Economy 7 tariff changes on SMETS2 meter but fifth terminal not activating at all!

You might want to delete your location and meter information in the previous data post @pegem 

Brilliant, thanks. Here’s your problem, I think:
  

[{"tier":1,"clockingTimeId":374,"timeOfUseLabel":"offpeak","meterRegisterId":"1","timePatternRegime":374, ...

...{"tier":2,"clockingTimeId":375,"timeOfUseLabel":"peak","meterRegisterId":"2","timePatternRegime":375, …

The TPRs look like the right ones for an E10 tariff, but they’re applied to the wrong registers. DCC (who collect usage data and readings for suppliers and others to access) expect the first register to record peak usage. I’m not sure whether they look for the tier number or the register ID, but in your case they’re the same anyway. Your first register (tier 1) is recording offpeak usage:
SSC: 0935   TPR: 00374   Timings: All days 0000-0500, 1300-1600, 2000-2200   Name: Off Peak

It seems that when the readings reach OVO, the contents of the first register are wrongly assigned to peak and - more worryingly - billed as such. 

I think this is quite simple to rectify by means of remote commands from OVO’s metering team, so you should contact support (webchat might be best, so you can copy and paste stuff like this post) and ask them to persuade Metering to reconfigure your TPRs: Tier 1 should be TPR 375, tier 2 TPR 374.

At the same time, I’d suggest you ask for your reading frequency to be changed to half-hourly. This gives you much more clarity about your consumption. It used to be the default, but it seems that it’s reverted to monthly during recent meter installations. You should also ask to have your bills corrected for the period from when this started (probably when the meter was installed) up to the date of the TPR fix.

Last, your photos show (I think) that LC2 (the Load Control for your storage heaters) is active, so there should be power to the heaters. If this was during what should be an offpeak period, then the LC is working as designed. If it wasn’t, scream!

Full disclosure: I went through a similar experience following a meter exchange a few weeks ago. Support were able to get the TPRs fixed and the reading frequency changed back to half-hourly, where it had always been previously.

Thank you very much, it looks like that is what's happening. You obviously know your stuff! it's a bit technical for me but I think I've got it!

We shouldn't have to do this sort of investigation, I’ve got time, but what about all those who don't have time or who accept what OVO have set up!

Thanks again, I’ll waste another 3 hours on web chat with numpties who don't have a clue! I’ll let you know how I get on.

Hey @pegem,

Let us know if you have any issues getting through to the support team. 

We have now been told that OVO don't offer E10 & we should never have been offered it! It appears that we had a Smart Meter fitted on Economy 10 with SSE in March. When we migrated to OVO in August Economy 10 wasn't a tariff OVO offered so we have been on E7 since But NOBODY TOLD US!! The local setup still thinks we are on E10 and the heating etc. still boosts for 10 hours per day, but that means 5 hours at expensive heating! The charging pattern on Storage Radiators is still E10 but we have losing  5 hours of cheap electricity a day! OVO are registering on their system, at best E7 at worst flat rate. There's talk of compensation, well see! Disgraceful! We can't be the only customers affect by this.

It explains why it was so difficult to reconcile readings with usage!

That is disgraceful, and I wonder if you were misled. If I visit plans.ovoenergy.com and enter a postcode near yours, then select filters for Electricity | Available for sale | Multi rate | Direct Debit,  I find this option:
  

  
I can’t imagine why they would advertise it for sale, but then claim not to offer it.

Thanks for that, As I understand it E10 is fine on traditional meters, it's so called 'Smart' meters that are incompatible. Why I don't know. Two months I've been trying to get this sorted!
