Unable to send commands to sensor through Orion Context Broker
Hello, I am hoping you can assist me with a problem I am experiencing.
I have set up the LoRaWAN IoT Agent with TTN, correctly providing the ApiKey and establishing the flow between the sensor and Orion. I am able to successfully retrieve and store data from the sensor.
However, I am encountering an issue when attempting to send a command to the sensor through a PATCH request in the Orion Context Broker.
What I send to Orion Context Broker is the following:
curl --location --request PATCH 'http://localhost:4041/v2/entities/urn:LoraDeviceGroup:eui-70b3d57ed8001231/attrs' \
--header 'accept: application/json' \
--header 'Fiware-Service: openiot' \
--header 'Fiware-ServicePath: /' \
--header 'Content-Type: application/json' \
-d '{
"on": {
"type": "command",
"value": ""
}
}'
What I receive is the following (404 not found):
{
"error": "NotFound",
"description": "The requested entity has not been found. Check type and id"
}
That sounds quite weird, since all the entities in the IoTA and Orion Context Broker were automatically created by the IoTA since I've created a sensor group.
This is the body of my POST request that I've sent to the IoTA while creating the service group:
{
"services": [
{
"entity_type": "LoraDeviceGroup",
"apikey": "",
"resource": "XXXXXXXXXX",
"commands":[
{
"object_id": "on",
"name": "on",
"type": "command"
},
{
"object_id": "off",
"name": "off",
"type": "command"
}
],
"attributes": [
{
"object_id": "rh0",
"name": "relative_humidity_0",
"type": "Number"
},
{
"object_id": "t0",
"name": "temperature_0",
"type": "Number"
},
{
"object_id": "bp1",
"name": "barometric_pressure_1",
"type": "hpa"
},
{
"object_id": "t1",
"name": "temperature_1",
"type": "Number"
},
{
"object_id": "t2",
"name": "temperature_2",
"type": "Number"
}
],
"internal_attributes": {
"lorawan": {
"application_server": {
"host": "eu1.cloud.thethings.industries",
"username": "XXXXXXXXXX",
"password": "XXXXXXXXXX",
"provider": "TTN"
},
"app_eui": "XXXXXXXXXX",
"application_id": "XXXXXXXXXX",
"application_key": "XXXXXXXXXX",
"data_model": "application_server"
}
}
}
]
}
If I retrieve the entity from the context broker this is what I get:
{
"id": "urn:LoraDeviceGroup:eui-70b3d57ed8001231",
"type": "LoraDeviceGroup",
"TimeInstant": {

}
},

}
},

"value": 23.8,
"metadata": {
"TimeInstant": {
"type": "DateTime",

}
}
},
"temperature_2": {
"type": "Number",
"value": 24,
"metadata": {
"TimeInstant": {
"type": "DateTime",
"value": "2023-04-28T10:01:52.894Z"
}
}
},
"on": {
"type": "command",
"value": "",
"metadata": {}
},
"off": {
"type": "command",
"value": "",

}
}
Also, all the registrations are correctly set up:
{

"dataProvided": {
"entities": [
{
"id": "urn:LoraDeviceGroup:eui-70b3d57ed8001231",
"type": "LoraDeviceGroup"
}
],
"attrs": [
"on",
"off"
]
},
"provider": {
"http": {
"url": "http://localhost:4041"
},
"supportedForwardingMode": "all",
"legacyForwarding": false
},
"status": "active"
}
These are the logs regarding my PATCH request:
