Fermín Galán commented on HELP-8385:
------------------------------------

Not directly related with Orion, but with IOTA-LWM2M. Thus, assigning back to Backlog Manager in the hope he can assign to the right people.

> +Question:+
> Querying lwm2m active attribute in Orion
> +Description:+
> I have the following configuration for an active lightweightm2m-iotagent attribute (a temperature sensor value). Fiware's IoT agent turns IPSO objects into lazy attributes but I add a mapping to make it an active attribute as in the documentation:
>   types: {
>     'Type': {
>         service: 'service',
>         subservice: '/service',
>         commands: [],
>         lazy: [],
>         active: [
>           {
>             "name": "t",
>             "type": "number"
>           }
>         ],
>         lwm2mResourceMapping: {
>           "t": {
>             "objectType": 3303,
>             "objectInstance": 0,
>             "objectResource": 5700
>           }
>         }
>     },
> According to the documentation for the iotagent-node-lib:
>   NGSI queries to the context broker will be resolved in the Broker database.
> However, when I query my active attribute in Orion, Orion also queries the lightweightm2m-iotagent, requesting a bogus /3303/0/0 path which doesn't even exist in the IPSO definition.
> curl -H "Fiware-service: service" -H "Fiware-servicepath: /service" http://172.17.0.1:1026/v2/entities/entity1:Type/attrs/t/value
> How can I set up the configuration to get the behavior stated in the documentation, resolving a query for an active attribute in the broker database and avoiding these bogus queries?
