See how Roast Pi differs from a simple recording app and how it approaches repeat roasting and environmental analysis.
Start by seeing how Roast Pi interprets repeat-batch flow instead of acting as a simple storage app.
Quickly understand which data is used and what environmental sensors add to the analysis.
Review free-plan access, web analysis, machine connections, and data storage before getting started.
Learn which problems Roast Pi solves and how it differs from conventional roast-logging software.
Roast Pi is a professional roasting platform for analyzing repeatability and flow changes, not just a roast-recording app.
BT, ET, and ROR comparison, profile-variation analysis, and environmental tracking make repeat-batch consistency easier to understand.
Roast Pi goes beyond saving charts and focuses on explaining why a particular roast changed.
It compares temperature, humidity, green-coffee condition, and profile flow together so differences between repeated roasts are easier to see.
Yes.
Basic roast recording and comparison require no specialist knowledge. As your skills grow, you can use environmental analysis, repeat comparison, and flow interpretation in greater depth.
It is designed for work ranging from small sample roasts to repeat-production batches.
It is particularly strong at repeat-batch consistency and profile-comparison analysis.
Understand concepts shown in the analysis screens, including repeat comparison, risk scores, and AI-assisted interpretation.
Roast Pi uses time-series and BT data by default and can record and analyze additional channels such as ET, ROR, and environmental sensors.
Available channels depend on the connected equipment and its configuration.
It overlays BT, ET, and ROR from multiple batches so you can review roast consistency.
You can visually analyze recurring unstable sections and differences associated with environmental changes.
The risk score is a reference indicator combining deviation from a target profile, sudden flow changes, and variation across repeated batches.
It is an analysis tool for spotting profile changes quickly, not a definitive score of final quality.
Some features can analyze differences between a reference profile and the current flow to suggest adjustment directions.
Roast Pi focuses less on simple automation and more on helping users understand the flow.
Roast Pi can analyze flow and deviations from data, but it does not make a definitive sensory-quality judgment.
Its goal is to help users interpret their data and build their own standards.
Learn why environmental changes matter and how to approach sensor and roasting-machine connections.
No.
You can use the core features without a sensor. Adding a temperature and humidity sensor enables more precise analysis of profile differences associated with environmental changes.
Even with the same profile, changes in temperature, humidity, and green-coffee condition can alter the actual roast flow.
Roast Pi records and compares these changes to help improve repeat-roast stability.
Roast Pi is designed to connect with a range of roasting machines, and support continues to expand.
Connection methods and settings can vary by environment, so consult the supported-equipment list and connection guide together.
Review web analysis, internet requirements, the free plan, security, and support before using the service.
Yes.
The free plan includes basic roast recording and analysis within its monthly usage limit.
All paid plans currently include the same features; only the monthly analysis allowance and simultaneous roasting capacity differ.
Yes.
You can compare, search, and analyze uploaded roast data on the web, including viewing the flow of multiple batches on one screen.
Basic roast recording is available in the local environment.
Some web analysis, synchronization, and cloud features require an internet connection.
An authorized device can continue roasting during a temporary network interruption.
Data transmission is protected with HTTPS, and uploaded data is stored securely under your account.
See the Privacy Policy for details.
We continue to expand profile comparison, environment-based analysis, live flow guidance, collaboration, and sharing.
User feedback is actively incorporated.
Send questions or feedback through the /contact page.
User feedback also helps guide product improvements.
Understand the difference between signing in on multiple devices and roasting on devices at the same time.
Yes. You can sign in on multiple devices.
The number of devices that can roast at the same time depends on your plan.
Free / Lite: 1 device
Pro: 2 devices
Max: 3 devices
Yes. The Pro plan supports simultaneous roasting on up to 2 devices.
Up to 3 devices can roast simultaneously.
If device authorization has been confirmed, roasting can continue during a temporary network interruption.
Yes. You can sign in on multiple devices.
Signing in and roasting simultaneously are subject to different limits.
Signing in on multiple devices lets you view and edit records on each one.
Simultaneous roasting is the number of devices that can actively run a roast under one account at the same time.
Viewing, analyzing, or editing records does not count toward the simultaneous-roasting limit.
