From a shell, execute ./sensor_data.py. This runs until terminated.
From a shell, execute ./server-ui.py. This starts a Flask server that runs until terminated. The server can be accessed on port 8051 by default.
Edit config.ini. Sensors can be added in the [sensors] section in the format IP address: Display name. Polling interval is configurable (60s by default).
