at the readings and let them know, they
are uploaded every night.
They, or if hacked another, could cut you off in an instant. Risk tiny.
But does it really matter?
If someone were really that interested, my gas and leccy cupboards are
outside and if someone so desperately wanted to, the could sneak round
and get my readings directly. All they need is a 10p triangular key and

Way too labour intensive a way to be workable. A hacker & computer analysing 100,000 homes could however be profitable.
If there's one thing computing history teaches us, it's that some degree of paranoia is warranted with computer data. Of course some never learn.
Precisely, there are so many alternative ways to assess whether you at

When present there's lots of other consumption too. Not too hard to tell them apart.
