The accelerating convergence of wireless communication technologies and miniaturized sensor hardware has substantially broadened the scope of intelligent residential systems. This paper presents a systematic review of five peer-reviewed Indian research publications, each examining a distinct dimension of Internet of Things (IoT)-enabled home automation. The studies collectively address control architectures, embedded hardware selection, energy management strategies, real-time hazard detection, and multi-modal user interaction mechanisms. Through structured comparative analysis, recurring themes, prevailing technical constraints, and prospective research trajectories are identified. The review affirms that IoT- driven smart home systems have demonstrated consistent utility in advancing residential convenience, curtailing energy expenditure, and facilitating remote appliance governance, while also highlighting that cybersecurity robustness and large-scale deployment scalability remain underexplored frontiers requiring sustained investigative attention.
