Lots of "things" (devices) can be connected to the internet. They can be home energy monitoring or security. It is felt that more and more devices, doing more and more "things" will be available in the future.
Here's a Wikipedia explanation of Building and Home Automation
Building and home automation
IoT devices can be used to monitor and control the mechanical, electrical and electronic systems used in various types of buildings (e.g., public and private, industrial, institutions, or residential) in home automation and building automation systems. In this context, three main areas are being covered in literature:
- The integration of the internet with building energy management systems in order to create energy efficient and IOT driven “smart buildings”.
- The possible means of real-time monitoring for reducing energy consumption and monitoring occupant behaviors.
- The integration of smart devices in the built environment and how they might be used in future applications.
