Issue Getting Historic Data from Honeywell Smart Meters

I wanted to create this post to highlight that there is an issue accessing Historical smart meter data (the 13-month history) from Honeywell smart meters.

It seems there is a fault with Honeywell's implementation of the DCC standards that mean consumption data is not getting forwarded onto registered DCC Other Users (of which Hildebrand is one). This is preventing people like myself from accessing our historic records via the Bright app or Glowmarkt API.

I've been made aware that this issue has been escalated with the DCC (who manage the SMETS2 infrastructure) and that they are in discussions with Honeywell.

I would hazard a guess that Honeywell didn't test compatibility with DCC Other Users fully before rollout, but with the ability for SMETS2 meters to receive firmware updates, they can hopefully rectify this issue (but who knows how long that'll be).

I'd like to add that since receiving my Glow IHD/CAD and connecting it to wifi, I have access to the full consumption history from that point forwards just not the 13-month prior history that is usually stored by the smart meter.


  • the meters store 30 days worth of half hourly data and 13months worth of daily register reads. the issue with the meter not returning the data will not be to do with the otheruser not being tested, as that is a DCC specific restraint, it is likley also happening with any user that tries to request data from the meter. That could be a meter specific problem, or it could be a DCC issue with the size of the message being sent. its possible if you requested the data in smaller chunks, like a week a time, you may be more succesful.

  • For the record - the issues is with the version of firmware on the Honeywell meters. We are seeing it less frequently now as suppliers are obliged to keep meter firmware up to date.

    This is what we advise customers who have Honeywell meters and aren't getting their electricity data via Bright:

    Our advice is that you need to submit a request to your supplier's Smart Meter Technical team and tell them the following (and we are a DCC Other User which is how we know about this, in case they ask):

    Please could you update the firmware on my Honeywell meters so that a DCC Other User can access my consumption data. The firmware version that corrected the issue was released in November 2020 and the details are as follows:

    Release details:

    New Firmware Version

    ASP09.01.40.09 / ASP09.02.40.09

    New Firmware Version in CPL format (Hex Value) /

  • Has anyone had success getting Scottish Power to update their Honeywell firmware? I asked their support team to upgrade mine and they couldn't help me. They said I can just download their app to check my usage...

  • Hi @kk_sonata,

    Sorry to hear that SP aren't making this easy - I think we've had another SP customer have success with their request. I also believe that energy suppliers are obliged to keep firmware up to date.

    Did you ask for the Smart Meter Technical team? You are within your rights to raise a complaint and if that isn't dealt with satisfactorily, go to Ofgem - but hopefully you can get to someone more helpful at SP.

    Best, Jane

  • Hi, just checking in on my Scottish Power saga in case anyone else is following. I tried calling them a few times, but got various responses from CSRs. E.g. suppliers aren't responsible for smart meter firmware upgrades, there is nothing they can do as long as my meter is sending readings, and in one case, the rep felt that 3rd parties aren't allowed to access smart meters due to privacy/security risks.

    I ended up filing a formal complaint, which is now with the smart meter team. However, the complaints handler said that SP only upgrades meters in batches and has no way of upgrading a single meter on request. I did point out that the new firmware was released in 2020, and suppliers have a duty to keep meters updated. I hope to hear back from them next week, and will go to Ofgem if the complaint is unsuccessful.

  • Thanks for the update @kk_sonata - sorry to hear that it is such a saga. A few suppliers do this as a matter of course. Well done on keeping up the pressure - you have to be within your rights!
