 ## Notes
 
 - Adaptive threshold varies by environment; 0.001-0.01 is a good starting range

+- NVS keys: `send_rate`, `tx_power`, `adaptive`, `threshold`, `ble_scan`, `target_ip`, `target_port`, `hostname`, `boot_count`
 - EVENT packets now include sensor hostname: `EVENT,<hostname>,motion=... rate=... wander=...`
 - ALERT_DATA format: `ALERT_DATA,<hostname>,<deauth|disassoc>,<sender_mac>,<target_mac>,<rssi>`
-- STATUS now includes `temp=`, `uptime_s=`, `csi_count=` fields

 - PROBE_DATA format: `PROBE_DATA,<hostname>,<mac>,<rssi>,<ssid>`
 - Probe requests deduped per MAC (default 10s cooldown, tunable via PROBERATE)
