Every home appliances comes with a default way of switching in a traditional way to turn on and turn off by touching the switch. Sometimes, it is not comfortable for the elderly, or even the young and busy individuals especially when the frequent switching operation is required. Thus, an easier method of switching is needed to replace the manual switching method using an advanced switching method for electronic home appliance through the use of android application via our mobile devices. The research aimed to design and construct a prototype of a home automation system for electronic appliances, which gives the user complete control over all electrical appliances of the home using Wi-Fi (Wireless Fidelity). The system is a Wi-Fi based home automation system which has two main parts hardware and software. The system is developed using NodeMCU modules which receives, sends data and communicates with other components via Wi-Fi. The software development methodology used in the work can be described as a mix of incremental development model and the evolutionary prototyping approach. The Incremental model helps to divide the segment into small parts (e.g., functionality and features) each having objectives and constraint that was determined before the development. By using the evolutionary prototyping approach helps to improve the system by adding new features and functionalities. The programming language used for the system development is C++ to enable the NOdeMCU. The system is capable of switching on/off electrical appliances such as light bulb, fan, socket, AC-Air Conditioner automatically and can as well determine the time for power usage in the home through the mobile application thereby reducing cost and better safety for the equipment.
