Apple AirPlay and HomeKit support is available on select 4K Roku streaming devices, including the Roku Ultra, Roku Streambar, Roku Smart Soundbar, Roku Streaming Stick+, and Roku Premiere.
Apple AirPlay support allows you to stream and share content directly from your iPhone, iPad, or Mac to your supported Roku device. With HomeKit, you can control your Roku device with your voice or by using the Home app and Siri on an iPhone, iPad, Mac, Apple Watch, or HomePod.
Also, Roku TV models are expected to receive Roku OS 9.4, which enables Apple AirPlay 2 and HomeKit for select 4K Roku TVs, in phases over the coming weeks. You’ll be able to mirror what’s on your Apple device’s display to your TV screen and control your TV’s power, volume, and switch inputs.
