-
-Create two NGSI-LD agents :
-
-- the first one collects data from parking spots in-ground sensors and cameras then updates the parking spots entities in the broker
-- the second one subscribes to parking spots events then updates values in the parking entity, such as the occupancy ratio
-
-Below the code to create the subscription needed by the second agent.
-
-```python
-from ngsildclient import SubscriptionBuilder, Client
-
-subscr = SubscriptionBuilder("http://dummy.parkingmanagement.com:8000/parking_spots")
-    .description("Notify me of parking spot movements")
-    .select_type("ParkingSpot").watch(["status"])
-    .build()
-
-with Client(port=8026, port_temporal=8027) as client:
-   subscr_id = client.subscriptions.create(subscr)
-```
-
-The following subscription payload has been generated.
-
-```json
-{
-    "type": "Subscription",
-    "description": "Notify me of parking spot movements",
-    "entities": [
-        {
-            "type': 'ParkingSpot"
-        }
