Intelligent Automation

Cheeky & Shoulder Charging

Set it and forget it with our custom energy arbitrage modes. Cheeky Charge intelligently dips into your backup reserve if it can to help you avoid expensive peak charges. Meanwhile, Shoulder Charge will maximize charging during the shoulder period to ensure you avoid peak costs entirely.

Grid Monetization

Tariff Cash-Out

Automate your battery to aggressively dump power to the grid during your most profitable pricing windows. Tariff Cash-Out dynamically compiles your custom TOU rates and respects your daily Tier 1 export limits, ensuring you maximize your returns without accidentally draining your home's backup reserve.

Immediate Control

Dual-Action Force Controls

Take absolute command of your energy storage with a single tap. Initiate a Force Charge to draw from the grid at maximum velocity, or a Force Discharge to dump your stored energy back to the grid during peak pricing. The UI features clear, directional loading indicators so you always know your system's exact state.

Clean Energy Focus

Forced Solar Capture

Take absolute command of your energy storage. Forced Solar Charge prioritizes clean energy capture regardless of your standard grid export rules, ensuring your solar generation goes exactly where you want it.

Economic Insights

Comprehensive Financial Tracking

arbi doesn't just track kilowatts; it tracks your wallet. View your precise energy savings and grid export earnings with granular breakdowns for Daily, Monthly, Yearly, and Lifetime metrics. Understand exactly how much your solar and battery investment is earning you over time.

Predictive Analytics

Advanced Solar Forecasting

Stop guessing how much power you'll make. arbi integrates geocoding and weather modeling to predict your Total Expected Solar for today and tomorrow. The dashboard continually updates your Remaining Now generation, helping you decide whether to run appliances or save power for later.

System Calibration

Sightline Clinometer

Accurate solar forecasting requires precise physical inputs. Use your device's built-in sensors as a Spirit Level & Clinometer to measure your roof pitch and panel angles. Our Sightline Method allows you to calculate these elevation angles safely from the ground, ensuring maximum forecast accuracy without ever needing a ladder.

⚠️ Safety First: Climbing on roofs poses a severe risk of injury; if direct roof access is required, we strongly advise hiring a licensed professional. When using ground-based sightline methods, you must maintain active situational awareness. Ensure you are standing in a safe, pedestrian-designated location completely clear of active traffic, roadways, and other environmental hazards.

Ultimate Privacy

Serverless Architecture

arbi operates entirely on your device. There are no middleman servers, no cloud databases, and no telemetry tracking. The app acts as the server, connecting directly to the Tesla Fleet API. This means your data, automation rules, and session tokens remain strictly on your local hardware, guaranteeing absolute privacy.

The Command Center

Intuitive Dashboard

Experience the most comprehensive view of your energy ecosystem. Our main interface provides a high-resolution, real-time power flow HUD. Monitor solar yield, battery health, and grid interaction with zero latency.

Live Monitoring

Near Real-Time Updates

Find out exactly what is using your power right now. arbi features adjustable real-time refresh rates, giving you a live, second-by-second look at your home's energy consumption so you can track down energy hogs instantly.

Smart Analytics

Precision Charge Timing

Know exactly when you'll be ready. arbi provides real-time estimates for Time to Full and Time to Empty based on your current home load.

Convenience

Always-On Command Center

Designed for dedicated monitoring stations. Enable Screen Always On to transform any device into a permanent energy terminal. Simply double-tap the dashboard to enter a focused viewing mode.

Professional Management

Multi-Site Monitoring

Manage your entire energy footprint by toggling between properties linked to your Tesla account. Use SHIFT + Left Click on Windows to launch independent windows for each site.

Data Intelligence

Deep Analytics & CSV Export

Your energy data belongs to you. arbi captures high-resolution historical graphs and offers one-click CSV Export to download your raw energy logs.

Live Telemetry

High-Resolution Data Logger

Capture every pulse of your energy ecosystem. Enable the Live Data Logger to record second-by-second telemetry—including granular power flows, battery states, grid interactions, and automation triggers—directly to your local device. One-click export allows you to pull this raw CSV data for custom external analysis.

Pro Tip: Look for the pulsing record icon on the main dashboard to confirm your live session is actively being logged in the background.

Elite Diagnostic

Battery Health & Degradation

Go beyond simple percentages. arbi performs real-time mathematical modeling of your Powerwall's chemistry. By analyzing continuous discharge segments (>15% drop), the app calculates your battery's actual usable capacity versus its factory nominal rating.

Pro Tip: Look for the health log at the bottom of the battery graph to see exactly how many kWh were used during your last deep discharge.

Universal Accessibility

Adaptive Across All Devices

Built on modern cross-platform technology, our responsive UI engine automatically adapts to any screen size—supporting seamless transitions between portrait and landscape modes.
