- 1Hardware: Wire relays and sensors to an ESP32; publish/subscribe sensor and control topics over MQTT.
- 2Broker + backend: Run an MQTT broker; bridge messages to a Node.js backend storing telemetry.
- 3App control: Build a dashboard to toggle devices, view live sensor data, and set schedules.
- 4Automation: Add rules (e.g. turn on fan above a temperature) and push alerts on thresholds.
Key features to implement
- ✓Remote appliance control
- ✓Live sensor telemetry
- ✓Time-based schedules
- ✓Threshold automation rules
- ✓Push alerts
💡 Unique twist to stand out
Add an offline fallback so the ESP32 keeps running local rules even when the internet/broker is down.
