[英]Missing attributes on Orion CB Entity when registering device through IDAS
[英]Fiware: No observation attributes in Orion CB when registered/sent via IDAS UltraLight
這個問題非常類似於Orion CB Entity在通過IDAS注冊設備時的缺失屬性,但在那里沒有找到明確的答案。
我一直在嘗試使用IDWare通過IDAS將UL2.0送到在Fiware-Lab環境中工作的Orion CB:
我有一個FI-WARE Lab帳戶,生成了令牌。 修改了config.ini文件:
[user]
# Please, configure here your username at FIWARE Cloud and a valid Oauth2.0 TOKEN for your user (you can use get_token.py to obtain a valid TOKEN).
username=MY_USERNAME
token=MY_TOKEN
[contextbroker]
host=130.206.80.40
port=1026
OAuth=no
# Here you need to specify the ContextBroker database you are querying.
# Leave it blank if you want the general database or the IDAS service if you are looking for IoT devices connected by you.
# fiware_service=
fiware_service=bus_auto
fiware-service-path=/
[idas]
host=130.206.80.40
adminport=5371
ul20port=5371
OAuth=no
# Here you need to configure the IDAS service your devices will be sending data to.
# By default the OpenIoT service is provided.
# fiware-service=fiwareiot
fiware-service=bus_auto
fiware-service-path=/
#apikey=4jggokgpepnvsb2uv4s40d59ov
apikey=4jggokgpepnvsb2uv4s40d59ov
[local]
#Choose here your System type. Examples: RaspberryPI, MACOSX, Linux, ...
host_type=MACOSX
# Here please add a unique identifier for you. Suggestion: the 3 lower hexa bytes of your Ethernet MAC. E.g. 79:ed:af
# Also you may use your e-mail address.
host_id=a0:11:00
我使用了SENSOR_TEMP模板,添加了'protocol'字段(PDI-IoTA-UltraLight,這是我偶然發現的第一個問題):
{
"devices": [
{ "device_id": "DEV_ID",
"entity_name": "ENTITY_ID",
"entity_type": "thing",
"protocol": "PDI-IoTA-UltraLight",
"timezone": "Europe/Amsterdam",
"attributes": [
{ "object_id": "otemp",
"name": "temperature",
"type": "int"
} ],
"static_attributes": [
{ "name": "att_name",
"type": "string",
"value": "value"
}
]
}
]
}
現在我可以注冊設備了。 喜歡
python RegisterDevice.py SENSOR_TEMP NexusPro Temp-Otterlo
並在設備列表中看到它:
python ListDevices.py
我可以像發送Observations一樣發送
python SendObservation.py Temp-Otterlo 'otemp|17'
但是在ContextBroker中我看到實體但從未進行過測量,例如
python GetEntity.py Temp-Otterlo
給
* Asking to http://130.206.80.40:1026/ngsi10/queryContext

},
{

}
]
}
]
},
"statusCode" : {
"code" : "200",
"reasonPhrase" : "OK"
}
}
]
}
我奇怪地得到了一個TimeInstant屬性。 我嘗試使用.ini的設置,如fiware-service = fiwareiot,但無濟於事。 我沒有想法。 目錄中的文檔。 IDAS4正在討論要發送到端口8002並設置“OpenIoT”服務的觀察,但也失敗了。
任何幫助贊賞。
你應該運行“python SendObservation.py NexusPro'otemp | 17'”而不是“python SendObservation.py Temp-Otterlo'otemp | 17'”。
原因是您在南行提供觀察,然后應使用DEV_ID。
在收到觀察結果之前,實體不包含屬性,因此您無法看到它。 一旦你嘗試了上面的那個,它應該都可以工作。
干杯,
