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 All systems go
I was a little concerned as to if the wireless connectivity would cause any glitches, especially when the first two tries going through initial set-up did not have the different components linking. But the third try worked, and now have had 2 weeks of use. All the outdoor data is getting reported to the indoor display perfectly. Display is easy to read, very happy with the system.

4 stars Good instrument package
My previous LaCrosse 2310 was becoming unreliable in its old age. I liked the LaCrosse Brand for its quality and being inexpensive as my exposure is not great.

4 stars So far so good.
We tried this model based on reviews. We did not know it could control the weather let alone report it. Our last weather station never gave us a wind reading above 5 mph. This unit is same except for the past two weeks we have actually had almost no wind at all. It will be interesting to see if we can go all winter with no real wind.

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.

4 stars Definitely not a turnkey product
I had anticipated minor logistical problems with the location and installation, but it went quite well. I had not figured the component inter-phase would be so difficult. It took several trips up and down the ladder, and removing and replacing batteries to get everything in synch. Going to the website an downloading troubleshooting info was an important step. Once properly setup it's an amazing weather recording tool.

4 stars So far, so good
So far we are pleased with the product. We only have the temp./humidity meter up at this time but it is already helping us monitor both inside and outside temps and use our home environment resources more efficiently. This was my husband's birthday present and he had picked another brand and model weather station but upon reading the reviews I thought this was the better value. I'm glad I did a little research. Thanks! I only gave it four stars because we only have part of it up at this time.
