Smart meter readings don't make sense, why is 1 month so different from the rest?

Hi,

The electricity readings on the OVO website have started to look funny. Here are July and August. July looks fine. August looks wrong. (Half of May and June is also wrong)

Any ideas?

 

Thanks.

 

Mike

Smart meters need to be set to daily or (better) half-hourly readings for you to have the most detailed Usage data on your online account and app. Our Support Team can change the reading schedule for you 😁. The online/app Usage pages will provide accurate data as long as your meter is sending reads. If any readings are missed, or if the meter stops sending reads altogether, then the Usage data won’t be accurate for that time.

 

 

Your meters can drop their connection now and then which is what appears to have happened to yours. That’s why some of us also use authorised third party apps which can sometimes help. 

It is your meter readings at the beginning and end of your billing cycle which determine your bill of course but the daily info can also be helpful. 
The Hugo feed in particular is very good at recovering missing data slots from the central data log (DCC). These are not accurate enough to add together for total usage (nor are OVO’s) but are good enough as an indication of usage

I can’t get daily readings from the OVO website.

...and, (I hadn’t noticed before) there are no meter readings for August, either Smart or Estimated.

It jumps straight from 31 July to 11 Sept.

Your earlier August graphics are estimated then. Does it begin to return to what you expect from mid September ?

Yes it does. There’s a funny period in June, which is the same, then it seems OK, then it fails again in August, and now it’s OK. Here are May - Sept (axes change obviously)

    OK, thanks. Is it safe to give your data to Hugo? Who are they?

      They are authorised to collect your data from the DCC (which is where OVO and all suppliers get their data from).

      https://hugoenergyapp.co.uk/

      They are one of a number of providers who also offer schemes similar to Power Move and switching services (less frequently at present). 
      I actually use Hugo, Loop, Bright and SmartThings as I like to research what is available. I also used ivie (available from Chameleon who manufacture IHD’s) previously

      @mboursnell ask ovo to check you are setup for 30min smart meter readings if you can't see any.

        @mboursnell are you making use of the the OVO Anytime tariff when charging your EV?

        They say we can’t have it because we have solar panels.
