Develop IoT Home Automation System

The goal is to deliver a complete, production-ready IoT platform that automates a home’s lighting and HVAC while responding flawlessly to Google Home voice commands.

Core build
• Firmware or edge-side code that speaks to smart switches, dimmers, thermostats and temperature sensors, ideally over MQTT or another low-latency protocol.
• Secure cloud back-end (Node.js, Python, or comparable stack) with REST and WebSocket endpoints so the mobile or web dashboard stays in sync in real time.
• Database layer for device states, schedules and user profiles; relational or NoSQL is fine as long as latency stays low.
• Google Home Action integration, including OAuth flow and fulfilment webhook, so “Hey Google, set living-room lights to 30 %” or “turn on the AC” executes instantly.
• Responsive dashboard where users can create scenes, time-based rules and energy-use reports. Think React, Vue, or Flutter Web—whichever you work fastest in.

Flexibility
The first release must handle lighting and HVAC only; future phases may extend to security cameras, locks or home appliances, so please structure the codebase with modular services and clear device abstractions.

Acceptance criteria
1. A homeowner can add a new light or thermostat from the dashboard and control it within 30 s.
2. Voice commands issued through Google Home reflect on the dashboard in under 2 s round-trip.
3. All traffic encrypted (TLS 1.2+), with JWT-based auth for API calls.
4. Source code, Dockerfiles and infrastructure scripts (Terraform or similar) provided in a private repo, accompanied by concise deployment notes.

Hand-over deliverables
– Source and documentation
– Deployed staging environment URL
– Post-deployment test report covering the criteria above

With those pieces in place, the system will be ready for a quick hand-off and an optional maintenance contract.
