Requirements

The ability to track Exhaust, Inlet, and Drum temperatures on your roast machine depends on factors such as the model, year, and the presence of the Diedrich sensor package.

Establishing a connection to the machine

Troubleshooting


If you have followed the setup instructions for a measurement but still cannot see its temperature values on RI, your Diedrich roast machine may not have a temperature sensor to track the measurement in question.

Please make sure to verify the following:
  • Does your Diedrich roast machine have Diedrich's sensor package (indicated by a USB port)?
    • Is the Diedrich connected to the computer via USB? 
  • Is the Phidgets driver installed?
  • Mac only: has the Phidgets driver been enabled in the Mac's Security & Privacy settings?
