So I had one of these laying around and decided to mess with it this weekend.
For those not familiar with this device (https://inwall.ui.com/) it has one port in the back that provides POE and the main ethernet. There's two network connections on the bottom with the one on the left providing pass-thru 802.3af power.
Installation of OpenWRT is the same as any other UAP AC device. I tried both the unifiac-pro and unifiac-mesh-pro images since both of those have multiple ethernet ports on them and the regular unifiac-pro seemed to work the best so far.
Pretty much everything works including both 2.4 and 5 GHz radios but I have a few outstanding problems
-- the "main" ethernet port on the back that powers it does not seem to be recognized by the kernel. No matter what I've done so far I haven't been able to get it to work on network. The secondary one on the lower right works fine, though, so it can get power from one and a network connection from the other
-- Last time I checked, and blew out a USB ethernet adapter, the POE pass-thru was always turned on on the lower left port. I assume the port is working fine since I can see it in the switch table but I'm hesitant to plug anything else into it
Can someone help me look into these two problems? After that it looks like it should be fully functional
