Once your gateway is configured, you can start adding ZigBee and Bluetooth-compatible smart devices to your network via the Smart Life/Tuya App. Refer to the individual device manuals for specific pairing instructions, which usually involve putting the device into pairing mode and then discovering it through the app.

The Smart Life/Tuya App allows you to control all connected devices remotely, create groups, and set up automation scenarios. You can monitor sensors, control lights, thermostats, and other appliances from anywhere with an internet connection.
- Group Control: Combine multiple devices into groups for simultaneous control (e.g., turn off all living room lights).

If you need to reset the gateway's network configuration (e.g., changing Wi-Fi networks or troubleshooting connection issues):
- Ensure the gateway is powered on.
- Press and hold the reset button until the red light is solid and the green light flashes. This indicates the gateway has reset its network settings.
- You can then proceed with the "Gateway Network Configuration" steps (Section 4.2) to reconfigure it.
8. User Tips
- For optimal performance, place the gateway in a central location within your home, away from large metal objects or other sources of interference.
- Ensure your Wi-Fi network is stable and operating on the 2.4GHz band during setup and operation.
