SmartFlow (“Application de supervision de données temporelles” — temporal data monitoring application) is a small Python stack for collecting and visualizing sensor data over time. It is made of two parts: a harvester (harvester.py) that regularly retrieves sensor data from an origin server and stores it as JSON, and a web application (app.py) that serves the collected data for analysis and monitoring. The deployment stack targets a Linux server with gunicorn, Nginx, and supervisor.
