This project is about integrating realtime data acquisition with the Landis & Gyr power meter and transmitting the the data to a MQTT broker. WiFi password, SSID, broker ID, broker password, broker port and MQTT url can be typed in via the console interface and stored in the NVS Flash. Data capture is done with the ESP32C3 microcontroler via the UART port on GPIO_6, see the schematic in the CAD folder. There is also a Freecad project in the CAD folder comprising an enclosure for the ESP32C3 with space for the interface to the Landis & Gyr power meter.
