| Summary: | <p align="justify">The latest renewable energy source, such as solar cells and fuel cells have a direct current (DC) electrical output. The energy storage technology such as battery also has a DC output. Thus, it is reasonable for a house with renewable energy to use DC grid eletrical system as its power distribution. The concept of a house with stand-alone energy generation and DC electrical grid has been proved to yield a better energy efficiency than that with alternating current (AC) grid system. This research aims to develop a smart system which has the ability to monitor and automatically control various appliances on such a DC-grid home system. <br />
<br />
This smart system has 4 components, consists of internal network, the controller, automation application on server and user interface. The controller is an Arduino-based embedded system, while the server is built on Raspberry Pi or Personal Computer (PC). For the communication between the controller and the server, a Power over USB (PoU) as transmission medium is developed. PoU can transfer electric power and digital data simultaneously on a single Unshielded Twisted Pair (UTP) cable. In the server, a Java-based application runs monitoring and control program that communicates with all of the controllers using Modbus protocol. Users can access automation application on server via Wi-Fi network by using smartphone with WebSocket protocol compatible browser. <br />
<br />
This system, which use PoU technology and Modbus protocol has been undergone performance testing. At distance 20 meter, the electric power distribution has 0.417% drop voltage and maximum data transfer at 7686 bytes per second. Meanwhile, the smart home controller also successfully carry out its functionality on on-off remote switching testing and schedule-based automatic control of home appliances. <br />
