IoT Smart Distribution Box (SDB) for Homestay Energy Management System by Using Arduino and ESP32

This paper presents the design and implementation of a Smart Distribution Box (SDB) system aimed at addressing energy waste behaviour by tenants of homestays during vacation periods. The system empowers homestay owners to efficiently control and monitor energy usage at their properties through a user-friendly Blynk application combined with a GSM SIM900A control system. Consumers can also proactively limit their energy consumption based on their recharged balance within the system. The SDB includes a user-friendly Distribution Box (DB) that facilitates monitoring and controlling energy usage during stays. Additionally, a mock payment system has been developed for tenants, using messages sent to a GSM SIM 900A connected to an Arduino Uno and an ESP32 to link the Blynk apps for the owner to the system. The results demonstrate the versatility of the system, which operates in various modes such as standby mode, recharge mode, usage mode, low balance mode, and owner mode for the homestay. By effectively managing energy consumption between tenants and owners, the system streamlines the payment process for energy usage and allows for upgrading the DB system as technology evolves.
