The roaster connects to the browser over USB. Each roaster gets its own screen; every roast curve is logged; recipes run automatically; a roast can be followed live from a phone. Supported: Aillio Bullet R1 (V1/V1.5/V2), TC4/aArtisanQ boards and other Artisan-protocol serial devices, a built-in simulator, or manual logging. Installable as an app and works offline. Free during public beta.
