IoT platform

Technical details

The backend is built on FastAPI framework, providing high-performance asynchronous API endpoints. We leverage Pydantic for payload validation and automatic OpenAPI/Swagger documentation. Key API routes include device management, real-time data streaming, and batch operations. For the persistence layer, we’ve implemented a hybrid database layer:

• PostgreSQL (with asyncpg driver):

  • Device metadata and configurations
  • User management and authentication
  • Device relationship graphs

• MongoDB (time-series collections):

  • High-frequency telemetry
  • Performance metrics

• FastApi Backend:

Supported protocols

Modbus

• Implemented TCP support
• Asynchronous register reading using pymodbus

MQTT

• Broker: Eclipse Mosquitto
• Hierarchy of topics: /device/{device_id}/{metric_type}

Frontend

The frontend architecture is built around the TanStack framework ecosystem, providing a robust foundation for our application frontend:

• TanStack Router, TanStack Query, TanStack Table and TanStack Form.

Deployment

The entire application runs in Docker containers:

• Separate containers for React Aplication, FastAPI Backend, Postgres, MongoDB and MQTT broker.
