Hue's Sync Box 8K page lists voice assistants, Amazon Alexa and Google Assistant, with a Hue Bridge required, and compatibility with Apple Home, Matter, SmartThings and Sonos. Link the platform in the Hue app under Settings, Smart Home, choose Apple, Google or Alexa and follow the linking steps as Hue's Matter guide explains. Once linked you can ask a voice assistant to start or stop sync, change the sync mode or intensity and control the lights the box drives.
The checks in more detail
If a command does not work, check the box and Bridge are online, that the box appears in the platform and that its name is simple. Rediscover devices after renaming. When Alexa or Google cannot reach the box, remove the skill link and set it up again. The box also has an IR receiver and CEC, so a TV remote can control it.
If voice starts sync but the lights do not respond, the entertainment area or Zigbee link may be the fault, not the voice link. Keep the Hue app, box firmware and controller updated. Apple Home works best with a home hub, though iOS 18 and later can pair Matter devices without one. Voice does not change the HDMI chain or picture settings. Test with a single light first before you try to start sync by voice. Give each device a short name that no other device shares. Practise a few commands.
If voice starts sync but the picture blanks, the box may be switching inputs, so check CEC before blaming the assistant. Hue lists Alexa and Google voice support only with a Bridge, so if commands fail and no Bridge is present, that is the reason and not a fault.
