The graphical interface provided in the FIWARE tutorials has only been created to provide dummy data into a series of tutorial exercises.
It is used to show how to connect an series of devices using UltraLight over HTTP or MQTT - it is not really designed to be extended or to be
used to display data from a real device - though you could extending that way if you wish.

To connect a series of real devices to the context broker you will need to use an IoT Agent - IoT Agents exist for a series of common protocols
and the one you need to pick will be dependent on the array of device you have - for example a rain-gauge may be very constrained in power
And may be transmitting using LoRaWAN whereas a camera could have a constant power source and may even do image processing on the
Edge.

The full list of available IoT Agents can be found on the FIWARE website: https://www.fiware.org/developers/catalogue/ - you can also
Create your own (based on the Nodejs library) if you are using another protocol.

Having got the data into the context broker, there are several ways you could display the data graphically.

You could use WireCloud or Knowage to create a graphical interface and potentially control your device via button widgets and so-on - more details can be found in the academy courses:

https://edu.fiware.org/course/search.php?search=Wirecloud
https://edu.fiware.org/course/search.php?search=Knowage

To display a graph of historical results you have a choice between Quantum Leap and STH-Comet - Quantum Leap plays nicely with time-based database
And third-party graphical tools like Grafana.

Alternatively you could control the devices by sending NSGI calls programmatically - this is described in the Tutorials, and the code is available within the Tutorials repos

Accessing Context Data

Effectively you would then be modifying the code of the tutorial to do as you require, but it would be a lot of work.

Unless I really needed the extra flexibility, if I were creating a smart application monitoring tool/controller, I wouldn’t be writing it from scratch using nodejs though,
I would definitely look to see if Knowage or Wirecloud offer the functionality you need first before attempting to write my own stuff - there really is no
Need to re-invent the wheel here when the Visualization Generic Enablers already exist for that purpose.

Hi Giovanni,

Assuming you've already managed to get your data into Orion Context Broker
(according to some FIWARE Data Model or not), you can use WireCloud (mashup
application GEri), which serves as dashboarding application easily
connected with Orion data and allows you to define your dashboard by
combining components (widgets and operators) by your own.

A specific guide on this matter is not yet elaborated, but you can find
some information in previous questions like this one:
https://ask.fiware.org/question/1012/create-historic-graph-using-orion-context-broker-data-in-wirecloud-or-other-dashboard/

I'm sorry I cannot give you information on the IoT part, just after
uploading your data to Orion.

Best regards,
