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.
Short answer
“No Thread networks were found” usually means the app cannot see an active Thread border router on the same account and local network, or the device you bought is not acting as the Thread border router you expected. Matter-over-Thread accessories need both a Matter controller and a Thread border router; marketing names can make that distinction easy to miss.
What to verify
- Confirm the exact model and generation supports Thread border-router behavior, not only Zigbee or smart-home hub features.
- Update the speaker, hub, or display firmware before pairing.
- Use the same account and home in the controller app.
- Keep the phone, controller, and accessory close together for first pairing.
- If the accessory is a button for lighting control, verify your target lights are already in the same ecosystem or automation platform.
Using Rhythm for this setup
Rhythm LightHub is for compatible Matter lighting control, not a magic replacement for every Thread border router in every ecosystem. If the light or switch is Matter over Thread, make sure the Thread infrastructure is healthy before building lighting automations around it.
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.
