Start Hue Sync and room lights from one Google command

A single voice phrase can start a nice living-room mode, but it helps to split the job into pieces. Google Home is good at receiving the voice command and starting supported media actions. Hue is the right place to define the lighting scene or sync behavior. The reliable automation is usually a routine that calls known scenes rather than a vague instruction to make everything sync.

Build the routine from stable pieces

1. Confirm the soundbar, Spotify account, Hue lights, and Hue Sync setup all work manually before combining them.
2. Create the lighting state in Hue first: entertainment lights in sync mode if supported, and any ordinary lamps set to the brightness you want.
3. In Google Home, create a routine with the phrase you want to say and add the supported media and lighting actions available to your linked devices.
4. If Google cannot directly trigger the Hue Sync state, use the closest supported scene or a two-step routine: start the scene, then start sync from Hue or the Sync Box control.
5. Keep one manual fallback scene for when HDMI detection, music playback, or voice recognition misses a step.

Return to normal after the session

Entertainment lighting should not become the room's default state. If Rhythm manages the same room, use it to bring lights back to the everyday Day or Sleep feel after music or TV sync ends. Let Hue handle the specialized sync effect; let Rhythm preserve the comfortable baseline.
