If a lamp app hides or removes a daylight-sync feature, you can still build the behavior in Rhythm when the light is available through a supported hub or Matter-compatible control path. The goal is simple: let the room follow a predictable brightness and color-temperature curve instead of depending on a vendor-only mode.
Confirm the light can be controlled
- Connect the light through Hue, Home Assistant, or a compatible Matter path that Rhythm can see.
- If it is a Matter-compatible light, add it from the Rhythm app with the LightHub by scanning the Matter QR code or entering the setup code while your phone, LightHub, and light are on the same local network.
- Open the room in Rhythm and confirm the light responds to brightness changes before tuning the curve.
Set your home and solar timing
- Make sure your home location is set so Rhythm can calculate local sunrise, sunset, solar noon, and solar midnight.
- Open the Day profile for the room or home.
- Choose a warm, dim low end for morning and evening, then set the daytime brightness and color-temperature ceiling that feels comfortable.
Preview and refine
Use the time simulator if it is available in your plan, or check the room at morning, midday, and evening. Adjust the brightness range first, then tune color temperature. If the lamp only exposes RGB and not real kelvin control, use the closest warm and cool values the integration supports.
Avoid double automation
Disable duplicate daylight, wake, sleep, or scene schedules in the vendor app for that same room. Rhythm should be the source of truth for the daily curve; the vendor app can remain available for firmware updates and special effects.
