- admin screen: telemetry via upstream LPPDataHelpers (ported; fixed its 1-byte humidity size), every field, per-channel, signed current (helpers/ui/telemetry_text) - battery %: both UIs show ZephyrBoard::getBattPercent() (discharge curve / fuel gauge) instead of a linear 3.0-4.2 V estimate - app/PowerPolicy: low-battery auto-shutdown + v-contact alert + autoshutdown CLI on every companion (headless too); under 2000 mV counts as no battery; default 3200 mV, stored 3300 migrated once - one time_sync.c for both UIs; ui_push_radio_state() for all roles - repeater admin screen in its own file; handleInput split per mode - dead UI code removed; companion help fits one reply frame

|
|
* with or without a UI: auto-shutdown (prefs.auto_shutdown_mv, `get|set
|
|
* autoshutdown`) and the v-contact low-battery alert (prefs.v_battery_alert_mv).
|
|
* Driven by the housekeeping tick, main thread only.
|
|
*
|
|
* Both sample the battery every 30 s and need three low readings in a row, so
|
|
* a TX sag cannot trigger them; both skip while the board reports external
|
|
* power. A reading under PowerPolicy::NO_CELL_MV is "no battery" (a board
|
|
* without a cell reads 0, or a floating divider), never a reason to act.
