About Grand Diara Hotel
Located in the scenic highlands of Puncak, West Java, Grand Diara Hotel is a well-known accommodation for both business and leisure travelers. With increasing demand and a growing number of rooms, efficient energy management became a top priority for the hotel’s management.
The Challenge
Grand Diara Hotel needed a reliable system to track electricity usage in every room and generate accurate reports to help optimize their operational efficiency. Manual monitoring was not only time-consuming but also prone to human error, making it difficult to take quick, data-driven actions.
Our Solution
We developed a customized IoT-based electricity usage monitoring system, composed of two main components:
-
IoT Platform: Built using NodeMCU microcontrollers paired with current sensors, installed in every hotel room. These sensors capture real-time electricity data.
-
Server System: A centralized backend developed in Java, designed to collect, process, and display electricity usage data in real time.
Key Features
-
Live Usage Monitoring: The system provides a dashboard showing real-time electricity consumption per room.
-
Custom Reports: Management can generate reports for specific dates, rooms, or usage patterns.
-
Operational Insights: By comparing usage trends, stakeholders can detect anomalies and make informed decisions.
-
Scalable Architecture: The system is designed to scale with the hotel’s expansion or additional facility integration.
Business Impact
With the new monitoring system in place, Grand Diara Hotel has significantly improved its ability to:
-
Identify energy inefficiencies.
-
Reduce unnecessary electricity waste.
-
Improve cost forecasting and budgeting.
-
Understand guest usage patterns for future energy-saving strategies.
Smart Technology for Sustainable Operations
This project highlights how technology can be leveraged to drive digital transformation in hospitality. By combining IoT with enterprise-grade software, Grand Diara Hotel now leads by example in adopting eco-conscious, data-driven management practices.
