A fast, lightweight PWA that controls your Crafty+ directly from the browser — no app store, no accounts, no cloud. Pure Web Bluetooth.

No more hammering a plus button. The circular gauge lets you drag directly to any target temperature. Boost and Superboost temperatures are calculated in real time and displayed as distinct markers on the arc — you always see all three reference points at a glance without navigating anywhere.
Create, name, and instantly activate presets that set temperature and boost together in one tap. Profiles are shown in a grid on the dashboard, so switching between your "Low & Slow" and "Full Flavor" sessions takes one tap and zero scrolling.
The official Storz & Bickel app exposes almost nothing. vo0t reads everything the device broadcasts:
- Runtime hours and total session count
- Power-on cycles
- Heater and battery diagnostics
- Serial number, firmware version, hardware revision
- All live characteristics over BLE in real time
Sessions are automatically recorded in local storage. Each entry logs start time, duration, and the temperatures you ran. Review your usage patterns without any cloud account or telemetry.
Everything the BLE protocol exposes, accessible directly:
- Target temperature, Boost, and Superboost adjustment
- Heater on/off toggle
- LED brightness
- Auto-Off timer
- Vibration on/off
- Charge indicator LED on/off
- Permanent Bluetooth visibility toggle
- Factory restart trigger
Fully client-side. Nothing leaves your browser. No accounts, no analytics beyond an anonymous page-view counter, no syncing. All profiles and session history live in your device's local storage.
Web Bluetooth is required and not supported by all browsers.

cd vo0t/app

npm run dev:simto start with a virtual Crafty+ device — no BLE required. The simulator heats up, drains battery, and responds to all controls just like the real thing. The connect screen shows a Simulator Mode badge so you always know which mode you're in. Click Pair new device as usual — the app connects instantly without a BLE picker. A floating SIM button (bottom right) opens the dev panel: override temperature, battery level, toggle the heater, or force a disconnect. Simulator code is completely excluded from production builds.
Open the localhost URL in a Chromium-based browser. For a production build:
npm run build
