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.

Morning ​@bingbongovo2021,

 

Thanks for letting us know - that’s great news. I’m sorry you had to wait this long to get it all sorted, and sorry as well for the initial experience you had in May during the engineer’s visit.

 

I’m just tagging our Metering Expert ​@Lukepeniket_OVO here so he can see this one’s all sorted and pass on the feedback.

 

I hope you have a great weekend and, if you need any further info on your smart meter or IHD, there’s plenty of articles in our Library section here.

 

As always, let us know if you have any other questions about your meter, or anything else related to your account.

An Ovo engineer … realised that a smart meter installed in Febraury 2021 would not have the firmware required to talk to a 4G comms hub installed in 2026. Changing the meter fixed the problems immediately and everything fired up straight away.
   

Thanks for wrapping this up so neatly 🙇‍♂️

I have one little question for you: what was the make and model of the meter that was exchanged? And of the new one? 

I ask because I’ve come across elsewhere similar problems with one particular sort of meter and its firmware, so I’m interested to learn whether yours is another case to add to the list.

Hi, The old meter was an Aclara Kaifa SGM1411-B I think. I don’t know the make of the new one and I can’t find out because it’s hard to get at. I hope that helps.

It sounds like you actually had an Aclara SGM1411-B - Kaifa doesn’t make that model. Did the Kaifa thing look really skinny by any chance?

In pictures it looks like one unit. It had Kaifa on the top left and Aclara below. But maybe the Kaifa and Aclara bits were seperable. If the Kaifa bit was indeed separate then it had Adaptor FL100 on it.

OK. I can’t see why you would have thought I was not describing my old setup, of which I had pictures because I had to read it with a camera on account of it being pretty inaccessible.

I did say that one engineer had moved the comms hub a few inches, so the Kaifa thing allowed that, it is obviously designed to attach to the meter so that’s why it looks like one unit.

I’m afraid I’m not going to go through the hassle of accessing the new meter and hub, it is a real pain to do so which is a big reason as to why I have gone through this whole smart meter story. It has been a lesson in poor specification and especially incredibly bad liason between the people who are supposed to fix the problem. We as a nation must be paying a huge cost for having the electricity infrastructure owned and operated by so many disparate companies.
