Field notes
The page documents a sensor-to-map workflow rather than only displaying an alert badge. Its diagnostic layer tracks GPS, internal clock, ultrasonic sensing, electrical measurements, local storage, cellular modem status, MQTT connectivity, and signal quality. The interface also offers selectable telemetry windows from five minutes to seven days. At extraction time, several live values were blank, and the prediction module explicitly reported that it was not active.
