Development of a Web Application for Automated Creative Learning Space Services Using IoT through Home Assistant on Local Network

Abstract

The creative learning spaces service at the Office of Academic Resources, Nakhon Phanom University, has experienced continuously increasing user interest. However, challenges emerged including limited staff, dispersed service areas across multiple floors, and an inefficient space reservation system. These issues inspired the development of a new system with the following objectives 1) To develop a web application system for controlling IoT devices through Home Assistant on a local network, 2) To seamlessly integrate the new system with the existing space reservation system to enable automatic collaboration. The project applied the Systems Development Life Cycle (SDLC) methodology combined with Agile principles, using Django Framework to develop a web application to control Sonoff devices with LINE LIFF for identity verification. The results showed that the new system was effectively integrated with the existing space reservation system, provided accurate identity verification, and responded to control commands within 1-2 seconds. Furthermore, the system effectively addressed the issue of overtime usage by managing access based on reservation times and automatically shutting off electrical equipment once the booking period ended. This helped reduce the service providers' operational burden, with an overall user satisfaction rating averaging 4.52.
