That's a good point @cswd
and I agree that the 'rules' for decommissioning a gas supply are unclear.

Technically Cadent is a Gas Distribution Network Operator (GDNO) or a "Gas Transporter". The term DNO is assumed to refer to electricity distribution companies.

Octopus is right to say that they may not remove a gas meter on a live pipe because that leaves the adjacent isolation valve in place. It's too easy for the lever to be moved, thereby causing gas to leak out at 'mains' pressure.

I would start the process by asking Cadent for the price of them 'capping' the pipe, rather than isolating it 'in the road'.

You are also right to highlight the cost of a household moving across to a 'net zero' heating regime with a heat-pump.
Government strategy has failed to alert the public, or account for, the costs of removing gas supplies to our homes.
75% of UK households use mains gas as their basis of heating.

Official Government strategy is to migrate the gas network to deliver hydrogen, which contributes no CO2 to the atmosphere.

It's difficult to see how that strategy can be carried out in practice.
You can't commit a home to use hydrogen until the network delivers it.
Either the pipework in an area carries natural-gas (butane/propane mix) or hydrogen.

It's impossible to gradually migrate an area from one gas to another!

We live outside of Brecon, with no mobile signal. We rely on wifi calling, and the wifi is provided by Voneus :
Question; A smart meter just installed by Octopus;  isn't working-and won't work- as there is no mobile signal (WAN) (it's a KAIFA MA 120)
Is there a smart meter that doesn't need a mobile signal?
The smart meter looks complicated but we weren't given any instructions. Is there anything useful I can get out of it?
Will anything change to make the smart meter communicate with octopus in the near future? Satnavs work fine around here.

Your location means that you are in the Central Territory of the National Smart Meter Network.

The Data Communications Company (DCC) has assigned the wide area network communications to Telefonica, who operate the O2 mobile network in UK.
Here's a screenshot of their GSM Coverage map with Pin-A for Brecon in the middle.
The other Blue pins are transmitter positions, spread along the valley floor.

The Wide Area Network uses a derivative of the 3G mobile system.
It operates beyond the range at which a mobile phone would be capable of sustaining a signal.

 

The KAIFA MA 120 you refer to is the Electricity Smart Meter Equipment (ESME).

Kaifa MA120

Bolted on top of that is a Communications Hub, which should have five green LEDs, of which at least four should be flashing every 5-seconds.

The Comms Hub has more than one variant, and yours has been chosen for your location by the engineer who checks a SMWAN Coverage Database prior to installation.
Most homes have a SKU1 version

CommsHubsSKU

The SKU2 version can optionally be fitted with an external aerial.

It incorporates two transceivers capable of reaching the Smart Meter Network.

When direct (line of sight) signals are too weak, the SKU2 scans the surrounding area to seek out any other SKU2 (or SKU3) Comms Hubs.
If it can find a minimum of three others, then they automatically form a Mesh Network.

Smart Meter data is passed across the Mesh Network until it arrives at a site where there is connection to a Telefonica tower.

My own house, on a hilltop in rural West Devon, has a SKU2 Comms Hub and an aerial stuck (literally) onto the outside of the external meter box.
That acts as a 'relay' for houses in the valleys to the west and north of my location.

SMETS2 E2sm

Instructions for reading a Kaifa MA120 ESME are posted on the Octopus website.

Shell can't connect to my meter (WR135DW). The IUD works OK but it can't "pair to the account".

I guess the oblong thing with cable is an aerial? Should I yry moving it ? We are in very bad mobile reception area ....

Hi @lenny - can we clarify a few points please?

Was it Shell who installed the Smart Meter?
It looks like it has been there many months. There's an archive of (expired?) spiders upper-right 😉 

What flash pattern are you seeing on the row of five LED indicators?
Compare this with the explanation I posted here earlier in this topic.

The oblong is indeed an aerial, although I haven't previously seen one placed that close to the Communications Hub.

Moving the aerial might be worth a try, especially as it's only hanging from one screw.

We don't know how your Comms Hub has been configured.

