The state-of-the-art La Crosse Technology WS-2811 Professional Wireless Weather Center features La Crosse's new state-of-the-art wireless "Instant Transmission" technology, featuring temperature and humidity data updates every 13 seconds, wind data every 17 seconds, and rain data every 19 seconds.

The La Crosse WS-2811 can monitor a number of weather variables including indoor/outdoor temperature and humidity, rainfall, wind speed and direction, and barometric pressure. The weather center also includes time and date display, weather forecast icons, and user-selectable alarm settings for a number of different weather conditions.

La Crosse's Heavy Weather Pro software allows you to use a PC to monitor and record weather data received from the WS-2811 via a proprietary USB device that's included with the weather station. You can monitor and record a variety of data collected by the various weather station sensors. You can also review weather history data, and analyze trends and tendencies over time using the software's charts and graphing features.

The WS-2811 comes complete with wireless indoor console, temperature and humidity sensor, rain gauge, and solar-powered anemometer.

Note: We do carry magnetic compasses to help you orient your anemometer to true north. Those can be located under the "Accessories" tab shown above. For more information on set up, please visit the anemometer page on our WeatherShack education center.

5 stars WS 2811
Product works as advertised. Easy to use and understand. Would rather have the 24 hr. rain measurement reset every midnight instead of the "rolling" method. A quality product.

4 stars Review One
Station works fine. I was not aware that this unit was a discontinued item when purchased. Although the instructions(?) suggested it, the units need to be powered up in a specific sequence. This is lame. PC display does not show any time display.

5 stars User friendly weather station
I was very impressed how easy the set up was. I have had many weather stations in the past and this station is easy to use compared to others. I work with high end $12,000 weather stations at work and this one other then being certified works just as well.

This weather station has been problematic almost from Day One. It simply stops working when it gets cold. No information gets transmitted. What's the point in having a remote thermometer if it doesn't register in cold weather?
By Gary

1 stars Does not transmit accurately
Easy setup but sensors do not function correctly with software provided. Rain gauge is essentially useless as it misreads constantly. Very disappointed.
By Thomas
From Fremont, CA
4 stars Overall, a very good weather station
A few recommendations are worth mentioning: The provided software (PC) download is outdated. I suggest providing something that syncs with MS Office Excel. This would enable far greater customization potential. The precipitation collector is quite difficult to mount. A more thoughtful/universal "mount" is in order. Placement of the battery cavity such at the side would be most useful. There is no back-light for the monitor. The monitor is a little too small. Recommend a form-factor of about 50% larger. The monitor does not indicate the date (day, month and year), and the clock is based on PC time. I'd go with a satellite update for the clock & date. Nevertheless, I think the system is one of the best available in the market place.

4 stars I will have fun with it!! Needs larger display.
Very nice unit, especially for the price. Easy to install and set-up. Weathershack page, service and support was very professional. Easy access. Everything I needed or questioned was on the page for the unit. It is apparent they cater to the customer before and after the sale. (5 Star)
