Open official FAQ ↗Before opening the FAQ
Start by matching the app to the controller, not the other way round: the three apps above target different controller families, and a controller only answers the app it was built for. The product listing or the QR code in the packaging names the right one. The FAQ links open the developer's official documentation and automatically follow the language you are reading this site in.
Check the phone before blaming the light
Most "app cannot find the controller" reports are resolved on the phone. Bluetooth must be on, and on Android the app also needs the Nearby Devices permission (called Location on older Android versions) before the system lets it scan — a denied permission looks exactly like a missing controller. A Bluetooth controller usually holds one connection at a time, so close the app on any other phone that has paired with it before scanning again. For Wi-Fi devices, join the 2.4 GHz network during setup; many controllers cannot see a 5 GHz-only network. And confirm the controller is actually powered — in a car, that usually means the ignition or accessory (ACC) position, not just a parked vehicle.
When it is hardware, not the app
If the controller still never appears after those checks, the fault has probably left the software, and the site's repair guides continue from exactly this point: vehicle ambient controllers that never show up in a scan, smart lights that keep dropping offline, voice control failing while the app still works, and measuring a controller's outputs to decide whether the controller or the strip has failed.
