FWIW I was struggling to add these plugs via Matter, but eventually this is what worked for me (might help others):
Run Matter server in docker container
Added Matter integration in HA
Plug in KP125M (factory reset if needed)
Switch iPhone to 2.4Ghz network
Add Matter device via HA app, scan QR code, plug should be added fairly quickly
Plug automatically recognized in Kasa app (for other features)
I have multicast DNS still enabled with a Unifi network. No energy monitoring in HA of course, but should be enabled in the future whenever Matter spec is updated.
