How does the "Temperature based auto-start and end" detection work
Table of Contents
Overview
This article explains how the "Temperature-based auto-start and end detection" works, and how to enable it.
Instructions
Temperature-based Auto-start/End (formerly "Automatic start and end detection") is a Roasting Intelligence feature that improves roast accuracy.
It works by detecting the sharp temperature drops that occur when beans are loaded (charged) into the drum or unloaded (discharged) at the end. By identifying these thermal shifts, Roasting Intelligence ensures your roast data is captured with precision.
Enabling the "Temperature-based auto-start and end detection" feature
- Log in to Roasting Intelligence.
- Navigate to
Preferences > Roasting tab > Smart features > Smart detection section. - Check the "Machine event-based auto-start and end of roast detection" box to enable the feature.
-
Click Save to finalize the changes.
-
Restart Roasting Intelligence.
Setting values for the temperature drop that will start your roast timer
⚠️ Ensure Temperature Stability
When using temperature-based detection, make sure the bean temperature is stable (not decreasing) the moment you charge the drum. If the temperature is already falling, the system may fail to detect the start of your roast.
- Detect start when temperature drops by: When you set the temperature to 7ºC/13ºF, the roast timer will activate once the temperature consistently remains at 7ºC/13ºF for at least 30 seconds. This marks the beginning of the roasting process.
- Detect end when temperature drops by: When a second temperature drop is detected, the Roasting Intelligence identifies this as the end of the roast. For example, if you set the threshold to 3ºC/5ºF, the roast timer will register the end of the roasting process once the temperature consistently decreases by 3ºC/5ºF over 5 seconds.
Tip:
If your temperature readings are "noisy" or "jumping around" due to electrical interference, Roasting Intelligence might trigger a start or stop too early.
This happens because the software detects a sudden jump that mimics the temperature drop it's looking for. If that "jump" hits the required threshold within the detection window (e.g., a 30-second start interval or a 5-second end interval), the system assumes the roast has begun or ended.
