Enabling the machine event-based auto-start and end-of-roast detection

The roast start is triggered once the roast machine's hopper is opened, and the roast end is triggered once the roast emissions door is opened, thus releasing the roasted beans into the cooling tray.

  1. Log in to Roasting Intelligence.
  2. Navigate toPreferences > Roasting > Smart features tab.
  3. Scroll down to the Smart Detection section. 
  4. Enable the machine-based auto-start and end-of-roast detection by clicking on the respective checkbox. 
  5. Click Save.


Troubleshooting

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

  • Is the IP address correct?
  • Is the static IP address set up?
  • Is the right Neuhaus Neotec machine version selected?


Verifying the IP address


If the IP address for your Neuhaus Neotec machine differs from the model's default IP address, refer below to find out how you may identify the IP address, depending on your machine's model.

NEOROAST


The IP address cannot be identified via the machine's user interface or adjusted.

RFB-S


The IP address can be determined and adjusted only by stopping the roast machine's software, using the stop switch on the rear of the panel, and accessing the Control panel’s menu.


RFB Junior
 

The IP address can be determined and adjusted only on the touchscreen panel via the Main menu > IP address.

If the identified IP address differs from the default IP address (e.g., 192.168.111.73), please input the new IP address from the Roasting Intelligence Machine Preferences.

If you have further questions, feedback, or concerns, please submit a support ticket directly from support.cropster.com.
