What URL to use for http request node?

General
1

Hey All.
First time working with JSON and I'm setting up a http request node but I don't know what URL to use. I'm working on a local network.

The JSON I'm interested in is coming from a form on the dashboard and I'm trying to show the data on the same dashboard. How do I know what URL to use for the IP address?

this is the address of my dashboard.

http://192.168.1.***:1880/ui/#!/0?socketid=5Y9uUwVVuL7ozybRAAAB

the variable I want is called deskBrightness I think it should look something like this but it doesn't work...

http://192.168.1.***:1880/ui/#!/0?socketid=5Y9uUwVVuL7ozybRAAAB{{{deskBrightness}}}

Please check out my flow if you have a minute.
Thanks
Rich

Why do you need to use the http request node for the dashboard ?
Can you explain what you are trying to achieve ?

I'm also sending the data to an Arduino but it doesn't understand JSON. I'm trying to view the Int inside the JSON file.

How can I do this?
Thanks

I've done some more reading but I'm still stuck. Maybe something like this?

FYI: there is an Arduino Json library
