IoT Device Management Demo
Eclipse Mosquitto + InfluxDB
Developed IoT platform demo showcasing modern device management patterns. System implements MQTT 5.0 message broker (Eclipse Mosquitto) for device communication, device shadow synchronization for offline-first operation, InfluxDB time-series storage for sensor telemetry, OTA firmware update mechanism with delta compression. Demonstrates X.509 certificate-based device authentication, bi-directional MQTT pub/sub for commands/telemetry, edge computing patterns. React dashboard for real-time device monitoring with WebSocket updates. Supports smart home and industrial IoT use cases.
The Challenge
IoT requires device provisioning, firmware updates, telemetry processing, remote control. MQTT protocol complex with QoS levels. Device shadow pattern needed for offline-first. Time-series storage for sensor data. Security critical: X.509 certificates, mTLS. OTA firmware updates need delta compression. Real-time monitoring dashboard requires WebSocket.
The Solution
Built IoT demo with Eclipse Mosquitto MQTT broker, device shadow sync pattern, InfluxDB time-series storage. X.509 certificate-based device authentication. OTA update mechanism with delta compression. React dashboard with real-time WebSocket updates. Python device simulator. Demonstrates production IoT patterns for smart home and industrial use cases.
