Bisher werden nur daten des Typs "online-level" verarbeitet, aber der Rest sollte einigermassen trivial sein.
|

Ich habe keine Ahnung, wie und in welchem Format ihr das an euren zentralen Thinger Server senden wollt, aber kÃnnt ihr vieleicht auch selber erledigen.

### server-web.py

Hier wird der web server direkt im Programm gestartet. Der Server lauscht auf Port 80. Im docker container gestartet kann man den server auf port 8050 anfragen
|
||||
|
||||
```
|
||||
# Liste mit ids
|
||||
curl http://127.0.0.1:8050/ids
|

# Wert der Id

curl http://127.0.0.1:8050/nmt/6
