Third-party access to smart meter data: recent failures

Many of those who are used to retrieving their usage data from third parties have noticed an interruption in the service recently. For me, it started on 13 June and has yet to be resolved.

Third parties (called ‘other users’ by DCC) are supposed to be able, with the customer’s permission, to contact a smart meter and retrieve usage and tariff data stored in it, which they can then present in a friendly form and also make it possible to download the data. This is in many cases a more efficient system than what suppliers offer via their websites.

So far, we’ve heard from customers using n3rgy and Hugo, and also apps like Loop which piggyback on n3rgy to get the data. It appears that only those with Aclara meters are affected, although this may be a red herring: all of the affected customers I’ve come across have indeed Aclara meters, but another common factor is the communications hub - in all cases WNC. Both n3rgy and Hugo say that their credentials are not being accepted when they try to retrieve data, which suggests a fault with the secure DCC network rather than the meter itself. 

  • Can the mods get an update on this error from those responsible?
      
  • Will anyone having this problem please reply here and say so?

It would help if you could give your region (the first two digits of the 13-digit MPAN), your supplier, the time stamp of the last data packet received and the make and model of the meter and the communications hub. Here are my details for starters:

Region 11 (East Midlands)
Supplier OVO
Meter Aclara SGM 1416B
CH WNC SKU1
Last data packet 13/06/2024 03:00

Hey ​@sraper,

 

I’m really sorry to hear about the access issues you’re facing! It sounds frustrating. Maybe ​@JaneatGlow can jump in and help us figure out what’s going on?

 

Let’s keep our fingers crossed that we find a solution soon and get everything sorted out for you!

Hi both,

As of this morning, we still have almost 100 of our Glow users with an Aclara meter not getting data - and believe that any other ‘Other Users’ have the same issue. It is frustrating as of course it isn’t a priority for either the supplier, understandably as they are getting what they need to generate a bill, or the DCC.

Not that it helps but we’ve got a similar problem with a subset of Kaifa meters - but in that case there seems to be no pattern of model/firmware/comms hub variant…. 

And to think we put all this time in for what is a free service to the market on our part! 😂

Sorry not to have anything more positive to update on.

Thanks for the update

While I concur that OVO may not be entirely responsible for the issue, they must assume accountability for the situation. Customers are advised to contact their supplier, who should then engage in direct communication with the DCC.

 

This process should not be overly complex. My issue has persisted for more than six months without any resolution in sight.

 

It is important to note that I am deeply appreciative of Jane and the team’s efforts in providing information. However, OVO has proven to be utterly ineffective in addressing my concerns.

OVO receive the meter reads correctly - just the electric data is missing for 3rd party apps since March.

I think you’ve made the point here .. if OVO are getting your usage readings then they have (almost) no interest in access by third parties. 
All suppliers - as far as I’m aware - also don’t get their data directly from DCC but use another organisation as an accumulator to get what they require to enable operation and billing. So I’m not surprised that support staff as generally not aware of DCC. 
Add to that, neither the meter manufacturers nor DCC fully understand why the situation exists for some customers and so it has been down to the third parties themselves to try to figure out and get something done. 
This also has affected a number of different suppliers .. I myself had the problem however I am not supplied by OVO.

Hello all,

This situation is nothing to do with OVO at all - other than the fact that they host the forum where the topic is under discussion. The only entities that can (potentially) resolve it are the DCC and the meter manufacturer. They are working on it but it feels as though the root cause is still unknown.

While I’m here, it is also really important to appreciate that the DCC are not the data repository, your energy meters are the data repository. The DCC are the secure conduit to that data.

The meters in question, and they are only a small subset of all that type of meter, are not responding to a request to return their readings from a DCC Other User (Hugo sub-contract n3rgy’s service who are the Other User for them). Then, for no apparent reason, we see some of them recovering.

The good news is 1) I don’t believe we’ve seen any new meters in this state since June, and 2) there is investigation underway (sometimes it takes a very long time to get to that point).

This is happening to me.  Roughly a month ago the Electricity data stopped showing up in loop.homes app.  The Gas readings are fine in Loop, and both are fine according to Ovo.

 

My meter is an Aclara SGM 1411-B, and the first 2 digit of the MPAN are “19”.

 

Is this something Ovo can help with?

Hi, if you’ve read the post above yours you will see that the situation described in this thread is nothing to do with any supplier but one needing intervention from DCC who are a central router for all data.

Of course, your own situation might be different and so asking customer support to check your meter connection might be a good first step. My own situation was solved by a meter software update.

If you are missing data just in Loop, it would be worth asking them.

Short answer: No.

Loop have made big changes to their data retrieval processes starting on 28 March, and it appears that not all users are unaffected by the change. It should help to remove the Loop app, then re-install and set up a new account.
  


 

Many of us used Loop or Hugo or both, primarily as middlemen to getting data from n3rgy. Loop have stopped using n3rgy since their takeover by Procode, and Hugo have shut down their free offering, so no n3rgy data.

I tried this morning signing up with Equiwatt. The process was quicker and simpler than with either of the others, requiring only the MPAN and the last quartet of the IHD GUID. Once confirmed, the new relationship was recorded almost immediately by n3rgy and my data were again available from there.

Hello everyone,

This is Jane at Hildebrand - we offer the Bright App and the glowforhomes.com sites.

Unfortunately it looks as though the Aclara meter problem has started again - we’ve a number of customers whose electricity data stopped around 20/21 May.

We are in discussions with the DCC to see if they can identify what might have triggered this.

Best,

Jane

Hey, thanks for the heads up ​@JaneatGlow !

Keep us posted just in case you have any news. By the way, did DCC ever fix that Trilliant issue?

Please, that Trilliant issue… Between that one and Aclara I shall feel very discouraged! Talk is that they are making progress on agreeing with Trilliant a plan for remediation…. I suspect that will take as long as the meters being replaced anyway as they are at end of life (sorry to be a cynic!).
