LIVE DASHBOARD ⢠State of charge, voltage, current and power ⢠Remaining capacity, cycle count and temperatures ⢠Whether the battery is charging, discharging or resting CELLS ⢠Every cell's voltage, the spread between highest and lowest, and when the BMS is balancing ⢠A cell drifting out of balance is the earliest warning you get ā long before the battery lets you down HISTORY ⢠Readings recorded automatically while you're connected ⢠Charts of charge, voltage, current and temperature over hours, days or months ⢠Up to 90 days kept on the phone; export it all to CSV ALERTS ⢠Low charge, high or low temperature, winter guard and protection trips ⢠Set your own thresholds and quiet hours, so nothing wakes you at 3am MORE ⢠Multiple batteries and battery banks in one app ā see the whole system totalled, or drill into any single pack ⢠Tools for real installs: battery recovery for a pack that won't wake, connection diagnostics and a timestamped event log ⢠Report a problem in one tap ā the app sends Fogstar a full diagnostic bundle with a reference number, so we can help without the back-and-forth PRIVACY No ads, no tracking. Everyday monitoring is Bluetooth only ā your battery's data never leaves your phone unless you send a support report. Cloud features run on Amazon Web Services in Europe.
