The technology behind smart home devices is often based on IoT (Internet of Things), which connects various devices through the internet for enhanced functionality and automation. Smart home devices, like thermostats, lights, and security systems, use sensors and actuators to monitor and control environments. Through centralized hubs and apps, users can manage these devices remotely. IoT protocols allow seamless communication and data exchange among devices, ensuring user convenience and energy efficiency, thus transforming how individuals interact with their living spaces.
