GridMind gives you complete visibility and control over your home energy system — solar panels, battery storage, EV charging, and grid interaction — all in one beautifully designed app. REAL-TIME POWER FLOW Watch energy move through your home in real time. An animated flow diagram shows exactly where your power is going — from solar panels to battery, home, grid, and up to four EVs simultaneously. Tap any node to drill into detailed metrics. SMART PEAK OPTIMIZATION GridMind's optimizer automatically manages your battery during Time-of-Use rate windows. It calculates the ideal moment to export stored energy to the grid at peak rates, maximizing your earnings while keeping your home powered. Track live progress on your Lock Screen and Dynamic Island. EV CHARGING INTELLIGENCE Monitor and control EV charging across multiple vehicles. See real-time charge rate, battery level, and estimated completion. GridMind tracks how much of your charging comes from solar vs. grid — down to the "solar miles" driven. FINANCIAL TRACKING Know exactly what your energy system earns. Track daily net value, export credits, solar savings, and import costs. Compare billing cycles, view hourly breakdowns, and watch your lifetime ROI grow. SOLAR FORECASTING 7-day solar production forecasts help you plan around the weather. See today's expected output, compare to tomorrow, and track how actual generation stacks up against predictions. ACHIEVEMENTS & GOALS Set daily targets for solar production, energy value, and carbon reduction. Earn achievements as you hit milestones — from your first solar kWh to your thousandth dollar saved. AI-POWERED INSIGHTS Machine learning monitors your system for anomalies and surfaces actionable recommendations. Ask follow-up questions to understand what's happening and why. HOME SCREEN WIDGETS & LIVE ACTIVITIES Glance at your energy status without opening the app. Widgets show solar output, battery level, and net value. During peak optimization, Dynamic Island displays live export rate and earnings. AUTOMATION RULES Build custom automation rules with a visual editor, or use preset templates for common scenarios like storm preparation and peak shaving.
