The Design of Application for Smart Home Base on LoRa

Applicated of LoRa technology itself will not separated from an interface who created to connect between humans and computers in this case a smart home device was made. This study aims to design a GUI interface for LoRa-based smart home and implement a smart home system using applications that can control LoRa-based household electronic devices. The results of this study are devices for applying LoRa-based smart homes and web-based applications as interfaces so that users can use smart home devices. LoRa Dragino is used as a client and server communication tool and the NodeMCU (ESP8266 Module) is used as a liaison between the server and the user through the GUI interface created. This web-based application is compatible with Android 6.0, 7.1.2, 9.0, 10.0, and iOS 9.3.5, and various browsers such as Internet Explorer, Mozilla Firefox, and Google Chrome. The test results of the interface design are made with a 10 times test of each feature that produces 0% error, which means that the features contained in the interface design are made to work according to plan. The average delay when controlling a household electronic device is 3.86 seconds. The furthest communication distance between the LoRa Server and the LoRa Client is 63 meters in blocked space and 183 meters in semi open space.
