Hottop KN-8828B-2K+

Beginning with Artisan version 0.9.3, support for the Hottop KN-8828B-2K+ home roaster is available. Besides other improvements over previous models, that machine features a USB port that can be used to connect this roaster to a computer running Artisan without requiring any additional hardware or software (see Controlling a Hottop). Artisan allows logging the temperatures from both factory-installed thermocouples of the KN-8828B-2K+ allowing Artisan to read the Environmental Temperature (ET) and Bean Temperature (BT). Artisan also can read the fan speed data (0-10 in increments of 10) and the heater level data (0-100 in increments of 1) from the machine. Finally, by defining some extra buttons and sliders on the Artisan side, it is also possible to fully take control over the machine, setting the heater, fan and even controlling the main motor, cooling tray and drop door. Using Artisan's alarm features it is then possible to run complex roast programs using time and temperature settings in a fully automatic mode if desired.
