On your forum people are having issues with there smart meters one person was still having trouble with the smart meter after six months you have all ready acknowledged that and you are working with him to fix the problem six months is to long another one is getting a fourth smart meter installed in November because the other smart meters where rubbish there is loads more on your forum who are having issues with there smart meters.

As I'm sure you can appreciate, @Ivor Appleyard, people tend to voice issues on a public platforms. You're right not all of the installations have gone perfectly, but the majority have.

We encourage people here on the forum to share experiences, it helps people to share knowledge and manage expectations. Hopefully the members that you've mentioned, with meter issues will be sorted sooner rather than later, we really are doing all we can to get things resolved as quickly as possible.

Thanks!

Well I'm most likely the one you refer to who hasn't had operational SMETS2 meters since first installation six months ago.

But I responded to your observation on another Forum Topic, @Ivor Appleyard, where I mentioned that I had agreed with OVO for them to run a series of software tests on my SMETS2 meters.

My account is well in credit and neither OVO nor myself are feeling any urgency to cease the tests and revert to me finally having a fully-operational installation with the online usage-graphs working.

In fact I'm just about to add another piece of equipment-under-test to my Smart Meter set-up. So there's not much point getting all the data-streams sorted where they interface with OVO's Billing-software when the SMETS communications at my site might get disrupted all over again.

It's this on-site testing which helps OVO decide whether it really is installing a "rubbish meter" as you suggested, or whether it's something much more subtle, such as the order in which commissioning is undertaken.
Conversation over.
Not good enough conversation over.

Hi @Ejclayton - well it certainly won’t be the current SMETS2 variety. So if it’s definitely “smart” (as opposed to “digital”) then it will be a SMETS1.

Is anyone even fitting smet 1 meters theses days ? 

Account No: *Removed by mod*

Awaiting smart meter install; will it enabled for off peak loads on my account No above?

I want to charge my ecar between 1am-5am (7kW)

Welcome to the Forum @0415

This is an interesting question because it doesn’t have a straight yes/no answer!

Smart Meters have a wide range of capabilities inbuilt into them, few of which are currently used. Those that I have investigated all seem to support at least four different preset charge bands.

However it is a function of your chosen tariff which dictates whether these charge bands are used. As far as I know, OVO currently offer just one tariff that makes use of an alternative charge band. Unsurprisingly it’s the one we call Economy-7, which provides a lower price for all use between midnight and 7am.

Contrarywise, those customers who opt for an OVO Economy-7 tariff will pay an increased rate for electricity usage outside of those times (ie higher than customers on a standard tariff). So whether it is viable for you comes down to what proportion of your energy consumption is required outside the Economy-7 slot.

 

All of this strategy for charge bands is currently being superseded by  half-hour variable tariff structures, sometimes called Time Of Use tariff.

This allows customers to draw energy at much reduced rates when it is in plentiful supply, for example from wind turbine arrays, but increases prices for usage when there is peak demand and little renewable generation available.

The Government’s name for this is Demand Side Response.

 

I have received the offer of an appointment for a smart meter but before I commit to a time there's no detail as to whether this is the newer type meter that will work with other service providers. I would want to know before I agree to an appointment so can you advise please?

@lkjasw if it doesn't specify throught the link then it may be best to contact customer service and they will be able to advise and book it in there and then

The answer depends on where you are situated within the country @lkjasw . I looked for this in your Forum Profile, but you haven’t yet filled it out.

In the Southern and Central territories of England and Wales, where Telefonica is the licensed communication operator for the National Smart Meter Network, OVO have been fitting the newer SMETS2 meters since 16th March 2019. They can no longer obtain credits from Ofgem for fitting the earlier SMETS1 meters.

If you live in the North of England or Scotland, then the situation is more complex. The telecommunications operator for the Norther Territory, Arqiva, uses a different radio frequency with extended coverage. But the installation of that network is running several months behind the rest of England.

In those circumstances, only OVO themselves can state which Smart Meter generation they are able to install.

I have updated my location, so yes the South of England. 

 

Appreciate the guidance, although I have already raised a question with customer services on the basis the information isn't readily available. 

 

I would have hoped that ovo would want customers to make an informed decision on this and should be putting this information front and centre rather than expecting people to make appointments without knowing.

I don’t disagree with you @lkjasw. But you are at least technically informed sufficiently to ask the question. I doubt that most consumers could even understand the difference between SMETS1 and SMETS2

If you look through the official OVO website, it actually has very little technical content. In keeping with most companies, most of their market share is obtained by using marketing tools to encourage “sales”.

I feel you actually get better responses to your sort of enquiry from this Forum. There’s quite a few knowledgeable correspondents here, and we’re not constrained by company policy!

I’ve been discussing with one of the Forum Moderators, @Tim_OVO, how we can better allow readers to find the answers they’re looking for here.

For the question you’ve asked, the answer actually changes over time. So when reading a Topic, you need to note when each comment was first uploaded. Perhaps we need to consider some of flag-system so that we can still retain earlier comments, but add a symbol to alert others that the information has now been superseded.

