Using an SDR and RTL_433 in docker with MQTT
Summary
Mainly to grab weather station data, but also useful for other 433MHz data, this is the setup I use in Docker. It uses a cheap Realtek USB SDR (software Defined Radio), and pushes data received straight to an MQTT server.
For the weather station it is proving a lot more reliable than using my USB Fineoffset weather station receiver. I’d like to build it back in to weewx though, as software like weewx does a lot of nice summaries/calcs that are necessary, whereas a setup like this just shows live data such as a rain count that is just a total cumulative number of mm.
You can pass the setup parameters to the container as env variables, but I found it more structured to set up a conf file for rtl_433 and tweak that to suit.
This setup will grab a bunch of known RF data for various remotes, transmitters etc and automatically convert the data to values then push to MQTT.
Hardware
This is the USB SDR I have
https://www.adafruit.com/product/1497
I suspect anything with the Realtek RTL2832 chipset in it would be fine however (or others if supported by RTL_433)
Docker Compose
version: '3.3'
services:
rtl-433tomqtt:
image: 'bademux/rtl_433tomqtt:latest'
hostname: rtl-433tomqtt
container_name: rtl-433tomqtt
restart: unless-stopped
volumes:
- /dockervolumes/rtl-433tomqtt/rtl_433.conf:/etc/rtl_433/rtl_433.conf:ro
- /etc/localtime:/etc/localtime:ro
- /etc/timezone:/etc/timezone:ro
devices:
- /dev/bus/usb:/dev/bus/usb
# - /dev/bus/usb/001/002:/dev/bus/usb/001/002USB device and UDEV
rtl_433 looks for the SDR device in /dev/bus/usb/xxx/xxx . This location can change if you unplug/replug the USB device or move USB ports (or reboot).
I set up a UDEV rule to set the owner of the device (based on it’s vendor ID) and let the rtl_433 software just look for it under /dev/bus/usb . It is probably better not to expose all the usb devices this way to the container, but this works.
Note also, the Symlink below is created, and Debian also creates a /dev/swradio0 – neither of which rtl_433 looks for.
This is the UDEV rule and it sits at /etc/udev/rules.d/99-rtl_sdr.rules
# RTL SDR
SUBSYSTEM=="usb", ATTRS{idVendor}=="0bda", ATTRS{idProduct}=="2838", MODE="0666", GROUP="plugdev", SYMLINK+="rtl_sdr"rtl_433 conf file
the main thing to change in the conf file is the mqtt server address, and change the mqtt topic too if you wish (I’m using rtl_433 as the topic). The data will be pushed to mqtt under this topic, then protocol number then channel number.

Notes
I was getting errors after enabling more than about 148 protocols in the rtl_433 conf file. Not sure why and haven’t investigated further.
This is how to determine which /dev/usb/bus ID the device is on. It might be better to pass this as an env variable and expose this device only.
vidPid="0bda:2838"
devPath="/dev/bus/usb/$(lsusb -d $vidPid | sed 's/^.*Bus\s\([0-9]\+\)\sDevice\s\([0-9]\+\).*$/\1\/\2/g')"
chown $USER $devPath
