Monitor your battery system anywhere. BMS Monitor shows live state of charge, cell voltages, temperatures and power for your ESP32-based JK BMS setup — with home-screen widgets, Victron Cerbo, charger and SmartShunt summaries, and local over-the-air firmware updates. For iOS and Android.
Live state of charge, cell-level detail and energy summaries — plus firmware updates — from your phone.
BMS Monitor is the mobile companion to the SystemFreaks ESP32 JK BMS monitor — save your devices and open a live dashboard for any of them.
State-of-charge and state-of-health gauges, pack info and real-time power draw, so you always know how much is left and how healthy the pack is.
A per-cell voltage grid, temperatures and multi-BMS slot support surface the detail that matters when you're balancing or troubleshooting a pack.
See your Victron Cerbo GX, chargers and SmartShunt summaries right alongside the BMS, for a full picture of your solar and battery system.
Android widgets put battery SOC, power and status — and an energy summary of your BMS, Cerbo, charger and SmartShunt — on your home screen, refreshed automatically.
Update your ESP32 device's firmware over the local network straight from the app — no cables and no desktop tools required.
Built with Expo for iOS and Android (tablets included). Save several BMS devices and switch between their dashboards, with stale-data warnings so you never trust an old reading.
