Therefore, reducing the energy wastage in the household environment is essential. Researchers from all around the world are working to develop IoT-based solutions to reduce energy wastage, but there are certain challenges in adapting them to the local context as those techniques were developed for foreign domestic usage. As a result, it is crucial to come up with IoT-based solutions which are appropriate for the local environment to assist the reduction. Therefore, this article examines the importance and feasibility of adopting IoT-based electrical and electronic device control systems for household use in Sri Lankan environments. Further, a mobile application was developed to monitor and control the system, which was installed for a residential building after an analysis of the domestic requirements. This system may simply fix into an existing building, making it a cost-effective application for reducing energy wastage in developing countries.enElectrical and Electronic Appliance Management SystemEnergy WastageInternet of Things (IoTSmart BuildingArticlehttps://doi.org/10.31705/WCS.2023.13
