Topic sensor network
From AMTech WikiDocs
When an observation type instance is posted to the endpoint /amtech/things/events:
- the observation gets validated versus the semantic of the '@type'
- #{placeholders} get enriched
- location and proximity enrichment happens
If an error occurs an observation type observationoutputmsg get send to the sensor network topic /sensor_network/observation_errors/observationTypeName in the following example is an observation type observationresourcecrud sent with a wrong topic value "message": "Failed registering topic for observation"
