 ### Board Battery Reporting
 
-- `get battery.reporting`: shows whether board battery reporting is enabled. Support is board-dependent.
-- `set battery.reporting on|off`: enables or disables battery voltage reporting on supported boards. This is currently useful for Heltec V3 boards where USB-only power can produce misleading battery readings. If your board needs this too, open an issue and support can be added board-by-board.
 - On repeater MQTT builds, background battery sampling used for MQTT/status history is rate-limited to about once per minute. Explicit status and telemetry requests still refresh the reading immediately.

+## Ghost Node Mode
+
+Ghost Node Mode is a convenience control on `/app` for a repeater that should stay on Wi-Fi and MQTT, but should not actively behave like another nearby repeater.
+
+Typical use case:
+
+- an indoor or colocated MQTT observer where another repeater nearby is already doing the RF relay work
+- a node you want feeding MQTT, web status, and troubleshooting data without also adding extra repeat traffic or adverts
+
+When enabled, Ghost Node Mode:
+
+- turns `repeat` off
+- sets `advert.interval` to `0`
+- sets `flood.advert.interval` to `0`
+- leaves the local web panel and MQTT features running
+
+When disabled, the panel restores the prior repeat and advert settings if it still knows them from the current browser session. If not, it falls back to:
+
+- `repeat on`
+- `advert.interval 60`
+- `flood.advert.interval 12`
+
+This mode is useful when you want the device to observe and publish, not to act as an additional RF repeater. It does not create a separate firmware role; it is just a grouped web-panel shortcut for those existing settings.
