In this paper, a Home Automation system based on IoT that employs the integration of cloud networking, microcontroller, smartphone and wireless communication, to provide the user with remote control of various lights, fans, and appliances within their home using their smartphone and store data onto the cloud is presented. It also has safety and security features. This system is designed to be low cost, easy to install, compatible with existing home appliances and expandable allowing a variety of devices to be controlled. We tackle the problem of high cost, use of proprietary wireless technology by various companies which are incompatible with each other, incompatibility with existing home system and difficulty of use by designing an IoT system which is based on low-cost open source technology.
