This document describes the implementation of the Connected Home Gateway for the Internet of Things (IoT) and its controller implemented in a Smart device (tablet) running Android OS.


The gateway is intended to serve as a communication bridge between WiFi/Ethernet and ZigBee Protocol, making every ZigBee-enabled device accessible and controllable from any smart device with Wi-Fi capabilities such as a smart phone or tablet. This will remove the need of having a ZigBee transceiver in every mobile device attempting to control the house appliances. In general, users will be able to:


  • Remote control of Home Appliances using ZigBee protocol
  • Any WiFi-enabled device could control the appliances without a ZigBee transceiver
  • Achieve bi-directional communication between users and appliances

 

Real system implementation would require a powerful MCU to manage all WiFi/Ethernet communication and a second MCU to manage all ZigBee communications. The Kinetis K60 and KW24 were selected among the different options available.
