v1.7.7

Fixed

• Stale scheduling_reason after turn-off – _turn_off() no longer leaves a stale cheap_grid reason on devices, preventing price-based turn-off logic from firing against manually-started devices.

Changed

• Preemption & shedding over-shed – Both the SD preemption path and the priority shedding path now run a two-stage algorithm (greedy + drop redundant) that avoids turning off more devices than the deficit requires while keeping low-priority-first shed order.

Added

• binary_sensor.aurum_cheap_grid_active – Exposes a global flag (ON while any AURUM device is running on cheap grid power) so external automations can block battery discharge, switch inverter mode, etc.
