storz-rs

Control your Storz & Bickel vaporizers from Rust via Bluetooth Low Energy.

A Rust library for controlling Storz & Bickel vaporizers over BLE. Built on btleplug for cross-platform support. Protocol reverse-engineered from reactive-volcano-app.

Storz & Bickel devices

Supported Devices

Device	Tested	Notes
Venty	✅	Full support: temp, heater, boost, brightness, vibration, settings
Volcano Hybrid	✅	Full support: temp, heater, pump, fan, workflow automation
Veazy	🔬	Same protocol as Venty
Crafty+	🔬	Temp, heater, boost, LED brightness, factory reset

Venty and Volcano Hybrid have been verified with real hardware. Veazy and Crafty+ should work based on the shared protocol but haven't been tested yet. If you have one and want to help test, open an issue.

Quick Start

use std::time::Duration;
use futures::StreamExt;
use storz_rs::{connect, discover_vaporizers, get_adapter};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let adapter = get_adapter().await?;
    let peripherals = discover_vaporizers(&adapter, Duration::from_secs(10)).await?;

    let device = connect(peripherals.into_iter().next().unwrap()).await?;

    device.set_target_temperature(185.0).await?;
    device.heater_on().await?;

    // Stream live state updates from BLE notifications
    let mut state = device.subscribe_state().await?;
    while let Some(s) = state.next().await {
        println!("{s}");
    }
    Ok(())
}

Installation

API

Full docs at docs.rs/storz-rs.

discover_vaporizers() — BLE scan for S&B devices
connect() — auto-detect model, connect, run init sequence
VaporizerControl trait — uniform async API across all devices

Method	Volcano	Venty	Veazy	Crafty
`get_current_temperature`	✅	✅	✅	✅
`get/set_target_temperature`	✅	✅	✅	✅
`heater_on/off`	✅	✅	✅	✅
`pump_on/off`	✅	❌	❌	❌
`set_brightness`	✅	✅	✅	✅

`find_my_device`	❌	✅	✅	❌

pump_on/off returns UnsupportedOperation on devices without a pump.

Platform Support

Platform	BLE Backend	Status
Linux	BlueZ	✅
macOS	CoreBluetooth	✅
Windows	WinRT	✅

Requires a BLE adapter.

Troubleshooting

BlueZ needs permissions to start BLE scans.

Arch Linux — no bluetooth group, use polkit:

sudo tee /etc/polkit-1/rules.d/50-bluetooth.rules << 'EOF'
polkit.addRule(function(action, subject) {
    if (action.id === "org.bluez.Adapter.StartDiscovery" ||
        action.id === "org.bluez.Adapter.SetDiscoveryFilter") {
        return polkit.Result.YES;
    }
});
EOF

Debian/Ubuntu/Fedora — add yourself to the bluetooth group:

sudo usermod -aG bluetooth $USER

Log out and back in after.

rfkill unblock bluetooth
bluetoothctl power on
systemctl status bluetooth

Companion Client

Looking for a ready-to-use terminal app? Check out fumar — a TUI + CLI client built on storz-rs.

cargo install fumar
fumar           # TUI mode
fumar --cli status  # CLI mode
