They are set automatically but sometimes get ‘stuck’. Here’s a similar thread 

OK, this is weird. The tariff on my IHD is higher on the IHD than the app, but the overall usage is showing lower on the IHD than the app. 

In that case, I would check the actual meter readings on your account page to see if how that tallys.

https://account.ovoenergy.com/meter-readings

There is standing charge and vat to account for as well

OK, that explains it. “Your electricity smart meter hasn't sent us any readings lately. To keep your account up to date, you'll need to send us regular manual readings”. For some reason, the smart meter has gone offline. Great 

Thanks for your help in my understanding of this.

I do check mine every so often so that I don’t get estimates. If it’s been out of sync for a while, you should be able to send a manual reading but if it stays ‘off-line’ then it’s worth reaching out to OVO to sort

Yes, I’ve just sent a manual reading. I also re-submitted the request to send data every half hour - maybe that will re-trigger the connection.

Overall, the smart meters are not exactly smart. This is our fourth meter.

Anyway, thanks again for your help.

Hey @Chris Brummell,

If your smart meter’s lose communication with us please complete a smart meter health check:

My account is showing that I've used more gas in two weeks I've been away than when I'm at home. The flat is empty so nobody using the hob and I turned off the boiler completely so no usage there. Nothing else uses gas!  Any ideas?

See if there are any non smart meter readings in that period 

https://account.ovoenergy.com/meter-readings/history/gas

I am just trying find out why my gas usage has spiked so suddenly.

My use of gas for hot water and cooking has changed very little and was showing as 2.30 kWh of gas used on 8th November.

However, the next day this has shot up to 47.91 kWh and has been at that level ever since.

Although I have a combi gas boiler, I have not been using the central heating and the radiators are turned off as I have been using low energy electric heaters.

I have also been using an air fryer and microwave instead of the gas oven for cooking but the gas use is still showing at these levels.

Any ideas?

Where are you seeing that usage @DJH1971 ? If in your account, have you checked to see if they’re using actual readings or estimated. Otherwise, you might want to check the meter and pipework - first take a few readings a number of hours (or a day) apart. If that’s still high, there might be a leak .. you could use the lever to switch the gas off if that’s possible (and needed)

On my Ovo energy account under ‘usage’.

I certainly don’t smell any gas either, as this would happen in a leak.

Just so baffled.

Yes but it should also say Smart, manual or estimated alongside the daily readings

It is saying Smart but it still doesn’t seem right. I haven't had the smart meter plugged in as not sure it was a smart meter (I took over from my late Dad who passed away in July) as we were on an energy supplier that went pop (not sure what they were) and we were switched to Ovo.

The last meter reading was on 4th November, which was before the spike.

That sounds very much as if the usage has been (over-)estimated in the absence of readings. You should be sure to take a manual reading on Friday morning 1 December (Thursday evening if that’s more convenient, but don’t submit it until Friday morning). That reading should be used to generate your November bill, negating all the spurious estimates. You can submit online on the app if you don’t see the option at the website.

The Usage charts are for convenience only; they have no bearing on how much you’re charged - that depends solely on meter readings.

The smart meter is the box on the wall near where the main electricity cable comes into the house. The little device you haven’t plugged in is the In-Home Display, which you might find helpful especially if the meter itself isn’t communicating data to OVO properly. Does it work if you plug it in to a socket as close to the meter as you can get, then leave it for a couple of hours to settle in? 

Hey @DJH1971,

Welcome to the OVO Online Community,

The first thing that occurs to me is that some of the readings might be estimated:

If the reads are all smart it may be that an appliance in the property, or your meter is faulty:

Hi @DJH1971 

Sorry to hear about your issues. I don't work for ovo, I am just a customer like you.

Some good advice above. See if this helps as well.

1. If you haven't already have a look at this page and make sure there is a daily reading with the word smart next to it for every day.

https://account.ovoenergy.com/meter-readings/history/gas

2. Can you take a picture of your smart meter and post it on the forum so we can see it

3. On the usage page do you see day month year tabs

4. If you look on the website not the app

https://account.ovoenergy.com/plan

You will see something called Future Annual Consumption. If you have a smart meter but it isn't communicating with ovo, then this will be used to estimate your consumption.

It appears that my smart meter is not communicating properly as all the lights such as 'WAN' are flashing and I have reported this to Ovo.

I submitted a manual reading on the Ovo website and that now seems to show pretty much what I actually used 

In case it helps

You can run this check to see if your meter is working in smart mode

https://smartmetercheck.citizensadvice.org.uk/

Ovo also have a tool they use to diagnose issues

https://smart-meter-help.ovoenergy.com/

On many types of communications hub (that’s the bit with the WAN, HAN etc. lights), they’re supposed to flash. The frequency of the flashes is in some cases a diagnostic tool. This is from a site I find very helpful:
  

So you’re all sorted now, with no more unexplained spikes?

Hi everyone 

Have any of you had any issues with your March bill?

My electricity charges are incorrect - they've used 1/3 meter readings as a start and 5/3 meter reading as an end despite having a daily reading for the entire month from my smart meter.

I've spoken to 4 different people on the help chat and was promised it would be sorted so I wouldn't have a massive catch up bill this month but no luck.

Also it keeps telling me it can't tell me if my direct debit is correct and this has been going on for a month now. Causing me major worry as money is tight enough without knowing where the heck we are with our account.

Any hints/suggestions or any similar stories please?

Thank you

Hey @Rheamean14, 

As this sounds like an account-specific issue, your best option to get this resolved is to speak directly with our Support Team. Sadly, we don’t have access to the account through the forum to help with this.

We do have a full billing guide that gives more information on how billing works that might help. 

I hope you get this resolved soon 

Thank you for the response.

Unfortunately I have done this 4 times and gotten nowhere.

At the end of my rope now to be honest. Causing a lot of stress 

Does the billing say it’s used actual readings or estimates?

Sometimes a Smart Meter reading doesn’t get to OVO for some reason.
Sometimes it might not be sending them, sometimes it is sending readings to the metering service, but they are not then getting passed on to OVO.
https://www.ovoenergy.com/help/article/what-to-do-if-your-smart-meter-isnt-sending-readings

Just a suggestion that may or may not work for you:

If your Smart Meter is currently sending daily readings then contact support and ask for that to be changed to half hourly readings - making that small change might just shake things up a bit, enough to put it back on track..

Hi thanks for the reply.

It's an actual reading from the electric meter. 

Spoken to them again this morning and apparently it's flagged on my account as an issue but the accounts team "have a backlog and rectifying the bill wasn't a priority". It's been escalated to high importance and the person I spoke to has also passed it to the complaints team.

Hopefully it will be sorted soon
