This manual explains how to connect a HB roast machine to the Cropster Roasting Intelligence

If you haven't been invited to participate in the beta program for this integration, but you are interested in participating and testing the feature, please sign up here.

Beta means that the features are being tested with a select group of users to help us identify minor flaws under everyday conditions that we cannot reproduce internally. Therefore, it will be necessary that you share feedback with us and let us know whenever you come across some unexpected behavior.

Customize your RI user preferences


If the RI indicates No source connected and/or you cannot see any measurements, please check the following: 

  • Is the roast machine connected to the computer? 
  • Have you downloaded the required driver for the USB serial converter, according to the manufacturing year of the machine?
  • Is the correct serial port within the RI selected?
