This is a Matter-certied device. You can integrate it into any Matter ecosystem you prefer for easy control.
Before You Start

• A Matter-supported controller and smart home app of the same ecosystem are required. For optimal performance, please update them
to the latest version.
• The Matter setup code on the device is only applicable for the initial ecosystem. To add it to a new ecosystem, you will need to generate a
new setup code from a smart home app of an already-established ecosystem in your home.
• Take a photo of the Matter setup code for backup.
• Bluetooth will be turned o 15 minutes after the device is powered up. Restart your device to re-enter setup mode.
How to Set Up

1. Turn on Bluetooth on your phone.
2. Open the smart home app, then scan the Matter QR code or enter the provided numeric setup code (usually can be found on your
device).
3. Follow the instructions in the app to complete setup.
Failed to Set Up?
• Try to connect your phone to a stable 2.4 GHz Wi-Fi network with internet access instead of a 5 GHz network.
• Restart your device, controller or phone.
