Rhythm talks to Hue through your existing Hue Bridge over the local network. You don't need to re-pair the bulbs — they keep their Hue groupings and stay reachable from the Hue app.
What you need
- A Hue Bridge (v2, the square one) on the same network as the LightHub
- Physical access to the bridge for one button press
Pairing
- In the app, go to
Add device → Hue Bridge. - Press the big round button on top of your Hue Bridge within 30 seconds.
- Wait — every bulb behind the bridge appears in the device list.
Notes
Coexistence
The Hue app keeps working. Changes made there sync back to Rhythm within
a second or two.
