Hi @natmorrison1989 This is quite normal.

If it’s a second generation smart meter, the explanation below (taken from another topic I've written here) outlines why:

After three days (from the installation), my In-Home Display (IHD) suddenly started displaying real data
 

... but the figures bore little resemblance to the actual energy used.

This is all quite normal. There is a lot of work which continues in the background once the on-site installation is complete.

Not only will DCC be testing and tuning the encrypted communication links, but OVO will be installing your actual tariff data. This is held in the master electricity meter and is only required for you to view readings on the IHD. The actual usage figures are calculated separately by OVO as part of their billing process.

It can take several weeks before the entire process is completed. Only then will your IHD reflect the same information visible on your online account or OVO app (download for Android or iOS).

If there are any discrepancies in billed usage in the meantime, these will get automatically corrected because the actual meter readings are cumulative.

@Franster

I'm assuming you mean that the IHD is showing huge usage and costs. The meter itself has no costs displayed.

I think we can fairly certain that OVO are busy looking for a fix... as, presumably, are the other Energy Suppliers who have recently installed the Chameleon IHDs.

However, we don't yet know if the bug affects all Chameleons, or whether OVO are expecting customers to contact them if theirs is one that manifests the fault. So I suggest you email the team, and alert Customer Services that yours is a site with this problem.

It does seem odd to me that we haven't received emails alerting us to the fault.

I don’t know if this is a general problem with last night’s processing, or just a problem with my account; but I noticed that yesterday’s billed units are significantly higher than actual usage.

Is anyone else having the same problem?

Hi @MCH59 , you usage for 17th would be taken from the readings for 17th and 18th - the meter is read just after midnight usually. It may be that the reading for 18th has been estimated. 
The other thing to remember is that it’s the meter readings which form the bill, not the graph - that’s just for indication. 

No, the readings dated 17th on the first image are definitely the ones from midnight 17/18th July … and the IHD, ivie, Hugo and Loop all agree that I used fewer kWh yesterday (17th) than on any other day so far in July. 

Ignore the £ in the image below because my meters and IHD are still showing the old tariffs. 

Forget it … I just looked again and both the cost to date and kWh have sorted themselves out.  How weird.

Thanks anyway.

So far I've been quite pleased with the service from OVO.
Today I'm a bit perplexed! I was issued an IHD3 a couple of months ago. The total gas and electricity daily costs which I recorded always matched  when totalled with the monthly costs.
But having recorded the figures for the last week with the IHD3 when I checked the last week's figures again today (26/9/23) on the IHD3 they have changed!
As a sample: Sep 21 £2.46 is now showing 2.81, Sep22 £3.05 is now £2.87, Sep 23 £2.84 is now 2.77 Sep 24 £2.63 is now 2.70.
Grateful for any explanation. Thanks,
Paul F.

Hey @Paul Fonseka 

Sorry to hear about the trouble with the IHD.

We don’t have access to accounts here at the Forum so we aren’t able to tell exactly what the problem might be. You’ll be best to contact the Support Team who’ll be able to run some checks and make sure the details on the account match up to what’s showing on the IHD

I’ve linked to a really helpful guide on IHDs that might be useful for you, it includes details on the IHD3 so it might be worth checking that out before contacting the Support Team;

Ok, thanks Abby.
