Question:
Fiware IoT Agent UL: Send command_value via mqtt to device

Description:
I am using the IoT-agent for ultra light and I'd light to send a command back to my IoT-Device. If I follow the example for a smart door here I can send something like:

curl -iX POST \
'http://localhost:1026/v2/entities/urn:ngsi-ld:pysense:002/attrs' \
-H 'Content-Type: application/json' \
-H 'fiware-service: openiot' \
-H 'fiware-servicepath: /' \
-d '{
"color":

}'

Fiware publishes the payload "urn:ngsi-ld:pysense:002@color|" to my mqtt-broker. But I would expect the value of "100" to be passed as well?

I also found this documentation on Git regarding mqtt-commands. But that one does not specify where to send that and how? I suppose it uses the the same URL as this request: http://localhost:4041/v1/updateContext
?? Is that the up-to-date way to issue commands?

I am using Orion-ld and the iotagent-ul:1.8.0.

Can somebody help me getting the value of "color" into the mqtt-message as well?

Thank you!
