Introduction

Smart homes integrate advanced automation systems to provide residents with sophisticated control over their living environment. These systems enhance convenience, security, energy efficiency, and accessibility by leveraging interconnected devices, sensors, and artificial intelligence.

Historical Development

Early Concepts (1970s–1990s)

  • 1975: X10 protocol introduced, enabling remote control of home devices via powerline communication.
  • 1980s: Emergence of “wired homes” with centralized control panels for lighting and security.
  • 1990s: Proliferation of personal computers and the Internet led to the first networked home automation solutions.

21st Century Evolution

  • 2000s: Wireless protocols (Zigbee, Z-Wave, Wi-Fi) replaced wired systems, enhancing flexibility.
  • 2010s: Integration with smartphones and cloud computing allowed remote monitoring and control.
  • 2020s: AI-driven automation, voice assistants (e.g., Alexa, Google Assistant), and IoT ecosystems became mainstream.
