Reads out a dutch smart meter using the DSMRv5 protocol and publishes some of the stats out to an mqtt broker.
For parsing the data telegrams I use a modified version of the dsmr5 crate,
you can view its source here.
The following environment variables can be configured:
| name | meaning | default |
|---|---|---|
| MQTT_HOST | The address of your MQTT server (IP or FQDN) | ::1 |
| MQTT_TOPIC | The topic prefix | dsmr |
| MQTT_QOS | The MQTT QOS | 0 |
| SERIAL_PORT | The port to listen to | /dev/ttyUSB1 |
To build for all platforms, use
docker buildx build --platform linux/amd64,linux/arm64 -t dsmr2mqtt .
