./adaptive_controller_manager.sh start|stop|restart🌅 Sunrise/Sunset Optimization: The system uses intelligent sunrise/sunset scheduling with geographic awareness for optimal energy efficiency:
- ~90% energy savings vs continuous running - only activates during light transition periods!
- Dynamic activation windows - 30min before to 2h after each sunrise/sunset (automatically calculated for your location)
- Geographic intelligence - auto-detects coordinates or uses manual configuration
- Seasonal adaptation - windows automatically adjust as days get longer/shorter
- Optimized flash detection - 40-second wait then compares with saved state (>40% change threshold)
- Eliminates unnecessary activations outside natural light transition periods
- Fallback protection - reverts to time-based logic if sunrise/sunset calculation fails
