🚀 Major Features

Advanced Miner Power Rail Automation System

Complete overhaul of the 12V and 5V miner power rail automation with intelligent multi-factor decision making.

New Features:

• Independent Rail Configuration: 12V and 5V rails now have completely separate automation settings
• Multi-Factor ON Logic: Miner rails turn ON only when ALL conditions are met:
  • Battery voltage ≥ user-defined threshold
  • Solar input wattage ≥ user-defined threshold
  • Conditions maintained for user-defined duration
• Smart OFF Logic: Miner rails turn OFF when EITHER condition is met:
  • Battery voltage drops below threshold (immediate)
  • Solar wattage drops below threshold for defined duration
• Persistent Configuration: All settings stored in EEPROM and survive reboots
• User-Friendly UI: Expandable configuration panels in the Controls page
• Prevents Power Cycling: Duration-based logic prevents rapid on/off cycling

Configurable Parameters (per rail):

Each rail (12V and 5V) has 6 independent parameters:

1. ON Battery Voltage - Minimum battery voltage to enable (default: 13.7V)
2. ON Solar Wattage - Minimum solar input wattage required (default: 15W)
3. ON Duration - How long conditions must be met before turning ON (default: 10 seconds)
4. OFF Battery Voltage - Battery voltage threshold to disable (default: 12.7V)
5. OFF Solar Wattage - Solar wattage threshold to disable (default: 10W)
6. OFF Duration - How long low wattage must persist before turning OFF (default: 10 seconds)

Default Behavior:

• Turn ON: Battery ≥13.7V AND Solar ≥15W for 10 seconds
• Turn OFF: Battery <12.7V OR Solar <10W for 10 seconds
