How can I change the reading frequency of my smart meters? I have half hourly for gas and daily for electricity...

I have had a smart meter for several years and find the on line graphs very useful. Curiously, I can view hourly readings for gas but only daily for electricity. How can I change the electricity readings to hourly - or half hourly?

Great to hear you’re loving the online usage pages that use smart meter data to show what your using throughout the day.

 

As you’ve noticed we’re not currently getting half-hourly data from your electricity meter. You can change the reading schedule of your smart meter via your online account or app by following this guide:

 

 

 If you’re unable to do this please contact our Support Team, who can request a change to your meter reading schedule for you.

 

It’s worth remembering you’ll also be able to check usage info using your In-Home Display. Hope this helps get you full access to all the benefits of going Smart!

That’s fine @oldterry2 - the email will be in the “ToDo Queue” awaiting attention by the SMETS Team.

However, they’ve not currently got access to their lab at OVO’s HQ due to the pandemic crisis, so they’re “working from home”.

You’ve done exactly the right thing by posting here. I too would now like to learn what happens if a Smart Meter is only read once per month. I wonder whether they retrieve only the cumulative total since the last successful read. Or possibly they might get 1440 half-hourly readings which have been awaiting collection.

An update. 

As well as posting here, I also replied to the e-mail from hello asking if there was any progress. 

On the afternoon of the 16th, I got an email saying my readings were now being sent every half hour, and that would appear online after a few day.

I can now report that the electricity is being read every half hour (according to the usage page), while the gas is being read daily (rather than every half hour),  but that is frequent enough for my billing.

Thanks to everyone who helped.  Terry

Good to hear this, @oldterry2. There is an option to read the meter daily rather than half hourly, so there’s a possibility that it’s been changed to this. It might be worth sending the team an email to double check.

 

Cheers!

  I reported this to hello, they said that the gas had been set to half hour readings on the 15th.   So presumably either the note is wrong, or the mechanism for setting the reading rate  is erratic.

Keep a watch on this over the next few days @oldterry2 and see if anything changes.

Just so this is clear… even if the granularity of meter readings is half-hourly, they are still only picked up once per day, just after midnight. We don’t want someone else reading this Topic to be asking OVO for their meter to be read every 30 minutes. It doesn’t work like that (yet)!

 Well just to keep you informed.  There has been no further change - the gas is still on daily readings, and the records show it was changed (supposedly) to half hour ones.

Thanks for the update @oldterry2 

I reported my own lack of Usage Data last Friday (24apr) and provided the link to the screenshot I posted over here.

Today I received an email reply from Customer Services stating that they’d looked at the Forum Topic and didn’t understand the problem.

I’ve replied to that email, included a number of screenshots and clarified that there is a wider issue of customers having Smart Meter data missing.

I have specifically asked

  • that my email is forwarded to the programming team (in London)
  • that they don’t just fix my little problem and think they’ve solved it!

@Tim_OVO is aware of the extent of what us customers are reporting, and I have no doubt he’ll be adding his weight behind the scenes.

 

May I just clarify, in your case Terry,

I assume you’re seeing a daily histogram like this…?

What happens when you click on one of those blue vertical bars?

  • Anything at all?
  • Error message?
  • Blank screen?

Thanks.

 On the  daily usage bars  if I click a bar I get the date plus the use (Kwh ) and cost.

 On the electricity half hour bars I get the time plus use (kWh).

 does that help?

Erm… @oldterry2 - so you can click on the electricity half-hour bars. Correct?

Are you saying that you get that histogram on electricity, but not on gas?

But OVO send a single overnight command, and pick up all the readings from gas and electricity in one go.

So the issue isn’t that the half-hour readings aren’t being collected, but rather that the online Usage Histogram doesn’t allow you to see them. Is that right?

 

Going back to your electricity graphs for a moment….

When you hover the pointer over the bar, you should see the time and the kWh.

But I was asking what happens if you click on the bar. That should change from a histogram to show a line graph. Is this what you see?

 

If you are indeed seeing the two different types of graph (as above) for electricity, what do you see for gas?
