Read smart Luxembourgish electricity and gaz counter values with ESP8266.

Overview

In Luxembourg, electricty and gas counters are being replaced with smart counters that allow the provider to remotely measure consumption values. A special port is provided to allow the end-user to capture the data, for example for integration with home automation systems.

This work is a fork of the awesome project by Guy WEILER who did all the hard work on both the software and hardware side. Please review Guy's website for technical details on the solution, PCB layout, etc.

Features

  • publish all values from the electricity counter to MQTT in their own topic
  • units are published as well in a separate topic for easy of interpretation
  • if a gas counter is connected to the electricity counter, gas volume is published as well (implemented but not tested yet)
  • possibility to work without a counter from a data capture to make quick tests when adding new features
  • extensive logging available on the second UART port (the first one is used by the counter)

Requirements

  • A 'smarty' electricity meter
  • Your personal decryption key, that you need to ask from the provider Creos, giving them your counter number
  • A Wimo D1 mini pro micro-controller and adaptation board. See Guy's website

Usage

  • Download and install PlatformIO. I did not test it with the Arduino IDE.
  • Open the project in PlatformIO
  • Copy the file include/smarty_user_config_sample.h to include/smarty_user_config.h and adjust it to your needs (WiFi settings, decription key, MQTT server).
  • Build and program the Wimo
You can’t perform that action at this time.
