This Windows application will display and log weather data obtained through a USB connection to the Oregon Scientific WMR88, WMR100, WMR200 and RMS300 weather stations. You will find features here for a wide range of users, from novices, to experts. The extensive user manual describes program features in detail and includes informative discussions on many topics.

The display includes most of the data available on the console, analysis of wind and temperature data plus graphs of temperature, pressure, wind and rain over varying periods of time. Data is also logged to a CSV file with options for automatic backup and trimming. Daily extremes can be extracted from the log file and written to a separate CSV file. Data upload to Weather Underground and CWOP is supported. Web pages can be generated and uploaded to web servers through FTP.

The current stable version is 4.2 and there is also a beta version availabe which improves communications with the weather consoles and also adds support for WMR200 historical data. Warning -- the beta version may be a bit buggy, so proceed with care.


This application is designed to work with the indoor console receiving multiple outdoor temperature and humidity sensors and with or without the optional UV sensor. The following data is received from the weather station console and properly decoded:

* Temperature/humidity from the base unit and all wireless sensors.
* Current wind speed and direction.
* Average wind speed.
* Station pressure and altitude-corrected pressure.
* Current rainfall rate.
* Rainfall amount for the current hour and past 24 hours.
* Total rain since the last reset, and the date/time of the reset.
* Station clock setting & synchronization status with radio signal.
* Battery status (OK or Low) for console, rain bucket and anemometer.
* UV reading.
* Optional WeatherJack barometer can be used for higher resolution pressure readings.

WSDL can now handle the maximum number of external wireless temperature/humidity sensors. Custom names can be provided for each sensor and graph colors can be user-defined.

Up to 16 graphs can be displayed at one time, and each graph can display a different type of data and/or different set of sensors. Graph setups can be saved for later recall; you can create setups for different kinds of weather -- storms, heat waves and so on.

Data processing on the raw console data yields the following additional information:

* 15-minute rate of change for temperature and dew point (indoor and outdoor).
* 1-minute summary of wind data -- average and peak gust.
* Wind data processed according to METAR standards. Note: This DOES NOT mean you can legally use this software to produce offical aviation METARs.
* Peak wind gust over the past hour.
* 3-hour altitude-corrected (aka sea level) pressure rate of change.

The CSV-format log file is updated once a minute with the following information:

* Station and altitude-corrected pressure.
* 1-minute peak wind gust and direction.
* 1-minute average wind and direction.
* Rain rate and total rain since reset.
* UV reading.
* Temperature, dew point and relative humidity for all sensors.
