Artisan. Its the standard for roasting software. You will have to splice a USB cable on to an Arduino, or just buy a usb to dupont cable but its super easy.
If that sounds like a hassle 1. I read that the next version of this roaster will have artisan support built in and 2. The built in profiles are pretty good
I started with the fresh roast, good starter roaster but once you go over 250g, even with an extension tube its rough.
I really liked the bocaboca but for the price the Skywalker kinda blows it out of the water
