Settings

The node's settings are under the System tab. This page covers the ones that change how scans behave. Feature-specific settings are on each feature's page.

Scan presets

A preset sets how long the node listens on each channel and how often it scans. Pick one under System → Settings → Scanning.

Preset	Time per channel	Wi-Fi scan every	Bluetooth scan every	Signal floor
Relaxed	300 ms	5 s	6 s	−80 dBm
Balanced (default)	160 ms	3 s	4 s	−95 dBm
Aggressive	110 ms	1.5 s	2 s	−100 dBm

Relaxed saves power and misses brief signals. Aggressive hears more and uses more power.

Signal filter and channels

• Signal filter: the node ignores devices weaker than this. Default −95 dBm. Change it in the web UI, or with @ALL CONFIG_RSSI:-80.
• Channels: which Wi-Fi channels a hopping scan uses. Default 1 to 11. Change them with @ALL CONFIG_CHANNELS:1,6,11.
• RF environment: how fast the node expects a signal to fade with distance, used by triangulation.

Mesh settings

• Heartbeat: the node sends a periodic status to the mesh. Set the interval or turn it off under Node & mesh.
• Cross-scan dedup: to save airtime, the node does not resend a device it sent in the last 5 minutes. Change it with @ALL CONFIG_DEDUP_TTL:<seconds> (0 to 3600). Alerts are always sent.

Battery Saver

Battery Saver stops scanning and sends only a heartbeat. Turn it on under Sensors & power, or with @AH01 BATTERY_SAVER_START:10 for a 10-minute heartbeat.
