Built for Hottop KN-8828B-2K+

Roast logging for your Hottop — no laptop at the roaster.

Only the 2K+ has USB, and most Hottop roasting still means Artisan on a laptop or a paper notebook. RoastSource runs on the phone in your pocket, with timing calibrated for the KN-8828B-2K+ built in. No drivers, no cables.

What RoastSource does for it

Timing bands calibrated for the KN-8828B-2K+ (the profile-driven KN-8828P gets general drum timing)
Works on a phone right next to the roaster — no laptop, no drivers, no USB required
Artisan user? Keep it — Artisan for the curve, RoastSource for everything else
Artisan .alog import coming soon — bring your roast history along and keep using both
Running a temperature probe? Home logs live temperature from a USB (Mastech) or WiFi (BounceBuster) probe, with real-time Rate of Rise
Green inventory, SCA cupping, and Roast Quality Score in the same app — plus blending in Journey and Science modes
Your data stays on your device — local-first, exportable, no cloud lock-in

Sound familiar?

“My model has no USB port”

Most KN-8828s don't — only the 2K+ does. RoastSource doesn't need one: log first crack, drop, and settings from your phone as they happen.

“A laptop next to a 400°F drum makes me nervous”

Leave it on the desk. A phone by the roaster captures the roast, and your log syncs nowhere unless you ask it to.

“Artisan logs curves — but where do my beans and cuppings live?”

RoastSource covers the rest: inventory, cupping, ratings, blends, and education. With .alog import coming soon, the two work side by side.

One app, from green bean to brewed cup

Inventory, roasting, ratings, blends, brewing, and coffee education — offline, private, and yours.
