You can use telnet to connect to a VideoHub and output the mapping but I wanted something that looked more like the way audio software like x32 or Dante shows a matrix.
So I have written a PowerShell script that outputs the current configuration as an Excel file
Download the script from https://gist.github.com/imorrish/b03fc2e5fbd3fc64de1d010ac79ad0b5
If you are not interested in how the code works …
Here is an exe version that should create the same Excel file of your video hub configuration.
Exe defaults to assuming the local PC is a server for a studio hub. Otherwise you can add an ip address on the command line to connect to a smart hub.
You only need .Net 4.6.1 runtime and Excel 2010 or better, I think (keen for someone to test for me)
Remember to unblock the file after downloading.
I will add lock information as well as Video Monitor outputs for hubs that support that.
