fiware-orion - サブスクリプション後に Orion Context-broker から通知を受信しない

Question

「ユーザーとプログラマー ガイド」で例を試していますが、サブスクライブした後、通知を受け取ることができません。更新とクエリはうまく機能しています。「受容体」スクリプトはこのように開始されます

./accumulator-server.py 1028 /accumulate on

そしてそれは稼働しているようです

verbose mode is on
 * Running on http://0.0.0.0:1028/ 

その後、サブスクリプションも問題ないようです

(curl localhost:1026/NGSI10/subscribeContext -s -S --header 'Content-Type: application/json' --      header 'Accept: application/json' -d @- | python -mjson.tool) <<EOF
{
    "entities": [
        {
        "type": "Room",
        "isPattern": "false",
        "id": "Room1"
    }
],
"attributes": [
    "temperature"
],
"reference": "http://localhost:1028/accumulate",
"duration": "P1M",
"notifyConditions": [
        {
            "type": "ONTIMEINTERVAL",
            "condValues": [
                "PT10S"
            ]
        }
    ]
    }
   EOF

応答：

{
    "subscribeResponse": {
    "duration": "P1M", 
    "subscriptionId": "535e558d28604367380deb5c"
    }
}

次に、Room1 の更新

curl  -v localhost:1026/NGSI10/updateContext --header 'Content-Type: application/json' --header 'Accept: application/json' -d @-  <<EOF
> {
>     "contextElements": [
>         {

>             "isPattern": "false",
>             "id": "Room1",
>             "attributes": [
>             {
>                 "name": "temperature",
>                 "type": "centigrade",
>                 "value": "x"
>             },
>             {
>                 "name": "pressure",
>                 "type": "mmHg",
>                 "value": "x"
>             }
>             ]
>         }
>     ],
>     "updateAction": "UPDATE"
> }
> EOF

        "reasonPhrase" : "OK"
      }
    }
  ]
}
* Connection #0 to host localhost left intact
* Closing connection #0

しかし、accumulator-serverの出力には何も表示されません

私が間違っている可能性があることについて何か考えはありますか？
