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.

She said that they would only fit a flying lead if I had a 3-phase meter ...
  

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

 

I have absolutely no idea lol! Atleast the jobs booked in! =]

So are 4G comms hubs now commonly available in Scotland?

I’d like to be able to get mine working and 4G will likely be the answer with no WAN

They are indeed available, but currently being prioritised for RTS migrations

Just following on from my previous posts, the OVO engineer came out today. He fitted the fly lead but the commissioning of the electricity meter still failed at the last hurdle. He said that 4G comms units cannot be fitted in the northern region, as currently these are only permitted/allocated for RTS migrations.

 

So basically, I’ve run out of options in getting a working smart meter (and EV charger installed) unless something changes higher up the chain or the regulatory landscape changes to allow 4G hubs to be fitted in situations where LRR has failed.

 

I know this is an OVO forum, but does anyone know of any energy supplier that will fit a 4G comms hub where LRR has failed, or am I doomed forever?

AFAIK this is a DCC decision, so you’re VERY unlikely to find any other supplier who will fit the 4G Hubs at the moment.

@localshop this is frustrating, I’m sorry to hear this.

 

@Blastoise186 is correct in what he’s saying, however there’s nothing stopping you from contacting some other suppliers to see if they say any different. Let us know how you get on if you do.

What is the timescale for replacing all the remaining RTS devices in Scotland with 4G comms hubs? How many have already been replaced and how many are still left to do? Will Ovo customers with no smart meter signal to/from the Arqiva network have to wait until *everybody* else’s RTS is replaced UK-wide, or only until just Ovo RTS customers have been provided with dual comms hubs?

Hey ​@Ovolteeny,

 

The switch-off for 2G and 3G networks is not scheduled until 2033, so there is still ample time to replace communication hubs for our customers. We are currently focusing on our most vulnerable customers first, specifically those who use pay as you go services and are on the Priority Services Register. Once we've ensured that these vulnerable customers have received their replacements, we will then arrange to open allocations to the broader network of customers.

 

I hope this helps!

So here we are, almost 6 years on from having this meter installed. Ovo had another go a couple of days ago. A very nice engineer came round to do the gas meter, but admitted that he had to get the electric meter working first. So he tried replacing the long range radio meter with a 4g model, despite having a mobile signal it still doesn’t communicate. So still no go and he went home without touching the gas meter.

It seemed to me that a possible solution was missed. The engineer had a ‘hotshoe’ that could be fitted to the gas meter, I had the impression that this would improve the comms between the gas meter and comms hub on the electric meter, a notorious weak point, but no - the hotshoe enables the gas meter to talk to the DCC without going through the electric meter hub. Since the gas meter is higher up in our house this might work - and then the electric comms hub might be able to send it’s data via the gas meter hotshoe. 

I am going to raise a complaint again to see if this new compernsation scheme will give me some comfort. 

Meanwhile in France, the solution of sending the info back down the supply wires is working fine, the whole country has a smart network and no scandals yet about security lapses.

Hey ​@bingbongovo2021,

 

I'm really sorry to hear that you're still having trouble with your gas meter replacement. It's great to know that our engineering team has been putting in a lot of effort to help you out. I can totally understand how frustrating it must be when things don't go as planned, especially when the meter isn’t sending any signals, fixing that can be tricky.

 

While raising a complaint might not lead to a resolution since the lack of communication is somewhat out of our hands, you’re always welcome to reach out to our complaints team if you'd like. They can liaise with our engineering team to get a better understanding on what's required.
