🔐 IoT Devices ↔ MQTT TLS (8883) ↔ Django ↔ WebSocket Dashboard
🔐 How Your Devices Stay Secure
- MQTT over TLS 1.3 (Port 8883) — Encrypted communication
- MAC-based session binding — Cryptographically bound to MAC address
- Encrypted WiFi credentials — No plain text passwords
- Single-use registration tokens — 24-hour expiry
- Rate limited tokens — 60 requests/minute max
- Auto session renewal — Every 120 hours
- Auto IP banning + Self-unban — Visit /self-unban/
Control from Anywhere
Control relays, monitor temperature, soil moisture, rain alerts — from your phone. No local network needed.
Real-Time Dashboard
WebSocket updates under 100ms. No page refresh. Instant relay toggling.
