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

Any discrepancies like this must be reported to our Support Team.

Thank you for that detailed reply…..appreciated!

I took the time to write down the various tariff rate and time changes from my IHD, and according to that everything is reversed. I am supposedly getting 14 off peak and 10 peak hours….so in effect Economy 14. Thats okay in summer perhaps but when the night storage heaters start being used I want to make sure they get charged up at off peak rates!

I need to know if my meter is out of sync with the offpeak circuits in my flat, or if its just a corruption of my IHD data

Unfortunately, whilst meter readings are showing on my online account, usage and billing are not being updated. The meter readings do look a bit ‘peak heavy’ but at the moment Im trusting to luck and I dont like it

Before you say ‘contact support’ I tried the link and what transpired got me to screaming point. Three times I opened a session, answered security and some dumb standard questions from the bot, then sat like a lemon for around 45 mins waiting for a service agent to connect. Apparently I was always number 1 in the queue so I guess I was reallllll unlucky haha

I know I havent got the technical knowledge, but i do work with numbers for a living, so I know something isnt right…..I just dont know if its serious or not

Can anyone offer a way of getting someone technical on the phone who can send check my setup and perhaps send a remote reset command or suchlike?

 

Many Thanks in advance

There is no remote reset of that kind. The best option is https://smart-meter-help.ovoenergy.com and then leave it with the team.

I need to know if my meter is out of sync with the offpeak circuits in my flat,

… meter readings are showing on my online account,

 

This sounds as if your account is now on OVO’s latest billing system. Does your Readings history page look like this?
  

   

If so, you may be able to see the way your meter is set up to record usage on the various registers. If what follows becomes too technical, please forgive me and ignore it 🙂

 

First, get hold of your meter configuration details: while signed in to your account (e.g while viewing that readings page), open a new tab in the same browser session and visit this page: 
smartpaymapi.ovoenergy.com/orex/api/supply-points/account/1234567 
substituting your own account number for the last seven characters in that URL. 

This should show you a page with JSON data about your meter. It may be an impenetrable mess, or if you’re lucky it may be quite legible - it depends on your browser’s capabilities. This is what my E7 configuration looks like:
  

Supply Point data, topped and tailed

Each meter register is called a “tier”, each with its own number,  “timeOfUseLabel” (TOU) and  “timePatternRegime” (TPR). Make a note of these details.

Then download and open this PDF: TPR_Reference_sheet_2022.pdf (engie.co.uk) to enable you to decode the TPRs. The table is arranged for the convenience of electricity distributors, not consumers, so the second column with TPRs is sadly not in numerical order. That’s why you have to use Search to find the ones you’re looking for. Each one has five digits, so you have to add leading zeroes to make up the numbers. Mine are thus 00040 and 00206, and this is what I learn from the table:

Tier TOU TPR Timings
1 Peak 00040 Weekdays & Weekends 0700-2400
2 Offpeak 00206 All days 0000-0700

 

The times are in UTC, so there may be an hour’s difference during BST.

I’d be very interested to see what your E10 setup looks like if you made it this far. Does it seem to match your expectations, even though the IHD may have different ideas?

Well I managed to get the data (see below). Found the TPR codes on that PDF and allowing for BST the times do match my expectations, however they are the complete reverse of what shows on my IHD

For instance TPR 374 gives off peak at 00:00 to 05:00 yet when I check my IHD at say 3am, I see a red light on the IHD and hourly usage shows at around £1.35. With SEB it was always around 85p

Not sure if its just my IHD has corrupted, or its someone with fat fingers at Ovo…..trouble is i have to wait 6 weeks for my usage and billing to update due to “verification”

Sincere thanks for getting involved…..youve certainly gone above and beyond 👍

As an example, as of right now at 10:35, my tariff shows at 25.96p with next change to 34.86p at 14:00

Even allowing for the 1 hour BST this should be peak rate ie the higher figure

When I switched  on my offpeak switch just now, the light doesnt come on. so my flat doesnt think it is in a cheap rate period

Good to hear the meter’s set up correctly, @MikeMilf. Top self serving workaround from our non-engineer engineer, Firedog. Mike I’d wait 6 weeks till your switch date and if the IHD is still showing those registers round the wrong way, ask for it to be repaired with our Support team. If that doesn’t work you’ve already raised the issue with the Smart team so you can sit back and wait for those 45 days. 

 

Nothing showing on the IHD affects your billing or charges.

Yup...I think I should get some perspective and just wait the six weeks, by which time I should have my first bill

Looking at the meter readings on the website, overall I think the daily readings are in range, whether they are chargd tt the correct rate just needs confirmation

Guess I should sign off for now and give you guys some peace! Will report back if anything of significance develops

Yes I know I said I would wait six weeks and I guess I have to, but this development has me a little concerned

For the last three days I have kept my off peak circuit for the immersion tank mainly switched off, purely to get some baseline readings so to speak. I then only turn it on at 2pm (I work from home) to take advantage of the cheap rate

What concerns me is that looking on my account, it is the peak rate readings that are spiking a bit not the off-peak which are staying pretty much static day to day

Every time I switch the immersion on, my IHD light goes immediately red (as I have previosly mentioned), which never happened with SEB.

Whilst I know you said the status/settings of my IHD wont affect my bill, but this doesnt seem to be born out by what Im seeing. I just dont fancy being overcharged and then trying to get a credit. My own experience is that easier to find rocking horse muck, than get accounts staff to understand technical matters

 

PS You guys have been brilliant, so no offence intended
