Smart home is a system that controls electrical equipment remotely via WLAN and Internet. The Smart Home system was created using Raspberry Pi as a data processor, Android Smartphone as a user interface, the relay module as electronic appliance controller, Wi-Fi dongle as a communication medium and a router for port forwarding. In addition, the system is equipped with a security system that can be used to monitor the situation around the home via a webcam as IP Camera, PIR sensor for motion detection and GSM modem for sending SMS and telephone. The test results showed that the Smart Home system can work properly to control four loads at once via the internet or through the media WLAN. The features of the security system works well to monitor the situation through the application interface based on Android and warnings in the form of SMS and telephone numbers sent to the user when the PIR sensor detects movement. Therefore, the smart home system is stable, safe, reliable, easy to use, thus, contributing to efficient energy usage in order to conserve precious natural resources by reducing electrical energy consumption.
