What are the application for PIO Remote ? Why do we need to remote upload a programm (anywhere in the world) ?
I, personally, find it very useful. I have a Udoo-x86 board, which is basically a PC with a built-in arduino. It is located somewhere else, connected to the real devices it controls, but I can still develop the code on my workstation and upload it with a press of a button to the remote board like it is plugged into my workstation. I can, probably, copy it manually there instead, and use Arduino CLI or something to flash the board remotely through SSH, but why bother when there is a better way?
