SmartCab is a comprehensive smart classroom system designed to make school classrooms safer, more efficient, and more comfortable.
At its core is a hub device (based on Raspberry Pi with touchscreen) that serves as a central interface for teachers and students.

• User Interface
  Intuitive tab-based interface with PIN/NFC access for private sections.

• Environment Monitoring
  Real-time tracking of temperature, humidity, CO₂ levels and more, with alerts when values exceed safe limits.

• Smart Classroom Control

  • Manage lights, smart plugs, blinds, and computers.
  • Remote and mass control via Zigbee, SSH, and Wake-on-WiFi.

• Automation
  Custom scenarios and schedules (e.g., “end of day” routine: turn off lights, shut down computers, close blinds).

• Statistics & Analytics

  • Environment data logs with graphs.
  • Lesson feedback collection from students, stored and visualized for teachers.

• Safety (SOS Button)
  Emergency calls to school security with integrated mic, speakers, and automatic camera snapshots.

• Telegram Bot

  • Control classroom remotely.
  • Export statistics (Excel).
  • Upload lesson schedules.
  • Manage hub PIN settings.

• Online Lessons
  Integrated support for PTZ cameras and VK video conferences, with auto-tracking and dual video streams (screen + camera).

• Core: Raspberry Pi, Zigbee
• Frontend: Vite, TypeScript, React
• Backend: Flask (Python), Go (for camera streaming)
• Databases: SQLite (stats), Redis (devices)
• Messaging: MQTT (Mosquitto, Zigbee2MQTT)
• CI/CD: Docker & Docker Compose, Bash, Vagrant
