> +Question:+
> FIWARE commands from CB to Ultralight 2.0 device
> +Description:+
> I need to send commands from a FIWARE CB to an UltraLight 2.0 device through an IoT agent via HTTP (polling mode). Although this tutorial only explains how to provision commands for a specific device:
> https://fiware-iotagent-ul.readthedocs.io/en/latest/usermanual/index.html
> I'm trying to provision a couple of commands (no2_offset and no2_factor) for the whole service group as follows:
> HTTP POST http://localhost:4041/iot/services
> {
>   "services": [
>   {
>     "apikey": "si95g7noxpmah9cbx9ggoe36v7",
>     "protocol": ["IoTA-UL"], "cbroker": "http://orion:1026",
>     "entity_type": "myType",
>     "resource": "/iot/d",
>     "attributes": [
>     {
>       "object_id": "t",
>       "name": "temperature",
>       "type": "Number"
>     },
>     {
>       "object_id": "h",
>       "name": "humidity",
>       "type": "Number"
>     },
>     {
>       "object_id": "no2",
>       "name": "NO2",
>       "type": "Number"
>     }],
>     "commands": [
>     {
>       "object_id": "no2off",
>       "name": "no2_offset",
>       "type": "command"
>     },
>     {
>       "object_id": "no2fac",
>       "name": "no2_factor",
>       "type": "command"
>     }]
>   }
> ]}
> The CB accepts the above request without problems. Then I query an entity under the above service group and I get the following response:

> Both commands, along with some *_info and *_status stuff appear integrated among the rest of attributes. Everything looks good to me except for the type=string instead of type=command. In any case, whenever I update the entity with a new command value I never get the command on the device side (body always empty) although getting the entity really shows the update.
> Any idea? Is provisioning commands in the creation of service groups supported?
