Landis+Gyr Smart Meters - Which Enery Providers

nxdmsandkaskdjaqd

I have just found out that my newly installed Smart Meters installed by British Gas may become Dumb when I switch energy providers.

I have Landis+Gyr E470 electricity, Landis+Gyr G470 gas and a Trilliant SEAP-2001 Communication box. From my reading so far I understand that 1st generation meters may not always work with the national communication network (DCC).

I suppose my first question is, are these boxes 1st or 2nd generation meters.

2nd question, I need to switch energy suppliers and would like to maintain the functionality (particularly the energy display meter installed within the property), therefore can you tell me which energy suppliers theses smart meters work with?

Many thanks.

It's not neccessarily the make of smart meter it's the communications protocol that the various suppliers use and how they gather the data so even if they used the same meter it still probably wouldn't communicate.

There's no reason why the In Home Device shouldn't keep working if you change suppliers but you won't get info sent abck and forth to the supplier, so you still need to read the meter.

AFAIK the BG meters will work with Sainsbury's Energy (as it's supplied by BG anyway) but that's all.

Others may know different

The E470 should be SMETS2 compliant and work OK when the DCC go s live.
The G470 gas meter is the second generation L and G smart meters and will probably need a module change.
The 3 rd generation L and G smart gas meter is the G370 smart ultrasonic zigbee which will work fine in SMETS2 as will the Trilliant hub.
Look on the back of the IHD ecometer to see if there is a sticker saying "Zigbee certified product ", which will make it fine with SMETS2

Unable to see if there any Zigbee markings, and have now contacted (Green Energy Options Ltd) them asking the question.

Geeen Energy Options responded in a few minutes and confirm Zigbee IHD

I,m ok with taking reading the meter, but as stated need the functionality to remain on the In Home Device.

This leads to another question as to how these Smart Meters work.

1. Meter gatters usage data and passes this via a Wide Area Mobile Network to energy provider.
2. Smart meters passes usage data to In House Device (IHD) via Local Area Network.

If the above is right, how does the IHD know the actual suppliers specific cost of energy to display the correct £ cost on the IHD?

As far as I am aware the supplier has to upload tariff info via the Meter to the IHD and when tariffs change, change them on their Smart Metering systems.

I think there's a comm channel back to the meter from the supplier otherwise a lot of the functionality wont be available.

Mine has the unit rate which I can see but can't change and tells me how much I owe at the moment which accords pretty well with my own figures.

We've only got leccy and the meter is an Elster A300P which communicates with the IHD on Zigbee channel 12.

Dunno if it's going to be SMETS 2 compatible but I suspect that wil be a function of the communications module which may or may not be replaceable or re-programmable.

I'm not bothered really. It works as a smart meter and it won't inconvenience me much if it reverts to a dumb one as I read it myself weekly anyway.

But presumably it wouldn't know your new unit rate so would either:

(a) continue monitoring at the old rate with BG or
(b) monitor usage only and not provide a cost, simply the rates consumed

Unless there's some way of over riding the unit to amend the unit rates.

Interesting thread and I never realised that the smart meters/comms weren't standardised across all suppliers. I despair at this kind of stuff!

I have recently installed British Gas smart meters (Gas E6S.. and Elec Z17...) and now wish to switch to Ovo via MSE energy club. However the form ask for the MPAN number and provides a 13 digit standardised field for you to enter it into. Obviously my new gas smart meter number does not fit that format so I can't complete the switch form.

Can anyone offer advice on this?

Your MPAN doesn't change when you have a Smart Meter installed. If you are unsure of your MPAN contact your current supplier, they should confirm it for you.
