ESP32 SmartMeter

This project reads out the meter values of an ISKRA MT681 via an IR reader. It then takes these values and sends them as payload to a MQTT-Broker, where they get converted to a prometheus metric via kpetremann/mqtt-exporter and then read into prometheus.

Installation

  1. Install the ESP-IDF

  2. Clone this repository:

    git clone [email protected]:christian-heusel/esp32-smartMeter.git
cd esp32-smartMeter

  3. activate esp-idf in current terminal session

    . $HOME/esp/v5.2.1/esp-idf/export.sh

  4. Configure the project

    idf.py menuconfig

    And especially insert sensible values into the MQTT & Wi-Fi Configuration

  5. Build it & flash it
