S2 smart meters in the Northern Territory using the Arqiva network - why isn't the meter able to connect to the WAN?

It’s been a long story… Some while ago we were offered a SMETS1 smart meter, but we delayed until a SMETS2 was available. Then an engineer came to install a SMETS2 meter, and left saying something about no signal, leave it a while. The meter is in a lower ground floor area, with a mobile signal.

Finally, July 2020, new SMETS2 meter installed - not talking to the network, but wait a bit and it’ll ‘probably’ be OK. No IHD left. I thought that even if the thing couldn’t talk to Ovo at least an IHD would allow me to read the meter easily, so I requested one, which eventually arrived. Silly me, I didn’t realise that the meter - supposedly installed for MY benefit - wouldn’t talk to my home network if it couldn’t talk to OVO first.

After a while we got back to Ovo who said there was nothing they could do and we would have to move our meter, at our expense (approx £250) and hope the new position had a better signal. No guarantee of that. Then I asked for a smart gas meter, reasoning that the gas meter - in a higher location - may have a better signal. I didn’t know then that the gas meter unit will only talk to the electricity  meter unit.

A really nice and helpful chap came round to fit the gas meter, but actually spent all his visit trying to get the electricity meter unit working. After every possible effort he was forced to admit defeat and we are back to zero. But he did give us lots of interesting information.

Apparently the SMETS1 communication unit didn’t HAVE to be fitted right onto the meter and had a little aerial to help communication, seemed a good idea, why did that not make it to SMETS2?. Also the country is split in 2, the southern half has meters that talk to the mobile network - but up here in Morecambe the meters talk to a network run by Arqiva, who don’t talk to Ovo’s customers. Apparently signal problems are reported by the engineer to Arqiva, who should solve them - so why did Ovo ask US to move our meter?. 

But why can’t the stupid thing pass the data to Ovo via our home network?. Our home is full of things that talk to the world and don’t need Arqiva to do so. At the least it should send it’s reading to the IHD, I’m totally capable of taking all the data I need about saving energy from a meter reading thanks. 

So finally I’m going to fit a camera up to send me the meter readings, and when Ovo decide they would like the smart meter working then they can come and install a unit designed a little bit more intelligently and with a bit of flexibility. It might be more expensive , but would save them money in repeated engineer visits, and certainly cheaper than moving the electricity meter.

Our meter, or the comms unit, is an EDMI standard 420.

I hope this helps someone.

I’m afraid it’s not possible for smart meters to use the internet to submit readings. As part of the specs, it all has to go through dedicated and purpose-built networks. There’s more details about how it all works over at SmartMe. We use this resource on the forums a lot, as it helps us out a ton!

As you mentioned Arqiva, that confirms you’re in the Northern Territory. Unfortunately, the EDMI comms hubs used up there don’t support external aerials.

 

 

There doesn’t seem to be a set process of what happens when the meter doesn’t talk to Arqiva, which to me is wrong, there should be a defined fault recovery process which always ends up with a satisfactory outcome.

 

We’ve taken this one to team who’ve confirmed the usual process following us installing a smart meter which can’t receive a signal on the Arqiva network. In this scenario we should report this as an incident to the Data Communications Company (DCC) who are then responsible for contacting Arqiva to improve the WAN signal in your area. The issue is then between the DCC and Arqiva to improve the signal coverage, all we can do is flag it accordingly - the infrastructure is not within our control.

 

Once we’ve raised the issue to the DCC it can take up to 6 months for them to investigate. We may be able to schedule an engineer’s revisit once the 6 month investigation period is up, however there’s no guarantee things will be working at this point. It’s worth mentioning that even without a signal your meter will continue clocking your usage and readings can be taken manually and submitted on your online account.

 

Sorry to hear of the advice you were given to pay for a meter relocation to resolve this issue. We should only be suggesting this as a really last resort option if the meter is in a particularly poor signal location, and all other attempts to improve the signal to the meter have failed. 

 

Whilst we’re really interested by the discussion this topic has sparked, it's worth mentioning that as a supplier, we are limited in terms of the way smart meter networks function and the security implications of using alternative methods to receive your usage data.

I suspected as such. It’s an S2 Landis+Gyr E470 Type 5533 with an EDMI Standard 420 Comms Hub for the Northern Territory. MapleCo was just the Meter Asset Provider/owner of the meter.

Getting a Flying Lead on that thing? Piece of cake!

Thanks for the reply.

Two things, do you know what the name/model number of the flying lead compatible with my setup is and what is the best way to request this from OVO? Hopefully if I can get the CU higher in the cupboard it might commission successfully.

It’d be the same Kaifa one as others use - there’s only one model currently IIRC which is the Kaifa FL-100 Flying Lead.

If OVO thinks you need one, the engineer will provide one as part of the standard install/upgrade job. I’ll ask ​@Lukepeniket_OVO about whether you can have it retrofitted.

Hello,

 

yes L&G electric meter property of MapleCo (MAP) and northern CH. Yes a flying lead can be retrofitted =]

 

cheers

Thanks ​@Lukepeniket_OVO and ​@Blastoise186 

If that doesn’t work I’ve read that the engineer can potentially fit a 2G/3G comms unit, is that correct? I’m in the northern region but my very basic knowledge indicates that engineers have done this where commissioning is not successful via the normal LRR route. Would I just need to contact general customer support to ask this or is there a specific team I should be contacting? Thanks again!

You are correct but we would not try a 2G/3G instead we would try a 4G comms hub (to you itll look exactly the same but i needed to get the terminology correct). Were you previously a RTS customer as that route is usually limited to RTS customers but if you have any trouble when you call in let me know and ill see what i can do?

No I wasn’t an RTS customer, I had a dumb meter which was replaced last week with the new smart meter which unfortunately couldn’t connect to the WAN via LRR. I’ll try and go down the flying lead retrofit route first and then see what happens. Thank you for your kind offer of assistance if I hit a brick wall. I will update this thread as and when.

Security seal missing on the comms hub?
As it’s only been there a week then it makes me wonder if the engineer already tried some alternatives?

I said, Hey - Watts going on.

Just a quick update to say that OVO rang following my customer service request to fit Flying Lead, or if not a 4G comms hub. She said that they would only fit a flying lead if I had a 3-phase meter (which I don’t have). She said they might be able to fit a 4G comms hub, but that depends on the mobile data signal in my property. Anyway an engineer visit is booked for a couple of weeks time.

@Lukepeniket_OVO What is the thinking behind this odd condition, if any?
