5. Software requirement

This software will be based on the MTK platform. It runs on the OpenWrt system. 

It supports the following features:

  • Wi-Fi 
  • Zigbee3.0
  • OTA
  • MQTT

5.1 Defines

5.1.1 Boot up

When inserting the power, The green and yellow Led are lightings, the Yellow LED is going out and the green LED is blinking, the green led is lighting, and 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 operation of the Zigbee and z-wave. When the gateway communicate with sensor, the led will be blink.  If let the gateway goes into pairing mode, the led will be blinking.
  • Red LED: it’s used to indicate the gateway connects with the cloud, if the gateway connects successfully, the Red LED goes out, and failed is lighting.
