Can't get Matter devices to work on Homekit - going insane!
Hi everyone! I have a HomeKit based home with a Ubiquiti backbone: ISP ONT -> UX7 -> USW Ultra. I consider myself an amateur but god have I tried everything to make it work. Your help would be much, much appreciated.
Pretty much the title - regular stuff connects fine, Matter based devices get an instant "pairing failed" error. I have Aqara hardware: a G5 camera hub (PoE version, which is also a Matter hub) and a Door/window sensor.
As soon as I try to pair the camera hub via Matter to Apple Home in the Aqara app it fails instantly, per the screenshots.
My current VLAN setup is main network for my devices (that's where the Apple TV is) and the IoT VLAN (where the G5 camera is). I have IPv6 enabled, VLANs can talk to each other.
IMHO the systems can see each other as per the 3rd screenshot (Home app can see the hub) but I get the same error in the screenshot, just coming from the Home app and not the Aqara app.
Everything is updated to the latest version; Apple TV is on tvOS 26 not 27.
I'm hoping some of you have the same Ubiquiti/Homekit/Aqara Matter devices and hope to tell me wth am I doing wrong! Let me know if you need additional info to help me on this and thanks so much in advance!
