Module passive

Passive monitoring via BLE advertisements.

This module provides functionality to monitor Aranet devices without establishing a connection, using BLE advertisement data instead.

Benefits

• Lower power consumption: No connection overhead
• More devices: Can monitor more than the BLE connection limit
• Simpler: No connection management needed

Requirements

Smart Home integration must be enabled on each device:

• Go to device Settings > Smart Home > Enable

Example

use aranet_core::passive::{PassiveMonitor, PassiveMonitorOptions};
use tokio_util::sync::CancellationToken;

let monitor = PassiveMonitor::new(PassiveMonitorOptions::default());
let cancel = CancellationToken::new();

// Start monitoring in background
let handle = monitor.start(cancel.clone());

// Receive readings
let mut rx = monitor.subscribe();
while let Ok(reading) = rx.recv().await {
    println!("Device: {} CO2: {:?}", reading.device_name, reading.data.co2);
}
