This tool polls live data from an E3/DC device cyclically and publishes them to a MQTT broker. The polling interval is adjustable.

Note: This is only a wrapper around the great python-e3dc library. Credits for the E3/DC part to the people over there!

Note: This is a very early stage of the project, documentation is not completed and the tool is not fully tested yet.

There is a docker image for this tool.

docker pull mdhom/e3dc-to-mqtt:latest

You can run the docker container using a docker-compose file like the following:

Make sure to replace the <> placeholders with your credentials!

version: '3.3'

services:
  e3dc-to-mqtt:
    image: "mdhom/e3dc-to-mqtt:latest"
    restart: always
    environment:
      - MQTT_BROKER=<ip of your mqtt broker>
      - E3DC_HOST=<ip of your e3dc device>
      - E3DC_USERNAME=<username for e3dc>
      - E3DC_PASSWORD=<password for e3dc>
      - E3DC_RSCPKEY=<encryption key of your e3dc device>
      - ADDITIONAL_PARAMETERS=--interval 5

This tool is also available for running via command line. The necessary parameters are passed via arguments.

If you want to use the latest release without cloning the source code, just run

pip install e3dc-to-mqtt

If you want to use the latest dev commits, you can install the package directly from source:

python -m pip install -e . --user

Make sure to run it from this projects main directory (containing setup.py).

To start the cli tool, just run

e3dc-to-mqtt --mqtt-broker *** --e3dc-host *** --e3dc-username *** --e3dc-password *** --e3dc-rscpkey ***

The tool will then start polling the data from the device and publish it to mqtt.
