RFLink & Synology - How to find the port?

Configuration
1

I have connected an Arduino with the Nodo RFLink to my Synology DS920+.
In this doc I see a port that needs to used in the configuration.yaml.

How do I find the port the Arduino is on?
It’s being recognized in DSM, since I see “Mega 2560 R3 (CDC ACM) - Arduino SA” in the Synology DSM Infocenter.

In your HA instance, you should be able to see the connected USBs in:
Supervisor> System> Host> … > Hardware

It may be something like:
/dev/serial/by-id/usb-1a86_USB2.0-Serial-if00-port0

Thanks for your reply.
I found the port here

And added it to the configuration.yaml like so:

# Example configuration.yaml entry
rflink:
  port: /dev/serial/by-id/usb-Arduino__www.arduino.cc__0042_75130303735351611282-if00

# Example configuration.yaml entry
light:
  - platform: rflink
    automatic_add: true

sensor:
  - platform: rflink
    automatic_add: true

# Example configuration.yaml entry
logger:
  default: error
  logs:
    rflink: debug
    homeassistant.components.rflink: debug

Restarted HA after that change.
When switchin on/off the RFLink devices/plugs, I do not see them appear in HA dashboard.

Is there a way to investigate more?

UPDATE:

I see this in the log file:

This looks like the signal is received, but no new device is added. How do i make sure HA adds the device?

Rflink does not know the difference between a light and a plug. Plugs will be added as lights, you need to move them manually to switch (in .yaml)

Thanks for your reply.
I see them in the devices section, but they don’t have a unique ID.
Can you show me how to add them to the configuration.yaml, so I can use them as switches?

Under switch:

  - platform: rflink
    device_defaults:
      fire_event: true
      signal_repetitions: 2
    devices:
      kaku_000041_2: 
        name: something
      kaku_000041_3: 
        name: aswitch
