GenDash: Smart Generator Monitor Real-time fuel and battery tracking, load monitoring, and time-sensitive alerts. Welcome to GenDash, your ultimate generator command center. Designed for power outages, severe storms, and off-grid living, GenDash answers the single most important question when you're running on backup power: "How much time do I have left before I need to refuel or recharge?" GenDash intelligently combines your energy level, real-time electrical load (watts), and environmental physics to provide a highly accurate, continuously updated Time-to-Empty countdown right on your iPhone, Lock Screen, and Dynamic Island. KEY FEATURES • REAL-TIME FUEL COUNTDOWN Stop guessing. GenDash dynamically calculates your exact burn rate. Whether you have a variable-speed inverter, a traditional constant-RPM engine, or a battery power station, our consumption engine knows how it burns power. • MASSIVE GENERATOR LIBRARY Choose from over 90 pre-configured profiles with manufacturer specs, supporting a wide range of traditional standby units, portable inverters, and modern battery power stations. Have a unique unit? Enter your own custom specifications for total control! • SMART HOME INTEGRATION Connect natively to Home Assistant! GenDash reads live electrical load from your smart home panel monitors and smart plugs. As your fridge cycles on or the AC kicks in, GenDash automatically adjusts your fuel countdown. • APPLIANCE LOAD LIBRARY Don't know how many watts your refrigerator or sump pump uses? Our new Appliance Library allows you to build a precise load profile by simply selecting common appliances. From space heaters to lights and home office gear, GenDash removes the guesswork and calculates your runtime based on what you actually have plugged in. • MANUAL LOAD BUDGETING Don't have a smart home setup? No problem. Easily log your wattage manually to "budget" your power and see exactly how plugging in an appliance will affect your remaining runtime. • ENVIRONMENTAL PHYSICS ENGINE Engines lose power at high altitudes and in extreme cold. GenDash automatically fetches your altitude and local temperature to apply real-world physics corrections to your fuel consumption. • LIVE ACTIVITIES & DYNAMIC ISLAND Keep an eye on your generator from across the room. Your Time-to-Empty, fuel gauge, and live load are always visible on your Lock Screen and in the Dynamic Island. • TIME-SENSITIVE ALERTS & STALL DETECTION Set custom fuel alerts that notify you before you run dry. • 100% PRIVATE & OFFLINE-FIRST Your data belongs to you. GenDash requires no account, no cloud servers, and no subscription. Everything is stored locally on your device. The core app works entirely offline when the cell towers go down. • PLAN BEFORE YOU PURCHASE Don't own a generator yet? GenDash doubles as the ultimate blueprint tool. Simulate highly accurate model metrics using manufacturer fuel-burn and discharge curves paired with our extensive Appliance Library. Know your exact runtime numbers before spending thousands on hardware. • A NOTE FROM THE DEVELOPER I built GenDash because I needed it. During a power outage, I was tired of constantly walking outside to check the fuel gauge or doing math on a notepad to figure out if my generator would last through the night. I searched for a proper telemetry tool and found nothing but basic calculators or subscription traps. So, as an independent developer, I built the tool I wanted to use. There is no corporate bloat and no hidden data harvesting here—just a rock-solid, offline-first application built for people who actually rely on their backup power. Whether you're managing a massive 22kW standby unit, a portable inverter for the RV, or a lithium battery station, GenDash ensures you stay safe and stay powered.
