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

Jane and her colleagues at Glow/Bright/Hildebrand have done a lot to help with this issue. It doesn’t help that the meter manufacturer nor DCC seemed to know what was happening.

Having been one of those impacted originally, I’m of the opinion that a firmware update caused the issue and it required a further update to clear the problem.

I still have the problem so no firmware update for me 😔

These are the last reading pulled by Glow/Bright - nothing since 19th June 2024

@sraper my Aclara meter stopped communicating last October. The eventual fix was to replace the meter, which was done in June. DCC/supplier were unable to get to the bottom of the issue of why access was being blocked. Hope you manage to get a resolution soon.

Problem is as the meter is sending information to my energy supplier (not OVO) they dont care - so no way they will replace the meter as they dont deem it to be faulty. 

Just 3rd party access is broken

Could be worse Jane - imagine if Trilliant managed to get a hold on SMETS2! 😜

Now THAT would have been fun...

I’ve just started trying to download my data using the Bright website. The “Day” data downloaded seems to be surprisingly wrong when compared to the half-hourly data downloaded. 

For example, one day when the usage from the half-hour figures (and other sources) was 34kWh, the Bright Day data indicates 46kWh.

Out of around 400 days of Bright day-data, only 140 are within 1kWh of the equivalent half-hourly figures.

Am I missing something?
