5.1 Defines

5.1.1 Boot up

When insert the power , The green and yellow Led are lighting, the Yellow LED is go out and the green LED is

blink, the green led is lighting, the gateway boot up successfully.

5.1.2 Reset

Keep pressing the button for 5s. All matching information is eliminated.

5.1.3 Indicator LED

  • Green LED: it’s used to indicate system startup

  • Yellow LED: it’s used to indicate the operating the Zigbee and z-wave. When the gateway communicate with

        sensor, the led will be blink. If let the gateway go into pairing mode, the led will be blink.

  • Red LED: it’s used to indicate gateway connect with cloud, if the gateway connect with successfully, the Red

        LED is go out, failed is lighting.

5.2 Wi-Fi Configuration

The Wi-Fi support the AP mode and client mode. It can be switched.

The name of AP: xxxxxxx

Pass word: xxxxxxx

5.3 Zigbee Configuration

The ZigBee stack is version 3.0, it can support ZHA, Greenpower, ZLL,etc. It support most cluster of ZigBee


Like door sensor, leakage sensor, Motion sensor, Tem&Hum sensor, smart plug, Smart lamp, smoke sensor,

curtain etc.

It can used web or command to add the device.

5.4 OTA

The gateway can be upgradeable over the network.

5.5 MQTT

The gateway supports the MQTT protocol to connect the cloud.

6. Application


1) Smart Gateway collects information about Beacon nearby, including RSSI, MAC, etc., once per second.

2) Smart Gateway send the Beacon information to Cloud via Wi-Fi .

3) Smart Gateway support the TCP/IP, UDP protocol, and can support the MQTT, LWM2M protocol.

4) Smart Gateway support connect ZigBee and z-wave devices.
