I may have shouted too soon.
Looking like the change might have been effected yesterday.
Can’t see timely data through OVO methods.
Third party apps are sowing the load to the ECO10 seemingly now but such graphs are supplied a day later.

It will be encouraging to many RTS migrants that you were able to be moved from Economy 7 to Economy 10. We have seen all sorts of claims that this can’t be done, or that it can only be done by a visiting engineer.

We have seen so often that the ALCS isn’t configured to match the ToU regime on the meter itself (or indeed configured at all). This can be done remotely, but there may be a delay - often a few days - between the request reaching the desk of a smart team member and the update being transmitted successfully to your meter. So yes, you may have shouted too soon.

If your IHD is now working again (it’s not clear what happened there), its orange or red traffic light may be your best indicator that the heaters are charging up. Otherwise, some storage heater owners have replaced the switch or socket supplying a heater in view with one fitted with a neon pilot that lights up when the circuit goes live.

My water heater is on the same circuit as the space heaters; its timer switch has a red lamp that lights up when the immersion heater is working.

It’s probably been almost a month since they said they had made the changes.

Last week I wrote saying the ALCS wasn’t operating to ECO10 and they seemed to go at a tangent saying they would do something to the IHD it lost connection and hasn’t recovered since.

OVO account portal and app both say they are not compatible with complex meter so I’m reliant on third party apps which have a delay.

Yes I had been fed they couldn’t change the ALCS through from when they first said they could but obviously something changed or finally clicked into place.

Hi @Colinyguard,

I can see our forum volunteer has already stopped by with some advice here.

Glad to hear that the ALCS issue has been sorted for you.

Have you tried resetting your IHD? Maybe turning it off and on again may help reset it. If you’re able to let us know which IHD you have we may be able to advise further.

Yes tried switching it off and moving it closer to the meter to no avail.

IHD3 Model CA3100002 Type 1

Don’t particularly need to use it as most times I know what I’m consuming.
Would have been handy for observing when the load was applied to the storage heaters during this schedule upgrade.

I remain confused by some of the OVO help guidance as it implies the supplier fetches the meter reads from the IHD and the operative also believed her doing something to the IHD would resolve the ALCS issue.
Whereas I thought the IHD was just a slave readout device from meter held data.

Whatever ALCS issue has been resolved whilst IHD defunct.

You are absolutely correct in that the IHD is simply a remote display. It has no part in any billing, circuit switching or otherwise.
If you are not concerned about its use then fine as it doesn’t affect anything else but I’ll just mention that those devices (IHD’s) can retain settings for quite a while after power down. It’s recommended to remove power for some 2-3 minutes before reconnecting to reset - you may have tried that but just in case. 

 Just putting my pedant hat on for a moment …
    

Some IHDs (including, I think, ones commonly provided by OVO) are also PPMIDs - Pre-Payment Meter Interface Devices. They can be used to top up the meter without having to wrestle with the meter itself - a function that might be classified under billing.

There are also allegedly IHDs capable of switching auxiliary loads (typically EV chargers) on and off, so-called HCALCS. I’ve never spotted one in the wild, though. 

This is not likely to be of much interest to @Colinyguard, though, so I’ve only added it for completeness.

However, Colin might try running this little utility which - if it works - will reveal any problem with the Home-Area Network (HAN). Any warnings about expired security certification can safely be ignored, but any others may be of interest. Visit this page: n3rgy data Smart Meter check, enter the 13-digit MPAN and tick the tiny confirmation box.  

The one thing that i see that puzzles is:

For the meter

Security Expiry Date: 2023-08-30 00:00:00 - Warning: Security Certification will expire in less than 3 months or has already expiredWhich is a date prior to installationThe communications hub on the other hand is dated through to 2029

Thanks. Perhaps you didn’t notice where I wrote Any warnings about expired security certification can safely be ignored …

I’m assuming that you see a section about the IHD that doesn’t show any warnings at all. If on the other hand the IHD section is missing, I think that means that it’s been un-paired (disconnected from the meter), which may have been what the support agent did. @Blastoise186 should know …

For reference, this is what I see:

Yes would probably guess they have unpaired it.
Third party apps that rely on the GUID can still view the data.

That’s what it looks like. Try Support again and hope to get someone who knows what they’re doing.

Please keep us posted with how you get on @Colinyguard, your advice might be helpful for other community members in a similar scenario.
