No, voltage isn’t recorded by Smart Meters.

Perhaps it should’ve been in the specification. The power is recorded, and is then used by DNOs to assess the loading factors on their transformers.

Thanks - that confirms my impression. Obviously, voltage is measured internally, but it may or may not calculate the RMS voltage from it. I have never seen a power meter that could not display RMS voltage, but it seems that we have managed to specify it. Oh well, that is going to come back and bite us when we want to move to a smart grid.

Anyway, after a day of 250V+, the voltage has settled down back into the 24xV range. I can live with that. 

 
 
 

Hi. I have to do a Reading meter. I have a smart meter-one rate. I press 9 and there is IMP REG and the value and after that is IMP KWH and the value. Which number should i send them?

Heya @Carola2611 !

Good question there. The one you’re after is IMP KWH which is short for Import Kilowatt Hours. The other one IMP REG isn’t relevant for submitting meter readings.

Hi @Carola2611,

 

Looks like you’ve got a Secure S1 smart meter there. @Blastoise186 has hit the nail on the head with this advice -

 

 

The one you’re after is IMP KWH which is short for Import Kilowatt Hours. The other one IMP REG isn’t relevant for submitting meter readings.

 

You may also find our guide to this meter helpful so I’ve moved your comments over here. Check out the information above and let us know if you need anymore help getting to grips with your smart meter, we’re always happy to help! :blush:

We have a series 1 Liberty 100 electricity meter fitted by OVO. We are not currently supplied by OVO. Previously I was told to use the reading reached by pressing button B and taking the reading after Using Now and this has been accepted by others. I am now being told to press button 9. This gives a reading which is around 2500 units higher. Why is there such a difference between the readings. The Using Now reading as I recall aligns with consumption before the meter was fitted

Hi @Dc1789 button 9 scrolls through the various readings. The one you require is the number displayed after it cycles past ‘IMP KWH’. This is the import reading.

This SMETS1 meter should now be readable as a smart meter with a lot of suppliers, so if you are still being asked for readings it may be worth looking around to get this automated (and possibly a cheaper tariff in the process!)

Thanks. My problem is that the IMP KWH reading (19667}is 2500 units more than the Using Now reading(17188), which is the one everyone has accepted and told me to use till now. As I have just switched providers,using the U N reading, that presumably will mean a serious cost hike. So if I am to use IMP, what is the Using Now reading for?

I’m not sure what the B button shows. Hopefully a more knowledgeable person on here may be able to say. I believe the A and B buttons are generally used for prepay settings.

It may be worth checking your bill for the period when the meter was installed as this should show the final reading of your old meter and then the consumption of the new meter (which usually starts from 0kWh.

If and when your supplier manages to remotely read this meter it is likely that they will get the IMP kWh reading shown on the display by button 9. This assumes that you are on a single rate tariff. I believe if you have multiple rates such as day and night, the individual readings can be seen by cycling through the readings using button 6. It may be worth checking this to make sure there are not two sets of readings that add up to the total (19667) and the using now reading is only displaying the current active rate.

Thanks. Will try that. Don’t think I have multiple rates though which I am assuming is something like economy 7 which we don’t have.

Thanks @nealmurphy ! Your answers so far are pretty much spot on as far as I can tell. Thanks for helping @Dc1789 out so far. Even if you’re no longer with OVO, we’ll always be happy to help you out on the forum completely free of charge. You won’t get any marketing emails from OVO just by being on here.

IMP KWH is generally supposed to be the reading you’re after if you are on a Single-Rate tariff, but I know a trick you can do. If your meter is communicating properly with your new supplier, you can ask them to pull an Instantaneous On-Demand Reading using SMETS Commands to grab the current reading. Not only can they tell you what the reading is when the meter responds to the command, but you can also ask for that reading to be logged to your account as that days reading too.

Once you know what that reading is, you can compare it to the one that’s on both Usage Now and IMP KWH to see which one matches up with the SMETS Commands. That’ll be the one to rely on going forwards. :)

Thanks. Will try that too.

Hi @Dc1789 and welcome to the OVO online community.

 

Great question to ask about reading your Liberty 100 smart meter. Our amazing community members are already on it in terms of offering some really sound advice - 

 

 

button 9 scrolls through the various readings. The one you require is the number displayed after it cycles past ‘IMP KWH’. This is the import reading.

This SMETS1 meter should now be readable as a smart meter with a lot of suppliers, so if you are still being asked for readings it may be worth looking around to get this automated (and possibly a cheaper tariff in the process!)

