This guide answers a smart-lighting or Matter lighting question and translates
it into a practical checklist for Rhythm users. If you are pairing compatible
Matter lights, the Rhythm Lighting LightHub can commission them from the
Rhythm app: choose Add Device, select Matter, then scan the
QR code or paste the MT: payload / 11-digit setup code. The
LightHub performs the commissioning handshake and keeps the device on your
Matter fabric.
Separate detection from the off action
A light that turns off while someone is still in the room is usually not a light problem. It is an automation timing problem: the sensor briefly reports no motion or no occupancy, and the off rule acts before the next detection event arrives.
- Watch the sensor history for motion, occupancy, illuminance, and battery. Look for short gaps where the state changes to clear.
- Add a delay to the off automation and re-check the sensor state at the end of the delay before turning lights off.
- Use occupancy if the sensor exposes it reliably; otherwise use a conservative no-motion timeout for rooms where people sit still.
- Make sure there is not a second automation, scene, or vendor-app rule also turning the same light off.
- Place the sensor so small movements happen across its field of view, not directly toward or away from it.
Keep adaptive lighting separate
Presence should decide whether a room is active. Adaptive lighting should decide what the active room looks like. In Rhythm, that means the room can keep following its brightness and color-temperature curve while HomeKit, Home Assistant, or a sensor automation handles occupancy-based on and off.
For Matter lighting rooms
If the controlled lights are Matter-compatible, commission them through the Rhythm app and LightHub with the Matter QR code or setup code while all devices are on the same local network. Once the lights are stable in Rhythm, troubleshoot sensor automations separately so pairing issues and occupancy logic do not get mixed together.
Pairing with Rhythm
For Matter lights and bulbs, the LightHub is the bridge between the app and the device during pairing. Keep the LightHub, phone, and device on the same local network, keep Bluetooth enabled when the device requires BLE commissioning, and make sure the setup code has not expired or already been used by another fabric. Once paired, the LightHub can control the device locally as part of your Rhythm setup.
