A bridge between the serial interface (RS485 or infrared) of certain power meters and MQTT with Home Assistant support.
This is intended to be deployed on a device that has a physical serial connection to a power meter manufactured. It has only been tested with the following models:
- Landis-Gyr: ZMD3104107.B40 using the configuration file
etc/landis-gyr-config.toml - Logarex: LK13BE803039 using the configuration file
etc/logarex-config.toml
Please contribute experiences with this or other models in an issue.
The application may be deployed from source or as a container.
To deploy from source use poetry to install or build a wheel.
The included Dockerfile contains build instructions for an image based on Alpine Linux. The recommended way to build and deploy it is podman:
$ podman build --rm -t py-power-meter-monitor:latest .
$ podman run \
--device /dev/ttyUSB0:/dev/ttyUSB0 \
--volume $(pwd)/default-config.toml:/home/py-power-meter-monitor/config.toml:ro \
localhost/py-power-meter-monitor:latest --config-file config.toml
The configuration file allows for parameterization of various aspects:
- the serial connection
- the mqtt connection
- the OBIS data sets to send
I welcome requests, bug reports and PRs.
