Can't locate RfxTrx usb device on Hass.io

Installation Home Assistant OS
1

Hello!
I just installed hass.io and try to figure out how to access the rfxtrx usb device.

Have installed SSH and I can’t find it in /dev/. Is it not supported yet or have I missed something?

Acording to releaselog devices are supported since 0.28 but I can’t find any info on how to use them.

Found the command to list devices but it doesn’t list any devices…
“http://192.168.1.201:8123/api/hassio/homeassistant/info”
{“result”: “ok”, “data”: {“version”: “0.45.1”, “last_version”: “0.45.1”, “devices”: []}}

3

Can you post a link they describe a setup under “normal” systems?

4

I don’t understand what you want me to post…

I am having the same problem connecting usb devices to hassio. Anyone that can offer some insights or a solution?

When you login with SSH execute the following command

dmesg | grep tty

Results: [ 4.776763] usb 1-1.2: FTDI USB Serial Device converter now attached to ttyUSB0

In configuration.yaml file

rfxtrx:
device: /dev/ttyUSB0

Then it should work

Install the SSH addon and login to the machine.
Run below command and it’ll display the applicable USB paths.

core-ssh:~# hassio host hardware
{
  "serial": [
    "/dev/ttyUSB0",
    "/dev/ttyUSB1"
  ],
