Smart meter manual reading different to smart reading

I’m hoping anyone on here can shed some light on this.

Before I go into the issue in more detail, my questions is as follows:

What can cause a manual reading on an ovo smart meter (when you press number 9) to be different to the smart readings ovo are receiving? 

*edited by moderator*

Hopefully I will get  a response from someone who knows about the meters.

In the mean time, if you have any idea why the meter is different please let me know below. I’ve researched online for hours but not been able to find anything.

At some stage, some consumption (2750.4 kWh) was recorded on Register 02. You’d have to go back through all the available meter readings (400 days worth) to see whether you can spot when that stopped happening. The other figures you see are

Standing Charge 50.300 p/day
R01 rate 32.390 p/kWh
R02 rate 0.000  p/kWh

 

So, this meter appears to have been set up for E7 but later reconfigured for single rate by simply diverting all usage to the one register. R01 is usually ‘Peak’ rate, but not necessarily. Incidentally, your rates are identical to mine.

 

The R02 register is showing an historical figure dating back to when the meter was configured for E7, and current usage is only recorded on R01. It’s odd, but that’s why the readings you see online are different from your Button 9 reading, which includes the obsolete figure from R02. Your current billing will be accurate. 

 

You will most probably have been charged for the 2750.4kWh a long time ago, so you’d have to check your old bills to see that. If you can’t see any appropriate charge, that usage is most likely to have taken place more than a year ago, in which case its cost will be written off. So I think you’re safe from any unexpected bill regardless of what happens when the meter is exchanged.

 

In my amateur opinion, the meter is working as expected and recording consumption as it’s been configured to. The problem seems only to be the intermittent transmission of data to OVO. Has the meter been enrolled and adopted (‘E&A’) on to the DCC system?  To check, enter its MPAN into this tool: smartmetercheck.citizensadvice.org.uk Because meters on DCC use a different way of communicating with the outside world, it could well be that the problem would change at E&A, with no way of knowing whether it would get better or worse.

 

If you can access your account on a computer, I’d be happy to help you do a little forensic analysis to try and find out where the R02 reading came from.

Great detective work everyone! 🕵🕵🏽🕵

 

I must say I didn’t know rate 1’s can be used in this way for former 2-rate set ups. Tis good to know!

 

So whenever your meter is out of communication and you want to submit an actual meter reading, @vegas22, press number 6 on that keypad!

Hello @Firedog @Tim_OVO @BPLightlog , thank you all for your help. Much more support on here than the ovo phones etc.

@Firedog I have access to my account but not sure what I would need to look out for regarding past bills. @Tim_OVO is there any way to pull bills from further back in my account e.g. several years?

 This is the screenshot of my meter readings back to 3 May 2022. I can’t really see any large jumps in readings so I suspect the 2750.4 kWh was before this time frame

** for some reason the forum wont let me upload the web capture**

looks like the screenshot is too large dimension wise.

ok, so I thought I’d worked out looking at my ovo > usage when i switched to a smart meter (march 2018) since the graph goes from showing the same value each day to fluctuating. 

 

However, when I look at my bills from Dec 2018 to march 2018, they all show the same Meter Serial Number (MSN) for electric.

I have to go all the way back to 25 Nov – 22 Dec 2016’s bill to find a different electric MSN

It also means that I’ve been contacting Ovo for 7 years to try and get to the bottom of this if that’s correct! (how time fly's when your having fun!)

Just thought I’d explain why your image couldn’t upload. For technical reasons, massive images like that one have to be rejected by the forum software because they break stuff. Nothing against you though.

Hey @vegas22,

 

Welcome to the OVO Online Community,

 

This is an interesting one! Sounds like your old usage graphs may no longer be accurate. What do your historic bills show? Do the ones prior to the smart meter exchange show the old meter serial number? If so, you’ve been billed correctly and you don’t need to worry.

There should be a yellow sticker on the meter which confirms the date of the meter exchange, @vegas22…

 

The usage section bars always showing the same usage does indeed indicate a non-smart meter, or a smart meter that isn’t sending its readings remotely. 

 

Either way just make sure you submit the correct reading via keypad number 6 and you won’t be incorrectly charged. Likewise if that meter ever gets replaced, you will be correctly billed throughout.

This is the sort of stuff that gets my adrenaline flowing! I just had a look at the elephantine screenshot you uploaded here: ovoenergy.jpg (1685×19083) (ourmessagebox.com). With @Jeffus’ acute observation that the DCC doesn’t usually produce daily readings on the first day of each quarter, I looked through your readings - and they’re all there. This suggests that the meter wasn’t on the DCC at the time, so it’s quite possible that it’s currently going through the throes of E&A. We may be able to spot this with a little bit of magic …

@vegas22 Let’s have a look at your readings database, the one that lies behind that long screenshot. Step by step:

  1. Sign in to account.ovoenergy.com. 
     
  2. In a new tab in the same browser session, open this page:
    smartpaymapi.ovoenergy.com/orex/api/meter-readings/{Account}
    where {Account} is your 7-digit OVO account no.
    Depending on which browser you’re using, this should reveal either a nicely readable JSON tree or an impenetrable block of data. 
     
  3. If it’s legible, go to step 5ff.
     
  4. If it’s not legible, copy the whole page (Ctrl-A-C) and paste it into the box on this page: https://jsonformatter.org/json-pretty-print, then click the Make Pretty button. You can copy the results in the lower pane ready to paste into Notepad or your favourite text editor.
     
  5. Scroll down to the data for 2023-05-29, then scroll gently up looking at the readingType. There will probably be some gaps corresponding to the dates omitted in your screenshot, but you should be able to see the anomalous one at 31 May.  Do you see any other odd ones then or later (higher up)?

    This page should show the meter readings for the past 400 days. Do you see more than one tier, or any mention of the 2750.4 figure seen on the meter? Is the registerTier numbering the same all the way to now? 


There may be other interesting things on that page.

@Firedogthank you for this, I didn't know you could pull that data (time to code a php script to log all this!)

 

I'm not at my computer at the moment but I'll do that and update you accordingly.

 

Regarding the meter itself, had a helpful chap come out and replace the meter. Explained the situation to him and he took the final reading using the number 6 on they keypad (which should stop ovo from incorrectly sending any strange bills).

 

However, whilst he did fit a larger t2 aerial, it didn't get any signal and as such he could not commission the unit. I've since unscrewed the aerial from the board and moved it to the window for now (looks horrible but the WAN light is now flashing so seems to be a temp fix).

 

I did ask if the T2 was waterproof but he said it wasn't and didn't know of a waterproof version. Does anyone know if there is one that ovo supply? If so, I could drill through my wall and mount one on the outside which would seem to fix this issue once and for all.

 

Also side note, my little colour smart meter display doesn't seem to be syncing with the meter (shows what looks like dummy data shipped with the device for demo purposes).

Any ideas how to get this working.
