What is the role of IoT devices in a central hub and control system?

IoT devices play a crucial role in a central hub and control system primarily by reporting their state and configuration. These devices are equipped with sensors and actuators that collect data about their environment and operations. This data may include information on temperature, humidity, motion, and other specific metrics relevant to their function.

By sharing this state information with a central hub, IoT devices enable real-time monitoring and control of the system. The hub processes these reports, allowing users to make informed decisions, automate actions, or adjust settings based on the current conditions detected by the IoT devices. This continuous flow of information is vital for maintaining an efficient and responsive IoT ecosystem.

In contrast, other choices reflect different functionalities or limitations of IoT devices. For instance, while some IoT devices do communicate without sensors, their primary purpose in this context relates to data reporting. The option regarding the primary storage unit misrepresents the role of IoT devices, as they typically do not function as storage but rather as data collectors. Finally, the statement about connecting only to LANs doesn't capture the broader range of connectivity options available to IoT devices, which can include WANs, cellular networks, and various other protocols. Thus, reporting state and configuration clearly stands out
