A small gateway in Bluetooth range of the power station serves the dashboard over the van’s Wi-Fi: live telemetry, 30 days of history, and the controls that matter — the ports, AC charging and its limits, and every setting on the alternator charger.
Why
The vendor app routes through the cloud for things the hardware can do locally. Most of the test suite is regression tests for faults that actually happened on the hardware — a stale Bluetooth handle that connects but sends nothing, an extra battery that turned out to be the charger.
