Fiware：通過IDAS註冊/發送時Orion CB沒有觀察屬性UltraLight

Question

這個問題與Missing attributes on Orion CB Entity when registering device through IDAS非常相似，但是在那裏沒有發現確切的答案。

我一直在試圖通過FiWare IDAS獲得UL2.0在Fiware-Lab的ENV獵戶座CB工作：使用最新的GitHub

我有一個帶有令牌生成的FI-WARE實驗室帳戶。適於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=/

host=130.206.80.40

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

[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 

我用SENSOR_TEMP模板，加入 '協議' 字段（PDI-IOTA-超輕其作爲第一個問題，我偶然發現）：

{ 
"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" 
     } 
     ] 
     } 
    ] 
    } 

現在我可以註冊設備好。像

python RegisterDevice.py SENSOR_TEMP NexusPro Temp-Otterlo 

，並看到它在設備列表：

python ListDevices.py 

我可以把諸如此類的觀察

python SendObservation.py Temp-Otterlo 'otemp|17' 

但在ContextBroker我看到實體，但從來沒有測量，例如

python GetEntity.py Temp-Otterlo

} 

我得到一個TimeInstant屬性奇怪。我嘗試使用.ini的設置玩弄fiware-service = fiwareiot，但無濟於事。我沒有想法。目錄中的文檔。對於IDAS4 正在討論意見將被髮送到端口8002並設置「OpenIoT」服務，但也失敗了。

任何幫助表示讚賞。

Answer 1

您應該運行「python SendObservation.py NexusPro'otemp | 17'」而不是「python SendObservation.py Temp-Otterlo'otemp | 17'」。

原因是你在南行提供了一個觀測值，然後應該使用DEV_ID。

實體不包含屬性，直到收到觀察結果，然後這是正常的，你無法看到它。一旦你嘗試上面的一個應該都可以工作。

乾杯，
