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.

Hi @vegas22 and thanks for this detailed breakdown of events. It’s really helpful to understand where you’re at. 

 

Whilst you wait for the July meter exchange, let’s see if the forum can help you figure out the readings on the meter vs the online account. Of course these should be aligned.

 

I think you have a first generation ‘Secure Liberty’ smart meter. Can you confirm by looking at this guide:

 

 

From that guide you’ll also see how to read the meter. Pressing 9 gives you the rate 1 meter reading. If your smart meter is for any reason set up in economy 7 setting, your readings will be on two registers which you can find by pressing 6. 

 

Can you confirm your latest meter readings showing on the online account and on the meter please?

Yes @vegas22 you need to make sure that you don’t confuse the various registers on your smartmeter. Tim has given you access to the guide and the main keys to use. 
This might also help as a quick guide depending on your exact meter type

Hi, thanks for your help.

It's a liberty 100.

If I press 9 I get

IMP KWH = 32916.1

If I press 6 I get:

TARRIF

ACT RATE

IMP R01

STCGH/DAY

050-300P

+IMP R01+

30165.8

032-390P

IMP RO2 (no + but I think I've seen it have a + at each end before)

2750.4

000-00P

IMP R03

000000

000-000P

after that it's all 0’s as it loops through R03-R15.

Below is screenshot from my OVO account with today's 20th smart reading:

 

Thanks in advance for your help.

@Tim_OVO@BPLightlog , It looks like my 9 reading (32916.1) is the same as RO1+RO2 (30165.8+2750.4). It also looks like my smart reading matches the R01.

9 brings up the ‘total’ register for the meter rather than the active one

Thank you for you help. So what does that mean? Sorry for all the questions.

As in the list I posted earlier, that gives the total reading since the meter was active (either imported or exported). 
The active register is normally seen as ACT 01 or ACT 02 depending on if you have a dual rate supply (peak and off peak). 
In everyday use, it’s ACT 01 reached via button 6 which gives the reading you need so in your review, it would be 30165 which you would log. As you had calculated, button 9 gives you both registers added together

@BPLightlog  Thank you for your help with this. So basically OVO telling me to use button 9 is what is causing the confusion.

I'm not on an economy 7 or any feed in TARRIF etc which makes the imp R02 confusing. Any idea why I even have numbers under that one?

Those figures are a lifetime register @vegas22 so it will have been recording in that mode at some point since it was fitted

I discovered exactly the same thing. My smart meter was installed by OVO when the property was on a night/day tariff. Once it was up and running I asked to be switched to a single rate tariff, hence that second register had been used a bit. Now it’s only the first register that records anything.
