This page assumes you have a LightHub Zero and at least one compatible bulb. If you don't have hardware yet, see Requirements.
Before you start
- An iPhone running iOS 17 or later
- 2.4 GHz Wi-Fi available at the install location
- A power outlet within reach of the LightHub
1. Install the app
Download Rhythm from the App Store and open it. You'll be asked to grant local network and Bluetooth permissions — both are required to find the hub.
2. Pair the LightHub
Plug in the LightHub. The status light will pulse amber while it's
looking for the app. In Rhythm, tap Add device → LightHub and
follow the on-screen prompts.
Status light:
pulsing amber → looking for app
solid amber → paired, waiting for bulbs
solid white → online and running scenes 3. Add your bulbs
Once the hub is online, head to Devices → Add bulb and pick
the integration that matches what you own. Each integration has its own
page in the sidebar with the specific gotchas.
4. Run your first scene
Tap Scenes → Circadian default. This enables the built-in
sun-tracking schedule. Within a few seconds your bulbs should shift to
match the current time of day.
