IoT Nexus
Unified dashboard and real-time controller for domestic devices

Key Achievements
Created a mobile app dashboard displaying live telemetry (temperature, light levels, energy metrics) with WebSockets
Configured an MQTT message broker running on Raspberry Pi to dispatch device status adjustments under 50ms latency
Programmed automated power scheduler rules that adapt to user behaviors, decreasing average energy consumption by 20%
The Challenge
Smart home appliances use fragmented protocols, leading to a clunky user experience. The client wanted a centralized local-first system that monitors metrics and triggers adjustments instantly.
Strategy & Implementation
We chose MQTT for its lightweight footprint on local microcontrollers. We combined it with a Node.js gateway that bridges MQTT topics to WebSockets, allowing the React Native dashboard to display smooth, real-time gauges and switches.
Impact & Results
Achieved sub-50ms command latency for lights and thermostats, along with a 20% average electricity savings for users.
