Chihiros WRGB II Slim problem

[roel]

Hi all,


Since I came back from a short holiday, my WRGB II Slim lamp is no longer functioning normally.

• The light does not turn on anymore.
• When unplugging and plugging it back in, nothing happens.
• The indicator light on the adapter is green.
• I measured the output with a multimeter, and the voltage going in to the led controller is normal.
• I removed the device from the app, but now it cannot be found anymore when I try to add it again.
• I rebooted my iPhone 16 Pro (iOS 26) and even reinstalled the app.
• I also tried with an older Android phone which i never used the light with (or the app), but it is not showing up there either.
• It does not appear in a BLE scanner either.

Technical summary:

• Power adapter output = OK
• Lamp not turning on
• Controller not visible in app or BLE scanner
  → Suspected controller failure or internal lamp defect

Does anyone know what else I could try, or is this a sign that the controller/lamp needs replacement?


Thanks in advance!

Plug in the light, open bluetooth.
Totally close the app My Chihiros from phone backend. Download an app nRF Connect to scan all the devices, take screenshots of all the devices it finds on Scanner page.
