v0.1.0

Key Features

Smart Cost Optimization

• Automatic Slot Finding: Analyzes today's and tomorrow's electricity prices to find the cheapest charging windows
• Grid Price vs Effective Cost: Shows both what you pay for electricity (grid price) and the actual cost per kWh in your battery (accounting for charging efficiency losses)
• Flexible Charging Windows: Supports multiple charging sessions (e.g., charge during 3 cheapest periods) or single continuous sessions
• Time Constraints: Set a "complete by" deadline to ensure your vehicle is charged when you need it

Interactive Controls

• SOC Slider: Drag to adjust your target charge level on the fly and instantly see the updated charging plan
• Complete By Controls: Click the time to expand adjustment controls with intuitive buttons (⏪⏴⏵⏩) for 15-minute intervals
• Visual Feedback: Color-coded slider shows different charge ranges (current SOC, target range, high charge, maximum)

Automation Integration

• Program Charging Button: Send the calculated charging plan directly to your EV or EV charger via Home Assistant scripts/automations
• Structured Data: Receives complete charging schedule with ISO timestamps, energy amounts, costs, and SOC levels

Charging Efficiency Support

• Account for Losses: Configure separate "energy in" (grid consumption) and "energy out" (battery charging) values to account for AC charging efficiency losses
• Accurate Cost Calculation: See both grid prices (what you pay) and effective costs (cost per kWh delivered to battery)
• Typical Efficiency: AC charging is usually 85-90% efficient; DC fast charging is 92-97% efficient
