he EU6/EU6V meters are part of the established Liberty family of  
products offering reliable and secure ?token-less? pay-as-you-use and  
credit options. In addition, these meters offer the option of remote  
communications and can be used for AMI/AMR data retrieval, remote  
consumer management and remote valve closure in emergency situations.

Two variants:
EU6v - prepayment/credit with shut-off valve
EU6 ? credit only, without the shut-off valve.
Based on U6/ 2-litre BS EN: 1359-compliant product with Ofgem approval.
Meets PRS22 Type N, Zone 2 approved.
Electronic prepayment using the Liberty keypad entry technology via an  
in-home display or via GSM
10 year battery life from a replaceable D-cell
Interrogation via an optical 1107 port
Optional pulse output
Valve opening operation approved to Safety Integrity Level 2 (SIL 2)  
using manual intervention
Tamper logging includes:
Magnetic fraud detection
Tilt detection

The system can be configured to close the valve on detection of tamper

funny thing is that the meter will shut services if tampered. DOS
anyone?

I thought it was illegal/generally not done to turn off someones
services without a lot of effort to resolve an issue first. A supplier
could get in all sorts of trouble for shutting down someones
electricity and turning off some vital, life saving, device.

When the first granny dies of cold in the winter because her gas and
electricity were accidentally turned off remotely the stuff will
really hit the fan.

the meters in western PA use an inductive probe mounted on the
outside
of the home. the utility worker has to make contact with the probe
which gives the relative position of the meter gauges.

The power company has been testing some electric meters that  
transmit
the data back via the power grid.

I decided to research the meter shown on the video and its kinda
cool.
they can shut service remotely, you can pay from its keypad,  
seems to
have all kinds of tamper protection. im trying to get ahold of a  
tech
manual

I can see a whole load of hackers getting into trouble with these
meters. Traditional hackers just out of curiosity and nasty hackers
from trying to defraud the system.

I guess the cash saved by removing call centres and guys in vans  
will
probably make up for the loss of revenue for the few people who do
manage to hack the system.

Let us know what you find out.

Hi
Some utility providers are looking at rolling out smart meters for
gas
and electricity which they can read remotely. Does anyone know how
that works? What are they using to connect to the device to send  
out
the data? If it is over your broadband then it won't be long till
someone sniffs the packets and sends fake readings back, if it is
wireless and they have a guy drive past then there are similar
sniffing problems, you also have to worry about interference. They
could have a GSM card in, in which case, how long till someone
cracks
one open and tries to use the card in a phone, I imagine it  
would be
locked to a single number but people would try.

I can't think of a secure and problem free way to do this. Any
ideas?

Here is a BBC video about the meters.
