Built for Hottop KN-8828 Series

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 Hottop-specific timing calibration built in. No drivers, no cables.

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 in v7.1, 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.
