UK Power Smart Meters

I came across one of these the other day – a smart meter that had been fitted.

These supposedly get rid of the need to read your meter or have a meter reader come over and read it for billing. It also, they claim, allows the energy companies to more accurately predict demand and control supply.

It seems that it communicates, somehow, as most mobile reception was pretty unusable at the location, using GSM on the Telefonica / O2 network.

Far more information is here. Some other areas of the country don’t use GSM and rather use some sort of Mesh network setup by Arqiva.

The setup I saw seemed to use a Trilliant box, Model: SEAP-2000-V. As far as I can see it managed the communications with the GSM network and also with the wireless gas meter and the display for the customer in their living room. HAN probably means Home Area Network.

Along with the more interactive display in the house they also had a more traditional meter and display.

Interesting stuff, makes me wonder what happens if you break open the GSM unit and nick the SIM card.. what stuff is accessible!

Update: December 2016. A business smart meter 3 Phase installation!

This one is an EMDI Atlas Mk10D seemingly installed and maybe managed by G4S. The GSM aerial is stuck, externally, along the bottom of the unit.

Update: Summer 2019. A newer Landis Gyr installation..

This time the new installation has the same model as the first one in this article of “Landis Gyr E470” but the chassis and layout of the box is entirely changed!

Also the managed GPRS / GSM M2M device (to the right) is slightly changed but in the same form factor and layout. This time it’s a “Trilliant SEAP-2001-V” model.

Update: Summer 2021. A business install EDMI ES-10B meter! “SKU2 Cellular + Mesh”.

Update: An install from September 2021 using a Kaifa MA120 and Toshiba SKU2 Cellular + Mesh comms unit.

    What does wan Han and pwr mean please tell me I really want to know

  4. Wan = wide area network (the cell phone service or similar it uses to connect to your energy provider)
    HAN = Home Area Network (the ZigBee? Protocol used to connect to the smart energy usage screens and gas meter in your house).
    Pwr = almost certainly means the device has power .

    Hi. Are you able to explain why all my lights on my Trilliant Hub are flashing (and also emitting a buzzing noise).
    Thanks for your time

  6. Sorry, I don’t know the answer. Probably try your energy company community forum if they have one.
