Get started

Create a first very basic NGSI-LD entity.

from datetime import datetime
from ngsildclient import Entity

entity = Entity("AirQualityObserved", "RZ:Obsv4567")
entity.tprop("dateObserved", datetime(2018, 8, 7, 12))
entity.gprop("location", (44, -8))
entity.prop("PM10", 8).prop("NO2", 22, unitcode="GP", userdata={"reliability": 0.95})
entity.rel("refPointOfInterest", "PointOfInterest:RZ:MainSquare")

entity.pprint() # have a look at your just created entity
Send it to the Broker for creation.
It assumes you have a broker instance running locally.
from ngsildclient import Client

with Client() as client:
 client.create(entity)
