How can I reset my light to factory settings?
Begin with the bulb turned on. Turn the bulb off and back on six times in a row, with an interval between each change of power state between 0.5 and 1.5 seconds. The light will either cycle through red, green, blue, and white, or blink twice, both of which indicate a successful reset. -
How do I add my Linkind light to a Matter ecosystem?
In your Matter ecosystem of choice, select the option to add a new device and then add your Linkind light by scanning the QR code found on the light or by entering the 11-digit code manually. -
What should I do if I can't scan the QR code on the device?
If the QR code on the device can not be scanned, you can scan the same QR code from within the instruction manual instead. -
What should I do if my light fails to connect to Apple Home?
Ensure the device running the Apple Home app is connected to a 2.4 GHz Wi-Fi network and the corresponding hub is connected to the same network. If the issue persists, try rebooting the hub, app, and mobile device. -
What should I do if my light shows as offline?
Try controlling the device to see if it responds. If it doesn’t, turn the device off and back on. Allow up to 2 minutes for it to reconnect to the network and then check its status again. -

What should I do if my light cannot be found?
If it is your first time connecting to this light, or if it has been reset to factory settings, turn the light off and back on. Try connecting within 15 minutes of the light being powered on. If the light has previously been configured, or connected with other hubs or apps, ensure all devices are connected to the same network and that pairing mode has been activated. -
What should I do if the device name is different from what I set?
Avoid restarting the device during the setup process. After adding the device, wait for the data to synchronize, or manually refresh the app to see the updated name. -
