IoT device monitoring involves the continuous supervision and analysis of data generated by interconnected devices to ensure optimal performance and functionality. By monitoring key metrics such as temperature, humidity, and energy consumption in real-time, organizations can detect deviations from normal operating conditions and take corrective actions promptly. This proactive approach helps prevent downtime, improve operational efficiency, and reduce maintenance costs associated with IoT deployments. IoT device monitoring is integral to achieving seamless connectivity and reliable performance across smart homes, industrial IoT, and smart city infrastructures.
