Which of the following is a common application of IoT in smart homes?

Digital signage
Smart thermostat systems
High-performance computing
Data storage solutions

The correct answer is: Smart thermostat systems

Smart thermostat systems are a prominent application of the Internet of Things (IoT) within smart homes due to their ability to enhance energy efficiency and provide convenience to homeowners. These systems allow users to remotely monitor and control their home heating and cooling systems via mobile applications or smart home devices, leading to optimal energy usage based on the household's schedule. Additionally, smart thermostats can learn user preferences and make automatic adjustments, thereby saving energy and costs over time. In contrast, digital signage is typically utilized in advertising or information dissemination in public spaces rather than within residential environments. High-performance computing focuses on advanced computing power for tasks like research and simulations, which does not align with the typical needs of a smart home. Data storage solutions relate to managing or saving electronic data, which, while important, does not directly represent an IoT application in home automation. Thus, smart thermostat systems stand out as a direct application exemplifying the integration of IoT technology in enhancing the smart home experience.
