Random smart meter readings caused billing issue?

Hi 

I enter my readings monthly both gas and electricity manually. For some reason yesterday I had a smart reading applied to my monthly readings which is over 14000, whereas the actual reading on the meter is approx 11560. This has clearly provided incorrect billing details as I’m sure you can imagine and from a monthly use off approx 100 this month it’s shot up by 3000. A false reading. A clear error. 
 

from what I am aware I don’t even have a smart meter and have manually inputted readings for over 3 years now. 
 

I have checked online and it states my meter isn’t working on smart mode which again begs the question where this incorrect reading has came from 
 

having called OVO , no one could explain and the person said ‘the meter must have had some sort of fit’ how that’s a suitable response is beyond me. they adjusted the reading to the correct one but again a 14000 odd reading is now evident again today from ‘another smart reading’ so basically it was a waste of time. 
 

it’s soul destroying having to waste time proving readings whereas this is an issue with OVO. I guess back on the call tomorrow. 
 

has anyone had issues like this previously? 
 

really disappointing

Folks,

engineer attended yesterday for a site investigation. 
confimed the recorded readings at OVO were well off , as per my understanding of it prior to his visit, he said he had not seen anything like this previously. Readings were over 3000 out. 
 

the old meter was removed and replaced with a new smart meter. The old reading of 11625 was recorded on his system and on a sticker  next to the new meter. 
 

he said the old one was decommissioned and the new one would be registered to me on the DCC. 
 

to this point today, I have had no random smart readings lodged against my account 

 

hopefully the correct final reading of 11625 will be used by OVO  against the new meter starting at 00000 and not the incorrect 14000 odd readings , but we shall see what happens I guess as I’ve lost confidence in this whole situation, just hope it doesn’t get worse introducing a new  meter but shall see

I meant actually talking to someone rather than trying automated systems.

TBH I would just do it once a month on the 15th which is your billing period start.

I know how frustrating it gets explaining the same thing to different people so why do that daily?

Personally I'd give it a couple of weeks after reporting something like this to give someone a chance to look and find/fix the issue - then if nothing has changed make an offical complaint.

As you say these phantom readings are not appearing on the ‘live billing’ then they shouldn't appear on your monthly bill either - especially if you phone in an actual reading on the 15th.

… please see below photo from last night , 
  

Interesting. That is indeed a smart meter, an L&G type ZCXS310H2.1. This SMETS1 meter needs an external communications hub in order to be able to transmit data over the smart meter network, so it should be somewhere close by.  Perhaps you could upload a photo of the comms hub as well.

You’re quite sure that the serial number Z18N246094 is the one printed on your bills and shown on the Meters page on the app?

There appears to be a distinct crossed wire here somewhere.

@Firedog are you thinking SMETS1 that has just joined DCC?

I thought that wasn't ongoing anymore but don't see why it couldn't be possible.

I shouldn’t be surprised if enrolment and adoption on to DCC played a part here. It was declared years ago that they wouldn’t bother trying to migrate L&G meters connected by Trilliant comms hubs. But even though they (DCC) had tried again to adopt this meter and succeeded, I’d expect usage data and index readings retrieved to reflect what the customer can see on the meter’s display, so long as the MSN matches, of course.

Hey ​@callumrust 

 

Sorry to hear this.

 

You do have a smart meter, does the serial number on the bills match the one on the meter?

 

It’s definitely odd, do you have another register on the meter? If you press that button again do you get a different reading or is it just the one number?

I thought that wasn't ongoing anymore but don't see why it couldn't be possible.

I know the DCC are still working with suppliers to get any remaining 1st generation meters enrolled directly, but I’d imagine there to be a note on the account that explained this so any agent would be able to see if that had occurred recently or not.

Hi Abby the series meter on the bill matches the meter yes. Even if it is a smart meter and is somehow correcting with OVO after 3 years of not , the readings are way way off

I’ve noticed over the weekend there looks to be a trilliant attachment onto the meter in the cupboard. I’ve noticed the WAN light is not on at all, the HAN is blinking red and the power is green. 
 

would that shed any light on the issue?

Looking into it online it would suggest the meter isn’t sending a reading to OVO. So although perhaps not working, for whatever reason, doesn’t explain the incorrect meter readings being supplied to OVO from ‘a smart meter’ being billed against my account 

 

when I moved into the property circa 3 years ago, there was no IHD present for info

Thanks for that info.

I'd though they had now got to the stage of diminishing returns, ie.

“not happening with the few that are now left unadopted so it's going to be easier to exchange them for new SMETS2 meters”.

If they are not quite there yet then it can't be far off.

Hey ​@callumrust 

 

No it definitely still doesn’t explain why it’s changed over all of a sudden. I’m going to flag to some teams and see if we can get any further advice here.

 

@Nukecad there’s a little more about it on the DDC website but they don’t say how many are left. I’d believe it’s mostly the one’s they struggled updating and that’s why they’re having to work so closely with suppliers to get the last completed.
