Abstract: Disclosed is a Wi-Fi enabled wide area automation system. The system includes an application installed in a handheld wireless communication device for wireless controlling of the at least one appliance by accessing a specific preset hypertext markup language (HTML) page. A microcontroller server communicates with the application to control the at least one appliance. The microcontroller server is configured to operate in a web server mode using TCP/IP stack. A Wi-Fi router connected with the microcontroller server using a wireless local area network (WLAN) enables the microcontroller server to communicate with the handheld wireless communication device. A relay controls the at least one appliance based on a signal from the microcontroller server. A liquid-crystal display (LCD) displays a plurality of statuses of the microcontroller server.
