The eWS2300 editor connects directly to La Crosse WS-2300 weather stations via serial cable and provides low-level access to station memory. This allows reading raw sensor values, applying calibration offsets for temperature, humidity, and pressure, and exporting historical records that the station stores internally. The tool is useful for diagnosing sensor drift, verifying readings against reference instruments, and extracting data that the main GraphWeather application does not display. Multiple versions were released to address firmware differences across WS-2300 production batches.
