Smart Economy 10 - Just had new meter installed is it too early to worry if the tariffs are the right way round?

We had a smart meter installed on Tuesday to replace the old THTC setup with Smart Economy 10. Everything has gone well so far - pleasant engineer, neat installation, heaters and hot water coming on at the right times, correct tariffs showing on the IHD at the correct times.

 

I've been waiting for the new meter to show on my account and today it popped up, though the old heating meter still shows as well, and both readings from the smart meter are currently being allocated to "anytime". I'm not too worried about that as I assume it will eventually sort itself out. 

 

What I'm wondering about is, on the meter itself TOU rate 1 is the peak rate and TOU rate 2 is the offpeak rate. But when I go to https://smartpaymapi.ovoenergy.com/orex/api/supply-points/account/<account number> I see that Tier 1 is labelled offpeak:

 

"region":"_P","profileClass":"01","meterType":"S2ADE","mapId":"UPLD","lineLossFactorClassId":"100","registers":[{"tier":1,"clockingTimeId":532,"timeOfUseLabel":"offpeak","meterRegisterId":"1","timePatternRegime":532,"measurementQuantityId":"AI","switchedLoadIndicator":null,"meterRegisterMultiplier":1,"registerMappingCoefficient":"1"},{"tier":2,"clockingTimeId":533,"timeOfUseLabel":"peak","meterRegisterId":"2","timePatternRegime":533,"measurementQuantityId":"AI","switchedLoadIndicator":null,"meterRegisterMultiplier":1,"registerMappingCoefficient":"1"}],"start":"2007-12-31T00:00:00.000Z","end":null,"fuel":"Electricity","meterNoOfDigitsOrDials":5},

 

The readings API shows the readings for Tier 1 and Tier 2 matching what I see on the smart meter display (ie Tier 1 matches TOU Rate 1 ie peak, as it's by far the lower value):

 

"readingDateTime":"2024-12-13T00:00:00","readingType":"SmartReading","fuel":"electricity","tiers":[{"meterRegisterReading":16.381,"registerTier":1},{"meterRegisterReading":145.138,"registerTier":2}]},

 

This looks to me like I'll be billed exactly the wrong way round, when billing catches up. Or am I reading this wrong? Should I be raising this with OVO already?

 

I should say, thanks very much to everyone who's been contributing to the THTC/smart meter threads over the past year or so for keeping lurkers like me up to date with progress and helping us understand the process better!

Since your meter is only a few days old, I shouldn’t take much notice of what you see in these various API results. It will take some time for everything to fall into place. In particular, the ‘supply points’ result is primarily for billing, not metering. It’s updated infrequently and it’s likely to change over the next few weeks, so you can’t take it (yet) as a true indication of your meter’s configuration. I’d point out, for example, that TPR 532 is half of SSC 510 (533 is the other half), and that SSC is supposedly only for PC 02 (multi-rate meters). So take it all with a large pinch of salt for the time being.

You showed us a bit of the API’s meter readings result. What do you see on the website’s readings history page? That should (eventually) indicate whether your readings are being recorded the right way round. Here are my latest ones:
  

Peak and offpeak clearly labelled

So, don’t start panicking yet - it’s still very early days.

TPR 532 has offpeak times 04:30-0730, 13:30-16:30 and 20:30-00:30 as you were expecting. We were once led to believe that DCC didn’t like getting offpeak register readings as Tier 1, but that restriction may have been removed. If your readings are showing the right way round (i.e. the reading labelled Peak is the one you see on your meter for peak-time usage), you seem to be good to go.

Please keep us posted how it all progresses!

The SMETS Command Update Tariff Configuration usually fixes that. But you’ll want to wait out the six weeks first and for the account itself to update to your new tariff. :)

We're now at 9 weeks exactly and the account has just updated to Economy 10 today. The old heating meter has disappeared from the account and the daily meter readings are applied to the right tariff - yay!

