[Limited offer] Echelon/NES Smart Meters – MEP interfaces modules and kits

This is a follow up on our previous Echelon/NES Smart Meter post.

We have released all our Hard- and software on GitHub here: https://github.com/dabblerdk, so your cheapest way of getting started if you have soldering skills is to order a PCB and components – and start building your own modules.

We hope that someone will pick up the task of producing/selling kits and assembled modules, but we have decided to offer some ourselves for a limited time to get more people involved.
Note: The price is set so others will have a chance of under-bidding us, that is on purpose.

If you buy one of our modules we expect you to participate in the project in some way. It could be as simple as write your story/experience about the project (as a guest writer on www.dabbler.dk or on the OSGP Alliance GitHub site), or if you have the skills you can help develop/improve the hard- and software.

We have two options:

  1. The MEP module as a kit, all components included. The ESP32 is a 16MB version.
    You are required to have the tools and skills, to assemble the PCB, adjust the buck converter and program the ESP32.
    The PCB/components are classic through-hole-technology (THT) so you don’t need to have good SMD skills.
    But note that the ESP32 is a separate PCB with castellated holes (that is kind of like SMD).
    As the module is NOT assembled, we cannot test it or install the software. You’ll have to do that yourself.
    Price: 300 DKK including freight in Denmark (payment due before shipment (bank transfer, PayPal or Mobile Pay).
  2. An assembled MEP module. The ESP32 is a 16MB version.
    The Module is flashed and should boot into Access Point mode when mounted in the Smart Meter. You should then be able to go to the homepage of the module and configure it to use your WIFI. Here you will also be able to enter the MBK key you got from your Power Company.
    PCB and components are mostly classic through-hole-technology (THT), but the ESP32 is a board with castellated holes.
    We might also choose to provide SMD versions at the same price depending on component availability. You will be asked if SMD is OK with you before shipping.
    Before shipment we will make sure the module boots correctly in our Smart Meter, but we won’t perform a long/extensive test of the module.
    Price: 500 DKK including freight in Denmark (payment due before shipment (bank transfer, PayPal or Mobile Pay).

This is a prototype project without ANY form of warranty. Any use of this module is your risk and costs!
We cannot gurantee delivery times as we purchase most components from China to keep the cost low. Delivery times may vary from 0 to 2 months or in special cases even longer.

AS we currently have no experience with the IR solution, we will NOT be providing any hard- or software for that at this point.

Please send an e-mail to gert@dabbler.dk and graves@dabbler.dk, stating if you want a kit or an assembled module. Also state your shipment address.

Please let us know if you have any questions.

  1. Hi all,

    Unfortunately the demand for these modules have been far larger than expected.
    Thank you so much for your interest in getting involved!

    We are currenly out of PCBs and components, but have ordered extras – delivery time is expected to be 6-8 weeks.
    If you would like a module, please let us know ASAP so we can put you on the back order list.
    Note: You WILL get a second chance to cancel your order when we are ready to ship the module or kit to you.

    People already on the back order list HAVE been notified, and will also get the option to cancel their order when new PCBs arraives.
    If you did not hear anything from us, your module or kit is currently beeing assembled and we will reach out to you when it is ready for shipment/payment.

    Best regards,
    Gert Lynge,

  2. Hi all,

    Next shipment of components has started to arrive before we expected, but demand is again far higher than expected.

    We are currently assembling/shipping the 2nd batch of modules and kits – so if you ordered, please keep an eye on your e-mail.

    Unfortunately, we will soon be out of components again and still with several backorders. We never imagined how many would actually be interested in this!

    We have ordered more a few weeks ago, so waiting time should be a few weeks by now – we hope everyone is patient and apologize for the delay.

    Best regards,
    Gert Lynge,

  3. Hej,
    Det er et mega spændende projekt i har skubbet i gang – godt arbejde.
    Jeg kan ikke helt se løsningen for mig.
    Er det muligt at ligge et billede af et print med komponenter på GIT eller denne side?

  4. Hej Michael og tak for din interesse.
    Vi har lidt problemer med at følge med efterspørgslen, men jeg skal prøve at tage nogle gode nær-billeder når vi får lavet næste batch. I mellemtiden er der billeder her (printets fysiske udformning har ikke ændret sig meget gennem tiden – der er kun flyttet lidt rundt på og tilføjet/fjernet nogle passive komponenter):

    * De nyeste print kan ses her: https://www.dabbler.dk/index.php/2022/04/03/echelon-nes-smart-meters-dabbling-the-hardware-v1-10-and-v2-00/

  5. Hi Gert.
    I have the module up and running, thank you for a great product. I have been looking on the upgrade procedure on the git page. You state that the updated .bin and .wwws files should be located at a path which is a windows path. Where is the download location of the updated files?

    1. Hi Jens,
      You’ll find the latest software here:
      – bin-file: https://github.com/DabblerDK/MEP-SW-ESP32/blob/main/NES-MEP-UI/build/esp32.esp32.esp32doit-devkit-v1/NES-MEP-UI.ino.bin
      – wwws-file: https://github.com/DabblerDK/MEP-SW-ESP32/blob/main/NES-MEP-UI-SPIFFS/update.wwws

      The wwws-file is basically a merge (with some extra stuff) of the other web-files (js-, css- and html-files etc.). The script to “compile” it from them is included if you want to change anything.
      The bin-file is the source code compiled…

      Best regards,
      Gert Lynge

  6. Its alive here as well.

    1000 thanks for all the work. Not least getting the documentation released, but also providing these prototypes

    Its very much appreciated.