  • that aerial could be intended to increase the signal strength to the nearest Telefonica transmitter
  • or it might be used to allow connection to a Mesh Network operating in your area

 

The only GSM 'mobile' signal strength which you can compare with is that used for the O2 network.
Other mobile networks aren't relevant.

I think you might be referring to an In-Home Device (IHD).
An IUD is a contraceptive device and unlikely to be supplied with a Smart Meter.

Are you telling us that the IHD is receiving/displaying data from the Smart Meter's Comms Hub, but that the link to your Energy Supplier (Shell) is the only bit that's non-functional?

Thanks

First, I'll confirm that IUD is stored elsewhere with no spiders !

Second, yes, the issue is no connection to Shell (who did install the meter via third party installer). IHD works  and tbh I haven't bothered about the connection until now I have the PV array active and want to explore feed in tariffs.

 

I'll check the LED actions and maybe move the aerial

I had a smart meter installed by Octopus via a third party installer.  All went well (apart from the guy managing to break the hinge on the meter cupboard).

However the IHD has changed its display.  For the first week it showed amount currently being used on the left and a daily total on the right.  That then changed to the right hand display showing a notice informing that it is awaiting data from the gas meter.  This is annoying because the initial display was useful and informative.  We don't have a gas supply.  We aren't on the gas grid here in our rural location.

There's several unrelated points in that saga, @morgan !

First - the meter cupboard door.
If this is a 'standard' electricity meter box, then replacement doors can be bought separately.
There are a number of different types. Take a photo and email it to the supplier.

 

2: Smart Meter Commissioning

Once a Smart Meter Installer has completed the on-site part of the work, there are a number of other operations which still need to be undertaken remotely

  • the Data Communications Company (DCC) runs a series of tests; that allows analysis of signal strength for example
  • DCC informs your Energy Supplier (Octopus) that the meter passes the specification and is available to them
  • the manufacturers of the electricity meter, communications hub and In-Home Device (IHD) send firmware upgrades to the current versions
  • Octopus downloads the data for your chosen tariff into the Comms Hub; that gets reflected in the IHD

So those actions account for why the IHD looks different a week later.

 

3: 'Awaiting data from gas meter' is probably an error in your Comms Hub configuration.

We need to know if you are in Southern, Central or Northern territories of the UK.

So either give us your approximate geographical location, or else tell us whether the Comms Hub has five (green) LED indicators or two bi-colour ones.

CommsHubsTerritories

Then tell us what those LEDs are doing!

I’m in Derbyshire.

Of the LED’s SW, WAN & HAN are flashing intermittently.

Thanks for your help.

Thanks for photos. That's much easier for me to see what's happening.

 

1: The door looks like the lower hinge is no longer attached to the frame of the meter box.

If this were to happen to me, I'd use a couple of pop-rivets or self-tapping screws to reattach it.
If the frame itself had been damaged in the process, I'd detach the top-hinge too, invert the door and reattach it on the other side.

However, if you don't have the screws, tools or skill-set to do this, then it should be handled through Octopus' complaints service
Your contract is with them, even though the damage was caused by a 3rd party contractor.

I always recommend sending complaints by email because it then has a written record with a date/time stamp.
That gives you the evidence required by the Ombudsman in the unlikely event of your case going in his direction.

 

2: I see what you mean about the IHD providing non-existent gas data on the right-hand half of the screen.

I haven't previously met that design of IHD, but you should've been supplied with a manual.
If not, search online for the model number on the rear label.

There is probably a configuration setting to select what you wish to see on the screen by default.

 

3: The indicators are flashing as I would expect.

You have no gas or Mesh-network, so those LEDs are off.
That means the Comms Hub realises that there's no gas data to be sent to your IHD.

The Software, Wide Area Network and Home Area Network are using the slow-flash pattern, once every 5 secs.
That means all is OK.

@transparent Thank you.  Very much appreciated.

The manual you speak of 🤣 I will look for the model number and see if there's better information online.  The IHD was actually displaying correctly for the first few days with no reference to gas supply.
