Device tracking - Router

Hi,

Do I understand from postings that if I want device tracking based on devices connected to my router ( RT-AC66U) I only need

asuswrt:
  host: 192.168.1.1
  username: admin
  password: password

and not

device_tracker:
  - platform: asuswrt
    host: 192.168.1.1
    username: admin
    password: password
    new_device_defaults:
      track_new_devices: true

Running the latest HA 0.110.5 (soon 0.110.6)

Right?
