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
The gateway can be upgradeable over the network.
5.8 MQTT
The gateway support the MQTT protocol to connect the cloud.
