Help with OVO app Usage disparity of KWH figures

The Month view is populated with estimated figures. I expect the system is having trouble working out how much energy you’re consuming from the grid (which you have to pay for) and how much is coming from your PV array, compounded by having an HP tariff. Contact Support and ask for their help. It may be best to use webchat, where you’re able to upload screenshots illustrating the problem if they need them.

Is this behaviour the same now at the end of February? 

Have you had your January bill? Or seen it on the website? Does it look at all reasonable?

Hi ​@EricofNB and a warm welcome to the OVO Forum.

Thanks for your post. On top of ​@Firedog’s helpful reply I recommend that you check your readings for the same day to see exactly how many Kwh’s were used that day, you just need to calculate the difference between the two readings a day apart. This will then show whether it’s the daily or monthly usage that’s wrong. 

I could be incorrect here but, from looking at your screenshots, it looks like you may be using the web browser online account on a tablet / mobile? I’d recommend downloading the OVO App, as this should give you better compatibility with your device. It would also be useful to know if the same issue is present in the App. If you could let us know that would be great!

Please note - we’re in the process of updating these topics with new info and screenshots - you may find that some of the screenshots don’t exactly match what you can see on your own app.

Hi Ben,

Thanks for your ideas. I have compared every day from 1st jan to this week and it is the daily figure that is correct, it corresponds very closely to our Solax figure and our Smart display. The disparity comes with the Month view. It is as if they lose 75% of my kwh, or they have a maximum daily limit of 14kwh. 

By the way I do normally use the app but I tried the web browser just to eliminate an error on the app- Both the same however.

So here is a screenshot of a week in Jan. Cost is in pounds. OVO consumption is from the “Monthly” usage page downloaded to individual days. OVO Daily is from “Daily” usage page, they just bare no resemblance to one another. The final column is heat pump usage.

Hi Firedog, Thanks for your help. I don't think the solar is having an effect yet. In January we barely get any sun. This seems more of a software calculation issue. I was just looking to see if others have a similar issue. I suspect it is the Heat Pump Tariff, somehow they are mixing up the Vaillant data. But no amount of fiddling seems to match the numbers up.

Let’s not forget that the HP plan is a rebate for each kWh used by the pump. If billing is calculating the rebate on the basis of those ~13kWh figures, ​@EricofNB is going to be seriously out of pocket. It’s not just a cosmetic issue on the Usage pages.