 

If your current supplier hasn’t been able to receive the reading automatically (and there’s quite a few who should be able to - find out more here), you’ll need to press the ‘9’ button to read the meter manually. According to our Liberty 100 guide (which I’ve moved your comment across to) the ‘B’ button “ Activates auto scroll display from sleep mode; used to scroll back through a display sequence; initiates UTRN(vend) authentication process; mutes alarm; used to confirm supply reconnection from ‘READY’ state.” So I think @nealmurphy is spot on in suggesting this is more relevant for PAYG customers.

 

 

 My problem is that the IMP KWH reading (19667}is 2500 units more than the Using Now reading(17188), which is the one everyone has accepted and told me to use till now. As I have just switched providers,using the U N reading, that presumably will mean a serious cost hike. 

 

 

Sounds like the opening meter reading you’ve supplied might be incorrect. When you give this reading to your new supplier it’ll be ‘validated’ - whereby the industry checks this reading lines up to the previous readings. As this reading will be out-of-line to the smart meter readings which should have been sent automatically this should be flagged during the validation process. It’s worth checking the first statement you receive from your new supplier as the reading may have already been corrected. If not your new supplier can raise a ‘Read Dispute’ to get this corrected and make sure there’s not a leap in your charges. You can read more about the ‘Read Dispute’ process here

 

Hope this helps get this sorted, if not pop back with any more queries - we’re always happy to help! :relaxed:

Please bare with me as I am terrible at explaining things!

So I have been giving manual readings from both my gas and electric smart meters as for some reason there is almost no connection. My gas meter has been absolutely fine, however, my electric meter seems to be playing up quite a bit.

Every 1 to 3 weeks at least I have been giving readings of 14***, now 15*** but on 13th July my smart meter sent a reading randomly of 11***. That is such a big difference and I haven't been able to send the reading I have been getting as it is too high and its not accepted.

I have emailed and was told that I have been giving a total reading and to look for a number starting with 11. I have been through it a fair few times and see no number that is anywhere near that.

Is it possible my meter is faulty or am I doing something wrong?

Welcome @Hannahbunve ! :)

I can definitely see what I can do here. Please could you snap some photos of your meters and pop them in your next reply for me? I’m definitely happy to help you work out what’s going on here and once I know what meters you have, I can provide the right info to make sure you’re getting the right readings.

Of course! I feel like I need to include (although I likely don't!) I am pressing button 9 and reading the first set of numbers after IMP KWH. 

Here's a couple pictures of our Electric meter, the gas one is absolutely fine. :)

No worries. :)

You’ve definitely got a SMETS1 Secure Liberty 100 electric meter there, which means the gas meter will also be a Secure Liberty as well. You are definitely pressing the correct button as 9 is the one to grab a meter reading from this meter model under IMP KWH. If you have Economy 7, you’d also need to press 6 three times to get the Night Reading from IMP R01 and press 6 again to grab the Day Reading from IMP R02.

If you happen to have an In-Home Display as well, you might be able to grab a meter reading from that instead of fiddling with the meters. The Secure Liberty meters aren’t as user friendly as Aclara and Flonidan meters, but they’re not too bad. Your IHD should be able to grab the meter readings under something like Meter Info - which is where I can get my readings from using the Kecleon Brothers (two Chameleon IHD6).

If you're still struggling, ask the Support Team to try running SMETS Commands to grab Instantaneous On-Demand Readings from both meters. Not only should this provide the correct reading, but you can also ask for these to be logged to your account as the current reading as well. There’s no charge for this kind of request and if it works, the meters should usually respond within about five minutes or so.

Next time you contact the team, please let them know about this thread and tell them that Blastoise186 has been helping you out via the OVO Forum. Sometimes good things can happen when you do that. :wink:

It might be possible that your meters are also being migrated to DCC to run under the National Smart Meter Network right now, after which they’ll run as “SMETS1+” and should work with any supplier freely. But this can take a while to migrate and in some cases, the connection might drop out during the process.

Have you ever had readings go in from the meters? It might be worth increasing to either Daily or Half-Hourly Mode to boost your chances of getting Smart Readings in more reliably and you’ll be able to spot issues more easily. If there are persistent comms issues, the team can raise an escalation to have this investigated more deeply and OVO can attempt a few fixes that may help get things going again. You won’t have to pay for any of these fixes - they’re complimentary and included as part of the service. Unless you smash up the meter with a baseball bat that is! You would have to pay to repair deliberate damage or vandalism - but I highly doubt anyone would do that!

Hi @Hannahbunve and welcome to the OVO online community!

