Russound RNET TCP to Serial gateway Docker Container

I spent some time this weekend getting my Russound CAA66 set up with Home Assistant, which needs a TCP to Serial gateway. Mine is plugged into a different Raspberry Pi on the network, and its python environment is not in the best state. So, I threw a Docker container together to run the service, and it’s running great. I figured I’d share here in case anyone else stumbles upon it while searching. Code is at or you can spin it up by running:

docker run -itd \
  --restart always \
  --device /dev/ttyUSB0 \
  -p 7777:7777 \
  --name tcp_serial_redirect \ \
  python --rts 1 --dtr 1 /dev/ttyUSB0 19200

You may need to replace the two instances of /dev/ttyUSB0 with your Serial Port if it differs. The container is built for ARMv6, ARMv7, ARM64, and AMD64, so it should run on whatever device you need.


Thank you! This helped me so much getting mine setup.
