DESCO-Control - IoT Electricity Management System
An IoT-powered electricity management system built with Next.js, Firebase Realtime Database, and NodeMCU for real-time power control.
DESCO-Control is an IoT-based real-time electricity management platform developed for Dhaka Electric Supply Company Limited (DESCO). It allows administrators to remotely control electricity connections (ON/OFF), monitor status, and track activities with full transparency. The system integrates both software (Next.js, Firebase) and hardware (NodeMCU, Relay Module) to create a seamless and modern electricity management experience.
Background & Inspiration
This project was initially developed during my time at Dhaka Polytechnic Institute. While studying there, I noticed how DESCO administrators were struggling with manual workflows for electricity control. That inspired me to create a solution that bridges the gap between academic learning and real-world problems. DESCO-Control was born out of the need to solve a local, practical infrastructure challenge while applying cutting-edge IoT and web technologies.
Project Overview
Traditionally, DESCO administrators relied on manual workflows to control electricity connections, which was slow, complex, and error-prone. DESCO-Control solves this by using Firebase Realtime Database for instant synchronization and IoT hardware (NodeMCU + Relay Module) for physical control of electrical lines. This enables secure, fast, and automated electricity management.
Key Features
- User Lookup: Instantly search customers by Name or Meter ID.
- Remote Connection Control: Toggle electricity supply ON/OFF via IoT-enabled relay modules.
- Real-time Monitoring: Instantly reflect user connection status across the system with Firebase Realtime DB.
- Activity Logging: Maintain detailed logs of every admin action (ON/OFF switch, user details, timestamps).
- Secure Access: Only authorized administrators can manage connections through role-based authentication.
Objectives
- Faster: Real-time IoT control reduces delays in managing connections.
- Safer: Enforced authorization ensures only trusted admins can operate.
- Transparent: Centralized logging provides accountability and traceability.
- Efficient: Automation reduces manual errors and operational costs.
Technologies & Tools
- Next.js to Scalable frontend framework.
- Firebase Realtime Database to Instant synchronization & live monitoring.
- NodeMCU (ESP8266) to IoT microcontroller for hardware integration.
- Relay Module to Physical ON/OFF electricity control.
- Tailwind CSS / Shadcn UI to Clean and responsive UI design.

Summary
DESCO-Control modernizes DESCO's electricity management by combining IoT hardware with real-time software. It brings together instant synchronization, security, and transparency into one powerful system. Developed originally at Dhaka Polytechnic Institute, this project is a proof of how academic learning can be applied to create real-world infrastructure solutions.
