# ESP32 SmartMeter

This project reads out the meter values of an [ISKRA MT681](https://wiki.volkszaehler.org/hardware/channels/meters/power/edl-ehz/iskraemeco_mt681) via an [IR reader](https://wiki.volkszaehler.org/hardware/controllers/ir-schreib-lesekopf). 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`](https://github.com/kpetremann/mqtt-exporter) and then read into prometheus.

## Installation

1. Install the [ESP-IDF](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/get-started/index.html#manual-installation)

2. Clone this repository:

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

3. activate esp-idf in current terminal session

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

4. Configure the project

```sh
idf.py menuconfig
```

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

5. Build it & flash it

```sh
idf.py build
idf.py flash
```

## Visualization

Import the grafana dashboard in [contrib/grafana-dashboard.json](https://github.com/christian-heusel/esp32-smartMeter/blob/main/contrib/grafana-dashboard.json)
