we are going to do here is look at how
to sit up and convey the Inka to the
advanced listener agent this agent
allows the user to receive data from a
device or other source by listening to a
specific MQTT topic as little device
publishes the data to that amputated
channel or topic I'm going to add this
agent to my canvas now so I'm going to
go to the toolbox and search for it
you'll find it on the listeners to add
it to the canvas click on it and drag it
to the canvas and drop it you will see
that this agent has a default name given
to it you can rename this item by
clicking on the white space and start
typing click some mouse on the canvas
and click Save you configure this item
click on it and click on configure first
make sure you using the correct
collection if you'd like to change this
just select another collection from the
drop-down next you need to specify your
broker address I'm going to use a public
channel for this example then specify
the name of your channel or topic at the
port number you'd like to use and
specify unique client ID
next you need to select your quality of
service three options is available at
most once at least once and exactly once
I'm going to leave it with the default
option then you have to the choice
whether to create a clean session or not
I'm just going to leave the default
option as is if you need to use a secure
Channel when publishing or listening to
messages you can select this checkbox
you they need to specify your protocol
from choosing one of the options in the
drop-down and upload the appropriate
certificates and specify your client
certificate password this example I'm
not going to use a secure channel if you
have credentials configured you can add
your username and password in here if
not just leave these options empty then
you need to specify the format of your
file light which can be either JSON or
hex my pilot will be in JSON so I'm
going to leave it as is if your panel
has a nested structure you need to
specify the path for your Jason so then
you need to select this box use this
sample here to specify your path
you'd like to include those messages in
your pilot you can select the box lastly
you need to specify the payload I'm
going to add a new row by clicking on
the plus and add my items
then specify a datatype click somewhere
else on the canvas take apply click Save
now I'm going to use MQTT effects to
publish the readings to mqtt to run your
stream click on publish to view the
library click on live view select your
agent and click Save I have one
temperature reading here which are going
to publish as you can see in the
background it came through in my live
you
