You see my computer on the left and my coffee roaster on the right. I lashed out and purchased a Hottop KN-8828B-2K+ which has USB control. I have had this roaster almost since it was first released onto the market, probably late 2015. When I purchased it, there was no actual software available for it but in my research I came across the Open Source Artisan software and thought I would give that a try.
