Hue's page for the Sync Box 8K lists compatibility with third party systems: Alexa, Google Home, Apple Home, IFTTT, Matter, Samsung SmartThings and Sonos. The Sync Box works through the Hue Bridge, and Hue's Matter guide explains that with a Bridge you go to Settings, Smart Home in the Hue app, choose your platform and follow the linking steps; the Bridge route supports all Hue products and advanced features such as entertainment sync.
The checks in more detail
Once linked, the Sync Box can appear in Apple Home and other platforms so you can start and stop sync and pick modes from them, subject to what each platform exposes. Apple Home needs a home hub, though iOS 18 and up can pair Matter devices without one. If the box does not appear in a platform, check it is set up in the Hue app, the Bridge is linked and updated and refresh the platform.
Multi-admin lets you share to several platforms by generating a new setup code in the original app. Keep the Hue app, Bridge and box firmware up to date. If a platform shows the box unresponsive, restart the box and check wifi. Note which platform is the main controller so commands do not conflict. A new setup code is needed each time you add a platform. Read the Matter guide once. A platform that shows the box but not every mode is normal, so use the Hue app for detailed settings and the platform for simple start and stop. Hue says the Bridge route supports advanced features like entertainment sync, so keep the box on the Bridge and share to other platforms rather than trying to pair it directly.
