ANALYSIS OF ELECTRICITY CONSUMPTION OF IOT DEVICES USED IN HOME AUTOMATION: A CASE STUDY FOR REDUCING ELECTRICITY CONSUMPTION

Abstract

Home automation has been growing in recent years and was boosted by the COVID-19 pandemic. With social isolation measures in place, people needed to spend more time at home, leading to the need to automate routine activities. A study conducted by IDC Brazil (International Data Corporation) shows that the home automation market grew by 21% in 2021. In Brazil, the expectation is that it will grow by about 30% in the coming years. According to the study, what is driving this increase is a greater interest in Internet of Things (IoT) technologies. Among the main devices are those focused on security, voice assistants, smart switches, and smart thermostats. Therefore, this work aims to investigate the electrical energy consumption of these devices, commonly found in home automation, as well as to conduct a study of the economic feasibility of home automation through its application in reducing residential electricity consumption. With the data from the devices' consumption measurements, the equipment will be placed in a simulation platform to perform an economic analysis of the electricity bill, with and without automation. Finally, through the case study, it is possible to confirm that the proper use of automation can result in a significant reduction in the electricity bill.
