EdgeRouter PoE-5 and 3 UAP-AC-LITE Setup

I have the EdgeRouter PoE-5 setup and routing Internet traffic as follows:

   eth0 - Internet

   eth1 - LAN   (10.0.1.1/24)

   eth2-4 - WiFi (10.0.2.1.24)

I've installed the Unifi Controler (v4.8.18) on our server at 10.0.1.10.  DHCP is active on "WiFi" assigning IPs to the WiFi devices.

My problem is when I launch the manager and run the initial setup wizard, it doesn't see any of the WiFi devices as they need to be on the same L2 switch. I was told that this was possible to setup - so is there a way to manually adopt the AC-LITE devices? Or am I missing something.

If needed, I can upload my config.boot file.

Cheers,

M.
