such as Wi-Fi, Zigbee3.0, OTA, and MQTT.

5.1 Definition
5.1.1. Boot Up

Upon power insertion, both the green and yellow LEDs light up. Once the yellow LED turns off and the green LED starts blinking, and then remains lit, the gateway has successfully booted up.

5.1.2. Reset

Press and hold the button for 10 seconds to perform a reset function. This will erase all matched information.

5.1.3. LED Indicators

Green LED: Indicates system startup.

Yellow LED: Signals operation of Zigbee. When the gateway communicates with a sensor, this LED blinks. If the gateway enters pairing mode, the LED will blink as well.

Red LED: Used to indicate connectivity with the cloud. If the gateway connects successfully, the Red LED turns off. If the connection fails, it remains lit.

5.1.4. Wi-Fi Configuration

The Wi-Fi supports both AP and client modes, which can be switched as needed. The name of the AP: xxxxxxx. Password: xxxxxxx.

5.1.5. Zigbee Configuration

The Zigbee stack, version 3.0, supports ZHA, GreenPower, ZLL, and more. It is compatible with most clusters of ZigBee devices, such as door sensors, leak sensors, motion sensors, temperature and humidity sensors, smart plugs, smart lamps, smoke sensors, curtains, and so on. Devices can be added via the web or command.

5.1.6. BLE Configuration

The gateway supports iBeacon, Eddystone, BLE sensors, and the SIG mesh function.

5.1.7. OTA

The gateway’s firmware can be upgraded over the network.

5.1.8. MQTT

The gateway supports the MQTT protocol for integration.
