Smart BMS Connect is an independently developed iPhone app for compatible RICN SMART battery systems. It connects over Bluetooth so users can scan nearby devices, connect, and view live data including state of charge, pack voltage/current/power, cell voltages, temperatures, and status. Supported home storage units also provide richer dashboards (including SOH, capacity, and cycle information where available) and an Actions tab for protocol read/write used in commissioning and maintenance. Bluetooth must be on; you need compatible hardware and firmware. Use only as described in your product documentation and local safety rules.
