RFLink USB Gateway - Help needed

[Captain]

I've recently rebuilt a headless Raspberry Pi 3B+ with Domoticz in a Docker container.

When I attempt to add RFLink USB Gateway, the Serial Port dropdown is blank and does not allow a manual entry. What am I missing? It worked on the same hardware in the previous build.

Thanks,

Which Docker container? And did you follow the rules to install the container?
For instance: https://hub.docker.com/r/demydiuk/domoticz

Thanks,

In the new light of the morning I did go back and read the docs - and I found what I was missing.

Passing Through USB Devices
To get full use of Domoticz, you probably have a USB device you want to pass through. To figure out which device to pass through, you have to connect the device and look in dmesg for the device node created. Issue the command 'dmesg | tail' after you connected your device and you should see something like below.

usb 1-1.2: new full-speed USB device number 7 using ehci-pci
ftdi_sio 1-1.2:1.0: FTDI USB Serial Device converter detected
usb 1-1.2: Detected FT232RL
usb 1-1.2: FTDI USB Serial Device converter now attached to ttyUSB0
As you can see above, the device node created is ttyUSB0. It does not say where, but it's almost always in /dev/. The correct tag for passing through this USB device is '--device /dev/ttyUSB0:/dev/ttyUSB0'

so creating the container now looks like this ...

docker create \
--name=domoticz \
-e PUID=1000 \
-e PGID=1000 \
-e TZ=America/New_York \
-p 8080:8080 \
-p 6144:6144 \
-p 1443:1443 \
-v /media/Media4/DockerContainers/domoticz/:/config \
--network macvlan \
--ip 192.168.1.27 \
--device /dev/ttyACM0:/dev/ttyACM0 \
--restart unless-stopped \
linuxserver/domoticz:arm32v7-latest

I'll also take a look at https://hub.docker.com/r/demydiuk/domoticz
