Smart devices, such as thermostats, provide advanced control over a home's heating and cooling system. Here are some features that help thermostats work in an IoT ecosystem:

Sensors 

• Detect factors such as temperature and humidity

• Collect data on indoor environment and user preferences to optimize operations 

Communication Technologies

• Connect to the Internet (e.g. Wi-Fi) to communicate with other devices, such as smart home hubs or mobile apps

Cloud Integration

• Send collected data to the cloud, where it can analyze user preferences, schedules, and environmental conditions

• Use cloud insights to control when the thermostat should preheat or cool the home
