Dockerfile

#
# Docker file to create an image that contains enough software to listen to events on the 433,92 Mhz band,
# filter these and publish them to a MQTT broker.
#
# The script resides in a volume and should be modified to meet your needs.
#
# The example script filters information from weather stations and publishes the information to topics that
# Domoticz listens on.
#
# Special attention is required to allow the container to access the USB device that is plugged into the host.
# The container needs priviliged access to /dev/bus/usb on the host.
#
## Starting with docker run
#
#docker run -d --rm \
#  --privileged \
#  -v /dev/bus/usb:/dev/bus/usb \
#  --env MQTT_HOST="mqtt.example.com" \   # Required
#  --env MQTT_TOPIC="sensors/rtl_433" \   # Default="sensors/rtl_433"
#  --env MQTT_PORT=1883 \                 # Default=1883
#  --env MQTT_USER="" \                   # Not Required
#  --env MQTT_PASS="" \                   # Not Required
#  --env MQTT_QOS=0 \                     # Default=0
#  --env DEBUG=False \                    # Change to True to log all MQTT messages
#  --name rtl433-to-mqtt \
