If you are still experiencing issues with your Nanoleaf 4D, try these steps:
Power cycle your Nanoleaf 4D devices by unplugging them from power and then plugging them back in.
Try toggling your Wi-Fi off and back on, restarting the app you’re using to control your lights, or restarting your device.
Check a Switch
Make sure that your lights weren’t turned off by a physical switch such as on a power bar as this would make them powered down and unresponsive.
Reset the device by pressing the Power and Colour Scene button on the Controller together for at least 10s, while it is still powered on.
If you’ve performed all of these steps and your issue still persists, please reach out to our support team for further assistance.
