IoT Device-Controlled Application

Overview

A real-time IoT platform for a smart building solutions company. The platform monitors thousands of sensors across commercial buildings, controlling HVAC, lighting, and security systems based on occupancy and time of day.

?

The Challenge

Building managers had no visibility into energy usage or equipment performance. Issues were reported by tenants (too hot, lights out) rather than detected proactively. The client needed a system that could collect sensor data, analyze patterns, and automate responses.

The Solution

We developed a Next.js dashboard that connects to MQTT brokers receiving sensor data. Real-time updates show building status, and automated rules adjust settings based on occupancy. Historical data helps identify optimization opportunities and predict maintenance needs.

Key Features

Real-time sensor data visualization
Automated rule engine for device control
Predictive maintenance alerts
Energy consumption analytics
Tenant portal for comfort preferences
Mobile app for facility managers
Historical data export for reporting
Alert system for critical events

Key Results

01Energy costs reduced by 28% through smart automation
02Preventive maintenance alerts reduced emergency repairs by 65%
03Tenant complaints dropped by 80%
04System handles 1M+ messages daily from 5,000+ devices
05Payback period: 14 months
