Dockerfile to help containerize some functionality from https://github.com/merbanan/rtl_433. Specifically publishing recieved device messages to an MQTT broker.

Connection details for the MQTT broker are handled via the following environment variables:

• MQTT_HOST host for mqtt broker
• MQTT_PORT mqtt port, defaults to 1883
• MQTT_USER mqtt username
• MQTT_PASS mqtt password

Since rtl_433 uses USB attached SDRs you'll need to pass through the device to container (this requires the privileged flag).

For example, with docker compose:

  rtl433:
    build:
      context: https://github.com/rh0/rtl433_to_mqtt.git
    image: rh0/rtl433_to_mqtt:latest-dev
    container_name: rtl433
    restart: always
    env_file:
      - ./rtl433.env
    privileged: true
    devices:
      - /dev/bus/usb:/dev/bus/usb

If all goes well and your radio is in range of a 433mhz device broadcast, your MQTT broker should start receiving messages from those devices in the rtl_433 topic.
