Thanks to our friends at www.ustepper.com hardware to IoT enable your NES/Echelon meter is now available again.
You can purchase it directly from their shop here: https://ustepper.com/shop/home/26-esp32-c3-dabbler-mep-interface.html
Note, although this is a completely redesigned hardware based on a different ESP32 module (it uses the ESP32C3 and not the ESP32-WROOM-32 of our original module), we have extended our software to also support the new hardware.
The source code is the same, and the board selection configures the software so i will run on the chosen module. Simply select the “ESP32 Dev Module” board for the “dabbler hardware” and the “ESP32C3 Dev Module” board for the “uStepper hardware”.
You will also need the .wwws files for both versions.
As always you can find our updated software on our GitHub here: https://github.com/DabblerDK/MEP-SW-ESP32
As always other small fixes and improvements were done and going forward we’ll plan to keep supporting both hardware versions.
Hi
I have got one of the boards, works fine.
But is there a way to get my webserver to collect data from it, to make some statistic?
Hi Allan Kok,
You’ll have to develop something yourself or use Home Assistant, Homey or something similar.
If you want to develop yourself, you immediately have two options to read data from the module:
1. The module runs a simple webservice: if you look into how the Dashboard page is made, you’ll see that it refreshes data by calling a webservice (the refresh is implemented in JavaScript that runs in your browser)
2. The module have some MQTT support. I don’t know much about it as I’ve never used it. But I guess you can also use it.
Note: I believe that Homey uses the webservice, while there are two Home Assistant integrations out there – one uses the webservice and one uses MQTT. But as I don’t use Home Assistant and/or Homey myself, I don’t know much about the integration, but you can find more info. here:

– Home Assistant: https://www.dabbler.dk/index.php/2022/02/20/guest-writer-echelon-nes-smart-meters-home-assistant-integration/
Please share your solution with us so others can get inspired too! 🙂
Hi Gert
I have got my webserver to pass the home page for data, it just only word as long the login session work, here after it want my to login agian.
Can I get the data without logging in?
Yes, the webservice don’t require that you login.
Also the Dashboard page does not require login.
If you need the other pages to be available without login you’ll have to modify the software yourself.
