Switched supplier: Economy 7 smart meter not sending reads and IHD needs re-configuring?

Hopefully theres nothing to be concerned about but…..

Had a SMETS2 meter for about 9 months with SEB and its always worked fine, as has the IHD. Have recently been switched to OVO and suddenly Im being told my account is not getting readings

Is there a usual ‘bedding in time’ so to speak? Lights on the meter are all flashing green every 5 seconds, and the IHD usage reading are updating as normal

Yes I can supply manual readings I guess, but it rather defeats the point

 

Hopefully Im jumping the gun and it will sort itself out, but thought it best to ask

TIA

Posting here as I started a similar thread and @Firedog linked me to this.

Looking at the above and talking to OVO, I think I understand the cause of the problem and also have a possible solution albeit not an instant one, having spoken with OVO CS

The coding for the meter is switching the tariffs correctly, but the tariff number is wrong.  Tarif 1 has been linked to off peak and tariff 2 has been linked to peak.  I have just had a long but useful call with OVO CS and they have agreed this is the likely issue.  I have been asked to conduct a load test and note which tariffs change and by how much during each on / off peak section of the next day and call back with the results.

Having done that for this afternoons off peak, whilst using my hot water (draws only from the off peak circuit), the immersion heater is working and switched on at the correct time (1pm) but it is being attributed to tariff 1 for cost (peak rate) as that has gone up on the. meter and tariff 2 has not moved at all despite me using an immersion heater for nearly 4 hours now.

If you’re having this issue, it isn't going to resolve over time (unless OVO realise the mistake and update all the affected meters) so please call the CS and tell them so they can resolve the issue.  If you do your load tests in advance, note times and readings for each tariff at the start end end of each switch time, directly from the meter (not the IHD) and the tariff rate displayed on the meter at the time.

I don't think it will be. quick fix, the response form CS was once the issue is confirmed with these readings, it's an engineer visit after that but this should get the ball rolling to get the issue highlighted to OVO and corrected.

 

Hope this is of some use and helps to get this resolved for us all

Hi @MikeMilf , yes, with any switch, the meters take a while to get back in sync. If they behaved previously they should be ok. Worth keeping an eye on them and a manual reading in the meantime helps smooth your usage level

Thank you for a swift reply

I did think that would be the case as everything appears to be working but thought it best to ask

Will keep an eye on things as you say!

keep an eye on it!  I was with Shell moved on the 13th April, still can’t see any data 4 months later, apart from 2 days in May when it worked!!!!  I can see my data in Loop so obviously an issue between OVO and the DCC not my meter.  Somewhat fed up now!

Hmmm that doesnt sound encouraging. What is it like dealing with Ovo customer services? I was with SEB for many years and towards the end (post Ovo merger) their support and website was utterly appalling

I got a smart meter around a year ago, and never did get my data linked to my website account. On the other hand it linked to the phone app inside a week…..go figure lol

Speaking of which, the Ovo website now says it is receiving data so I will check for readings and ongoing bill over the weekend. Fingers crossed.

bit rubbish, I have had 3 web chats and the issue is still ongoing. I can see the data in loop but its still annoying and I have to give manual meter readings.  Also my opening meter reading was messed up so my billing has been a shambles!

Yup….we now have 4 days of smart meter readings shown on my account, but my actual usage/billing isnt updating. Will give it another seven days

On a separate note (and forum discussion) my smart meter/IHD seems to have gone out of sync with my off peak circuits in my home. According to the tariff times shown my IHD, 2am (dont ask) is peak rate and only switches to off peak at 6am

This presumably means that whenever my off peak circuits switch on at midnight, I am going to get charged full rate. Yes I did check that all the switches in my immersion cupboad were as they should be. I only noticed there was an issue as my IHD was showing a red usage light…..something that has never happened previously since having it installed

Your IHD isn’t the ‘rule’ for peak and off-peak timing. As you suggest, it’s probably just out of sync. It might need a command to put it back from the support team.

Aye I know you are right…..

Something has definitely changed though as I checked my tariff on the IHD in Early July to make sure SEB had reduced prices following the price cap change

Is there a way of contacting support directly without  going through customer services?

That’s not likely. If the meter has been properly configured, it will clock all usage on the appropriate register according to the time configuration. This is regardless of any switching of circuits that might take place. So even though the IHD shows something different, usage in the specified off-peak period will be charged at the off-peak rate.

When your online account settles down, you’ll see that there’s not a precise relationship between half-hourly and daily usage figures. That’s because the daily figures are taken from the meter readings themselves, but half-hourly usage is taken from the consumption figures that DCC provides.

Your bills are always calculated from the meter readings. You’ll see the peak and off-peak figures on the Readings page, so you can check whether there’s any great difference between the aggregate half-hourly usage in the off-peak period and the difference between the meter readings for the same register on the same day. It should be quite obvious if two hours of immersion heater usage (perhaps 6kWh) are wrongly recorded on the peak register.
