The technology that allows for the remote control of devices in a smart home is primarily based on Internet of Things (IoT) principles. IoT technology connects household devices to the internet, enabling communication and control through mobile apps or voice assistants. This setup allows users to monitor and manage appliances, lighting, heating, and security systems from anywhere. Protocols such as Zigbee and Z-Wave facilitate communication between devices, while cloud services provide the infrastructure for operational management, enhancing convenience and energy efficiency in modern homes.
