## What is GenDash?

GenDash: Smart Generator Monitor

Real-time fuel 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 running on backup power:

"How much time do I have left before I need to refuel or recharge?"

GenDash combines your fuel level, real-time electrical load (watts), and environmental physics to provide a highly accurate, continuously updated Time-to-Empty countdown 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 exactly how it uses power.

• MASSIVE GENERATOR LIBRARY
Choose from over 100 pre-configured profiles with manufacturer specs, supporting standby units, portable inverters, and battery power stations. Have a unique unit? Enter custom specifications for total control!

• SMART HOME INTEGRATION
Connect natively to Home Assistant! GenDash reads live electrical load from panel monitors (Emporia Vue, Shelly, IoTaWatt) and smart plugs (Sonoff, Kasa). 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 selecting common appliances. From refrigerators and microwaves to coffee makers and phone chargers, GenDash 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 affects your remaining runtime.

• ENVIRONMENTAL PHYSICS ENGINE
Engines lose power at high altitudes and in extreme cold. GenDash automatically fetches local altitude and temperature to apply real-world physics corrections.

• LIVE ACTIVITIES & DYNAMIC ISLAND
Keep an eye on your generator from across the room. Your Time-to-Empty, fuel and battery gauge, and live load are always visible on your Lock Screen and in the Dynamic Island.

• TIME-SENSITIVE ALERTS & STALL DETECTION
Never wake up to a dead freezer. Set custom fuel alerts for 30 or 60 minutes before running dry. Use Time-Sensitive notifications to ensure urgent updates bypass focus modes. GenDash can even detect unexpected engine stalls and alert you instantly.

• GENERATOR MAINTENANCE LOG & TRACKING
Keep your engine running at peak performance. Track next due dates and engine hours for critical upkeep like oil changes, spark plugs, and valve checks. Log completed maintenance sessions with detailed notes to build a permanent service history.

• 100% PRIVATE & OFFLINE-FIRST
Your data belongs to you. GenDash requires no account, no cloud servers, and no subscription. Everything is stored locally. The core app works entirely offline when networks go down.

• A NOTE FROM THE DEVELOPER
I built GenDash because I needed it. During a power outage, I was tired of walking outside to check the fuel gauge or doing math on a notepad to see if my generator would last 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. No corporate bloat or hidden data harvesting—just a rock-solid, offline-first utility built for people who rely on backup power.

Whether you're managing a standby unit, a portable inverter, or a lithium battery station, GenDash ensures you stay safe and stay powered.

### 5/5 — Saved me during a storm

*2026-05-28*

We lost power last week and using this app helped us budget our fuel perfectly. I knew down to the minute when I needed to go back out and refill the tank. Incredibly easy to use even if you aren't a tech expert.
