I'm trying to implement an option in node-red and I don't know how to approach it.
What I want to do is a node with a button, that when I press it, I will compare the name of the n file locally with another in an ftp, and if it is different, that of the option to download it.
It would be very similar to the option of looking for new firmware in a router for example.
I'm stuck at first because I wouldn't know how to tell it to compare the file name in the function ...
Thanks and regards!
