The technology powering smart home devices primarily revolves around the Internet of Things (IoT). IoT enables interconnected devices to communicate and share data over the internet, allowing users to control appliances, lighting, security systems, and more remotely. This connectivity is facilitated by protocols like Zigbee, Z-Wave, and Wi-Fi, which ensure seamless integration among devices from various manufacturers. Additionally, smart home ecosystems often incorporate machine learning algorithms to adapt to user preferences, ultimately enhancing convenience, energy efficiency, and overall home management.
