Core: Component: RF-Link - Doesn't work on latest HASS.IO

[kodarn]

Running the latest HASSIO release running on Raspberry PI 3

*Component/platform: RFLink *

Description of problem:
Attempting to connect my RF-LINK using the RF-LINK-plugin/component.

HASSIO detects the device, which can be seen in dmesg:

dmesg

However, the /dev/serial/by-id/usb-id01234 directory (as described in the documentation) doesn't exist:

Expected:
The device should popup at /dev/serial/by-id/usb-id_____ as described in the documentation at https://home-assistant.io/components/rflink/

when using hassio, your usb devices are redirected to /dev/tty... so in your configuration you can put /dev/ttyACM0

[kodarn]

Awesome! So this is just a documentation error! :-)

I added the following lines to /config/configuration.yaml

rflink:
  port: /dev/ttyACM0

logger:
  default: error
  logs:
    rflink: debug
    homeassistant.components.rflink: debug

After a reboot, the log was populated with RF-Link entries, so I guess everything is ok :-)

I got the hint installing a Z-wave usb stick: https://home-assistant.io/hassio/zwave/

[kodarn]

@aequitas perhaps should know about this.

[aequitas]

This issue is not Rflink/HASS specific but more Serial/HASSIO specific. I think it might be best to reraise this issue on the Hassio repository: https://github.com/home-assistant/hassio

If you have multiple serial devices the approach of using a numbered instead if 'id' based serial device might cause things to break if after a reboot the devices are detected in a different order ('id' based are unique across reboots/installations).

FWIW, I'm using Hassio 0.64 for my configuration with the latest hass 0.54 and it's working fine with id's. Don't know which version you are running?

[kodarn]

http://hassio.local:8123/hassio/advanced shows:

Supervisor
Version = 0.64
Beta channel = false
Latest available version = 0.64

Home Assistant
Current version = 0.54
Latest version = 0.54

[aequitas]

Same versions here, I'm using the RPi3 images, maybe that might make a difference? I don't remember if I did anything special to make it work.

Closing since issue is with hassio serial device handling and original issue seems resolved.
