Smart home devices utilize various technologies like IoT (Internet of Things), wireless communication protocols (such as Zigbee, Z-Wave, and Wi-Fi), and voice recognition systems. These devices include smart speakers, thermostats, security cameras, and lighting systems, which are interconnected to enhance home automation. IoT allows devices to communicate with each other and with users’ smartphones or central hubs for remote control and monitoring. Voice assistants like Amazon Alexa or Google Assistant enable users to interact with their smart homes effortlessly. Together, these technologies contribute to greater convenience, energy efficiency, and security.
