i have a question about best practice to achieve what i want to do. I would like to have a sketch setup, and then to be able to deploy to different devices of the same type, but each device/node will have a few different parameters, like ip address and mqtt topic etc,
What would be the quickest way to be able to upload new changes to all of my nodes without having to track my changes and update each seperate sketch for each node?
I was thinking about using some IFDEF statements if i can figure out how to? would that be the best way to go or is there something better?
Thx in advance
