Smart TV HomeKit, Home App Support
At CES 2019, it was announced that HomeKit and AirPlay 2 support is coming to a slew of third-party smart TVs. In iOS 12.2 betas, it seems like Apple is already baking-in support for those third-party platforms. That includes new HomeKit infrastructure that will allow users to add their smart TVs to their Home app.
In a related change, there is now an option for allowing “Speaker & TV Access” within the Home app settings (previously, the feature only referred to speakers).
