> Dear Daniel,
> my name is Stefano Valtolina and I work at the Department of Computer 
> Science of the University of Milano.
> I'm writing you because  we are trying to implement an IOTarchitecture 
> by using Orion and the IoTAgent but we have some problems.
> We followed the instruction reported at this link:
> https://github.com/telefonicaid/iotagent-json/blob/master/docs/stepbystep.md
> We installed:
> - mosquitto MQTT v3.1 broker.
> - Orion - FIWARE NGSI version 2 API.
> - Node.js v.6.11.0
> - MongoDB v2.4.14
> if i call the command
> curl http://localhost:4041/iot/about
> I have
> {"libVersion":"2.4.0-next","port":4041,"baseRoot":"/","version":"1.5.0-next"}
> When we try to provision the device (e.g the sensor01 as reported in the 
> example) we don't have any messages of error but the final registration 
> in Orion does not seem to be successful.
> This because after the execution of  following two commands:
> mosquitto_pub -t /1234/sensor01/attrs -m '{"l":4,"t": "31.5"}'
> curl -X POST -H "Content-Type: application/json" -H "Accept: 
> application/json" -H "Fiware-Service: myHome" -H "Fiware-ServicePath: 
> /environment" -d '{
>      "entities": [
>          {
>              "isPattern": "false",
>              "id": "LivingRoomSensor",
>              "type": "multiSensor"
>          }
>      ]
> }' 'http://localhost:1026/NGSI10/queryContext'
> the resulting response is empty
> {
>    "contextResponses" : [
>      {
>        "contextElement" : {
>          "type" : "multiSensor",
>          "isPattern" : "false",
>          "id" : "LivingRoomSensor",
>          "attributes" : [
>            {
>              "name" : "Luminosity",
>              "type" : "lumens",
>              "value" : ""
>            },
>            {
>              "name" : "Temperature",
>              "type" : "celsius",
>              "value" : ""
>            }
>          ]
>        },
>        "statusCode" : {
>          "code" : "200",
>          "reasonPhrase" : "OK"
>        }
>      }
>    ]
> }
> and in Orion the new device does not appear.
> Please could you give us some indication of where we're going wrong.?
> Sorry for bothering you  but we are not very familiar about this type of 
> iot architecture and any suggestions can be very useful.
> Best regards
> Stefano
