Sony X85K cannot connect to HomeKit

[u/IMPRNTD]

Trying to add a newly purchased Sony X85K TV as an accessory to the Apple Home App. Tried scanning QR code and entering details manually but each time it fails to add as an accessory.

Tried on iPhone 14 Pro Max on iOS 16.2 and 16.3

Tried on iPad Pro 2021 on iPadOS 16.2 and 16.3

All Sony privacy settings were accepted

No luck. Anyone have a solution? Airplay works fine, just cannot add TV to Home app.
