> +Question:+
> Sending commands to devices in FIWARE Orion is not working
> +Description:+
> I am trying to provide a device on FIWARE and send commands. In my case, a lamp with commands ("on" and "off"). But, it's not working. 
> The steps to create a device and send command are:
> Provide a device;
> Create a service group;
> Create a registration with commands;
> Send a command.
> I'm taking the fiware-tutorials following the steps, but don't work. 
> The code I have used was:
> To create a device:
> curl -iX POST \
>   'http://localhost:4041/iot/devices' \
>   -H 'Content-Type: application/json' \
>   -H 'fiware-service: openiot' \
>   -H 'fiware-servicepath: /' \
>   -d '{
>   "devices": [
>     {
>       "device_id": "lamp1",
>       "entity_name": "urn:ngsi-ld:Lamp:1",
>       "entity_type": "Lamp",

> To create a service group:

> To create a registration for commands:
> curl -iX POST \

>   -H 'Content-Type: application/json' \
>   -H 'fiware-service: openiot' \

>   "dataProvided": {

>   "provider": {
>     "http": {"url": "http://orion:1026/v2"},

> To send a "on" command:
> curl -iX PATCH \
>   'http://localhost:1026/v2/entities/urn:ngsi-ld:Lamp:1/attrs' \

>   -d '{
>   "on": {
>       "type" : "command",
>       "value" : ""
>   }

> Doing a HTTP get request to retrieve the entity:
> curl -G -X GET \
>   'http://localhost:1026/v2/entities/urn:ngsi-ld:Lamp:1' \
>   -d 'type=Lamp' \
>   -d 'options=keyValues' \
>   -H 'fiware-service: openiot' \
>   -H 'fiware-servicepath: /'
> I expect a output like:
> {
>   "id": "urn:ngsi-ld:Lamp:001",
>   "type": "Lamp",
>   "TimeInstant": "2019-08-28T13:33:51.00Z",