 

I'm still seeing the old meter on the API output (and the same codes against the smart meter which look to be older codes) but presumably that will catch up. Certainly the OVO account and billing look fine now. 

 

Thanks ​@Blastoise186 , ​@Firedog and ​@Emmanuelle_OVO  for your input. This looks to be an example of a successful migration from THTC on RTS to Economy 10 on a smart meter :)

Sweet! That’s REALLY, REALLY good to hear!

Yeah, everything sounds like it’s doing the number crunching correctly then. I suspect the old meter won’t totally disappear from the account for a while as IIRC the system tends to remember what meters you’ve had previously. But as long as future billing is being done against the active meter I’d say that’s the most important thing.

Oops, I slightly jumped the gun. When I took a closer look at the bills, they were charging the wrong tariff for the wrong unit (even though the smart meter readings are correctly assigned). I suppose the good news there is that when that gets sorted out the bills will be less!

 

I've spoken to Customer Services and apparently there's a hold on my billing at the moment because of the discrepancy and it will need manually sorted out. So, we're not quite there but hopefully getting closer.

 

Something to keep an eye on :)

Sounds like someone’s already on the case. They’ll let you know when they have updates

Hey ​​​​​@ClaireL 

This feedback is super helpful to customers in a similar position thank you so much for the update. Seems mostly positive & I hope all is well once the billing hold is removed. 😊

I thought I'd give a final update on this thread, now that it's been sorted.

The billing discrepancy that had been noticed by OVO (which was why the billing was on hold) was a historical issue from a couple of years ago which I think affected a lot of people? We received a letter saying we owed something but that due to back billing rules we weren't being charged. At that point the billing was taken off hold and the bills continued to be wrong.

It's taken several chats, phone calls and emails, and unfortunately in the end a few emails to the Complaints address as we weren't getting any response or follow up as promised, but someone called Nathan phoned today to say he'd sorted the problem and the bills now look a lot better! 

So in this case, the smart meter has been doing the right thing all along and correctly tagging the 2 readings right from the start, which is great, and they are showing the right way round on the meter readings page. Unfortunately the billing system was then misattributing these readings to the wrong rates. 

Ah well, it's all sorted now. Just in time for us to get a heat pump installed in a couple of months' time and then I'll need to see if we can move tariffs to a single rate one...  😊

Morning ​@ClaireL,

 

Absolutely brilliant news that this is finally sorted - I’ve read back through this and it sounds like a really frustrating time indeed 😣. Keep an eye on the bills going forward just to be sure, but from what you’ve said it sounds like this is all going as it should do now.

 

On the subject of changing to a single rate tariff - this is easily done. You’ll just need to ask our Support Team to give you a quote for what we have available. In the office we’d call this a ‘P2 to P1’ plan - basically, we still take two reads from your meter, but we bill both sets of reads on the same single unit rate. This is something that needs to be put in place by the Support Team then, once it’s in place, you’ll be quoted single rate plans in future when your plan is up for renewal etc. Our Support Team will also be able to assess your peak / off-peak split to see whether a single rate plan is definitely the best option.

 

Let us know when you get your heat pump installed and we’ll add the relevant badge to your Forum account, so that other Forum members will be able to recognise you’ve got one. There’s also heaps of great information about heat pumps on the Forum:

 

 

Have a great weekend!

@ClaireL Great to see it all worked in the end. Thanks so much for keeping us updated.

  ​​​​​​​

One teeny little caveat here: unless something has changed recently, the change from dual-rate to single is irreversible - there’s no going back. Don’t ask why! Of course, when your heat pump’s up and running, you probably wouldn’t ever need to do that. I’m only putting this here just in case someone falls over Ben’s instructions in the future unaware of the potential pitfall.

Yes you are right ​@Firedog! Definitely worth pointing out. Of course, if anything changes in that regard we’ll update all relevant forum topics.
