Technological developments are currently growing rapidly, as evidenced by the many technologies based on the Internet of Things, such as the smart home, a technology which has been developed a lot, including control and security systems in a house. This system was developed to control lights and electronic devices that are integrated into the internet of things with the aim of saving electricity and safety factors that might cause an electrical short due to negligence and forgetting to turn it off. This study aims to design a smart home prototype based on the Internet of Things that can be controlled by voice commands, using the ESP8266 NodeMCU device as the control center. This prototype consists of several components such as lights, fans, and electric door locks. Communication between devices is regulated through a WIFI network that allows users to give voice commands via connected smartphone devices. The ESP8266 MCU node is the brain of the system that processes and receives voice commands so that when the voice command has been received by the system, the smart home will react according to the voice command.