Yes I agree and had seen an original thread which was two years old and as you say this is a moving feast. 

 

Ethically it would be better for companies such as OVO to take the lead on being informative. I guess someone posting the message on the app elected to not be informative... Which is a shame.

We have to remember that OVO is now a very large company and has senior managers overseeing what the web-designers, marketing team and advertising specialists think will most attract the highest number of potential customers.

Unfortunately, the level of detail that you and I enjoy delving into isn’t particularly attractive to the majority of people they are trying to reach.

This is going to become a serious problem in the domestic energy sector, and it’s one that Ofgem are eager to address. They cite “lack of knowledge” as a key factor in holding back the forthcoming technology on which the UK energy strategy is based.

For example, here’s a diagram from the final version of a BEIS leaflet explaining how Smart Meters deliver the Demand Side Response strategy for which the UK Government passed the necessary legislation in 2013/14.

 

To me (and possibly you too) this is very informative. It explains where the Smart Meter sits within the secure control system which allows me to optimise my electricity use for when energy prices are low.

However, the vast majority of the population still only regard a Smart Meter as a mechanism by which Energy Suppliers can send them accurate bills.

Even OVO’s/Kaluza Division aren’t using the secure SMETS Command Structure to control their two intelligent Electric Vehicle Chargers!

Somehow we have to overcome this knowledge deficiency and allow people to see the possible energy-efficiency measures they could be using to lower costs, increase the quantity of renewable energy in the mix and help combat Climate Change.

Then, like you, they might actually ask the (highly relevant) question about what generation of Smart Meter they are being offered.

I think all of us have a part to play in spreading the little knowledge we have to as many people as we can. SMETS Meters need to become a conversation topic in the pub and the gym.

 

(And BTW, you don’t need to re-quote what anyone else writes when you reply to it within the same Topic. The QUOTE button is a bit too prominent on the Forum. We need a Moderator to have a look at that issue in the Forum software… @Nancy_OVO ?)

@Transparent thanks for sharing that diagram... Certainly is interesting to see.

 

So, as someone who is clearly better informed than I am, would you recommend installing the SMETs2 or do you think there may be another iteration that may offer even better connectivity and energy management?

Oh you’ll definitely get a SMETS2 @lkjasw. There’s no SMETS1 meters being installed at Stowmarket in 2020!

If you want to learn a bit more of what this entails, have a look at the Topic I’ve been writing about SMETS2 Installation.

The concept of controlling other devices from the Smart Meters is called Auxilliary Load Control Switching and you can read a bit about that here later in that same Topic.

My smart meter serial number begins 18K - other posts say that the letter denotes whether it’s a smets1 or smets2.  Since mine begins 18 (year of manufacture), I’m guessing that it must be a smets1.  Could anyone confirm?  thanks, B

I don’t think SMETS2 meters were being installed in 2018, @brandas, but SMETS1 meters we can communicate with usually have the letter P. 

 

Post your MSN (Meter Serial Number) and we can check this for you!

No… @Eva_OVO you give up too soon.

Let the rest of us play a bit longer. :slight_smile:

Give us another clue, @brandas - What manufacturer’s name is on the meter? :thinking:

Thanks for replying - and so quickly!  My meters (gas & elect) are manufactured by MapleCo1: the gas says it is an elster themis (I assume that’s the model) and the elect says elster AM 110R.  They were installed (SSE customer) end of May 2018.  The elect meter serial number is 18K0008941.

Had I realised at the time the incompatibility issue, should I wish to switch supplier,  I would not have gone ahead.  It’s looking as if changing supplier will result in regressing to needing to send in meter readings either by phone or online - which defeats the object of having them in the first place.  Oh dear!  B

I’ll leave this one for you, @Transparent! ;)

Thanks @brandas - Elster is a meter manufacturer, now wholly owned by Honeywell.

It is unlikely that OVO can directly read your meters at the moment. However, all SMETS1 meters are to be upgraded to the newer SMETS2 software later this year. At that point they can be connected to by any Energy Supplier of your choice.

 

There are two other possibilities.

1: As you may know, SSE’s domestic customer division has been taken over by OVO. Although I don’t expect OVO’s software engineers to spend time linking SSE’s Smart Meter Network to OVO’s Billing system, it is at least technically possible. After all, both of the networks are now managed by OVO.

 

2: Elster do have two Smart Meters approved for SMETS2 upgrade and adoption onto the National Smart Meter Network. See the website of SmartMe from which I obtained this screenshot:

 

 

The model AS-300P is an electricity meter, whilst BK-G4E is for gas.

Neither of these model numbers matches the meters which you appear to have. If it transpires that Elster/Honeywell are not going to issue any SMETS2 software upgrade for your meters, then your current Energy Supplier is obliged to exchange them for new SMETS2 meters.

I’m re-tagging @Eva_OVO with a request that she draws the attention of OVO’s Smart Meter Engineering Team to what I’ve just written. They should be able to confirm this point.

 

Let us know here if this has adequately answered your original question, or whether you’d like further clarification.
