  • MQTT
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 is used to indicate system startup
  • Yellow LED: it is 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 is 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

The Zigbee stack is version 3.0, it can support ZHA, Greenpower, ZLL, ZSE etc.

It support most cluster of Zigbee devices. 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 Bluetooth Configuration
The Bluetooth is core 5.0, it supports BLE 5. It can used web or command to add the device.
5.5 Z-Wave Configuration
Z-Wave is a standard module, it supports most cluster of Z-Wave devices. It can used web or command to add the device.
5.6 LTE Configuration

The gateway power on , the LTE will set up , and check if there is a sim card, then scan the network and join it.

It can used the web or command to change the APN to adapt to different countries.

5.7 OTA

6.2 AP-02 Beacons for Indoor guidance and location
DM 20220629170549 017
Exemplary deployment of a beacon infrastructure
The beacon attached to the asset to be tracked sends BLE signals to Smart Gateway that are installed in the building. The Gateway processes the provided data and sends it via Wi-Fi, Ethernet to Server. Here, the position is displayed on a map and motion statistics can be retrieved.
6.3 AP-03 Smart Home IoT
DM 20220629170549 018
Exemplary deployment of a beacon infrastructure

The Smart Gateway as the brain of the smart home connects wirelessly with a wide range of smart devices and make them work together.

  • Control lights, electronics, and small appliances from anywhere.
  • Set devices to turn on and off at different times of day.
  • Receive alerts when there’s unexpected activity in your home.
  • Set connected lights to turn on and off as people come and go.
  • Monitor moisture and temperature.