 

Sounds like your Secure S1 meter is (or used to be) Economy 7, in which case our community volunteer @Blastoise186 gives some great advice in how to take the reading - 

 

 

If you have Economy 7, you’d also need to press 6 three times to get the Night Reading from IMP R01 and press 6 again to grab the Day Reading from IMP R02.

 

Have you checked your meter’s reading schedule with the Support Team? Requesting an update to a daily or half-hourly schedule will mean you shouldn’t need to read the meter manually, although we’re on hand here if you notice any communication issues.

 

If you haven’t already it’s worth checking the usage pages of your online account or OVO app (download for Android or iOS) which shows the usage info we’re receiving from your meters.

 

Hope this helps - let us know how you get on! :slight_smile:

Oh my..I feel silly 🙈 I have checked pressing 6, and it gives me the reading I need. I didn't realise at all it was economy 7! 

 

Thank you all for all your help! I appreciate it :)

No worries @Hannahbunve ! I’m glad we managed to solve that puzzle for you. :blush:

I do have some advice that I’d also like to throw in as a free bonus as well. Not least because I like giving people free stuff, but also because it could potentially save you some cash as well.

Economy 7 isn’t always suitable for everyone and it works best if you’ve got things like Storage Heaters and/or you place at least two thirds of your electricity usage each day between the cheaper hours - usually between roughly midnight and 7am but the Support Team will be happy to confirm that and we can help with that on the forum too.

If you don’t meet the right sort of profile for Economy 7 or you don’t use it to the best of the capability, then E7 might not be right for you and you could end up paying more for your electricity than you should. The Support Team can help with calculating whether you’re better off switching back to Single-Rate or staying on Economy 7 and there’s no charge for asking for advice. If you do switch to Single-Rate, this is considered a change of contract and you might be charged a fee - you’ll always be informed upfront and you can always ask to leave things as they are instead.

If you do request to switch to Single-Rate, your Smart Meter can be updated remotely via SMETS Commands, so you won’t need to have it replaced or have an engineer visit to disable Economy 7 mode.

I hope this helps. If you need any more advice on what Economy 7 is or what it means, we’ve got some great guides on the Forum like this one.

But if you’re still confused, feel free to ask. :)

OK, so this is going to be a stupid question but I got  to ask it.

 

If there is no power (e.g. power cut) is the meter going to go dead too? I mean is there a back up battery or something like that?

I am asking because the guide above would suggest that there is?

“If your supply is off and you’re unsure if this a meter fault or power cut, the metrology light is a good indicator. If off supply and:

  • Metrology light is off - power is not entering the meter indicating a fault with the incoming supply. This means their may be a power cut or issue with DNO equipment, therefore the member should check with neighbours and potentially contact DNO.”

I had that very situation. No power in the house and Metrology light off. I had DNO engineer out and they told me that there is power in the meter. To cut a long story short, it turned out that the meter is set up, unknowing to me, as a pay as you go and there is no credit in the meter.

So, I guess the above guide, that suggests if no power in a house AND Metrology light is off indicates fault with the incoming supply is not correct?

Hey there @Zalek !

Thanks for the catch. I think the guide was written primarily with Pay Monthly/Credit customers in mind, rather than Pay As You Go/Prepayment customers, since the Boost Forum usually takes care of members on Boost PAYG. If you’ve run out of PAYG credit the meter should usually show you that on the display, but I can see where you’re coming from there. Nice catch!

I’ll go ahead and have a chat with @Tim_OVO about this, as it might be possible to update the guide to clarify things a bit better and hopefully reduce confusion. We’ll keep you posted with any updates.

Thanks for bringing this up! I hope you managed to get the lights back on.

Is this a new flat/house which you’ve just moved to, @Zalek ?

Or did this ‘fault’ suddenly occur without warning?

I’m puzzled that you had no relevant message on the meter itself or the IHD.

Userlevel 1

It’s all been quite a mess. Turns out the account we set up in August as DD has been cancelled (apparently something went wrong with “the system”) and it reverted back to how it was originally, which is Pay as you go. We had no idea until coming back home to find no power and no gas. All sorted now.

 

@Blastoise186 - yes, I can see that now. I assume if there is no power going to the meter (and, obviously, Metrology light is off) it’s probably the whole meter being dead (since there is no power). I think it would still be good to clarify that point, if anyone knows.

In that case, your wish is my command. The updates have been made, so hopefully that should be fixed now. If you ever spot any other mistakes on the forum guides, feel free to let us know in the relevant thread. We’ll make sure to get them fixed up!

Likewise, feel free to flag up any mistakes pretty much anywhere on OVO’s websites too. Whether you go via the forum or Support Team, it’ll be passed on to the right teams from there. :)
