ASUSWRT entities without parent devices unavailable

Configuration
1

My ASUSWRT integration is set to integrate unkown devices & activate added entities but I still can’t track all devices connected to my router.

I see all devices in ASUSWRT’s debug info (“tracked_devices” in the debug JSON), and ASUSWRT also creates entities for all of those; but only the entities registered/added to devices that were already created by other integrations before (e.g. sonos, shelly, tasmota, lifx or any other wifi based integrations) are actually working. All the other ones are disabled/unavailable and can’t be used.

How can I configure ASUSWRT to enable device_tracker entities without a parent device, e.g. for mobile phones?

Router: Asus RT-AX92U (x2, mesh)

A github issue comment lead me to the solution:

Apparently the not-showing of device tracker entities without parent devices is a default HA behaviour and has nothing to do with ASUSWRT.

To track any device just enable the respective device_tracker entity from within HA and you’re good to go!
