The dashboard has a hidden diagnostics overlay. Tap the top status card five times within roughly three seconds to open it. Double-tap the diagnostics overlay to return to the main dashboard.
The overlay also provides the initial XIAO sensor-node bring-up view. The dashboard receives newline-delimited JSON through its onboard automatic-direction RS485 transceiver on GPIO43 RX / GPIO44 TX at 115200 baud. It shows link age, received/dropped/error counts, IMU pitch/roll/accuracy/stability, and GPS fix/satellites/HDOP/location/speed. Cargo communication remains WiFi/HTTP through `/api/v1`.
The diagnostics overlay shows dashboard version, uptime, heap, WiFi RSSI/IP, Cargo API status, Cargo firmware version, Cargo uptime, Cargo heap, Cargo AP client count, BMS status, relay count, and basic control-loop state.
