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.

2 stars Problems with the wind instrument
I have had the instrument mounted and out in the sun since 3/23/16. I cannot get a reading from the wind instrument, even after getting instruction from Lacrosse (finally). I have had to contact them again, but it will be awhile before I hear from them again. I have had this same instrument before, purchased in 2007.

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 LaCrosse Complete Wireless Weather Station
Disappointed that it didn't come with any type manual. Also the fact wasn't stated that the product was a discontinued item.

4 stars 2811
I like the product but the instructions with the software is not intuitive. Maybe it's I, I do have a reading disability, but it seems that I can only call during my normal working hours, so there isn't much point. Oh yeah, not sure e why Alaska came up as my state, I live in Ohio

5 stars Bad weather
I give it 5 stars for the product itself. Well made and easy to set up and install. Unfortunately I could not make it work at my location. Did have to send it back to trade for another product. Customer service was quick to respond and take care of me.

4 stars New lacrosse weather station
This is my third weather station, but first Lacrosse. After downloading the manual from the website, putting it together was very easy. Assembling and mounting was very easy also as I already had a mounting post from previous weather stations. It might help if Lacrosse suggested something like 3/4" PVC pipe as a mounting aid though. Once it was mounted and batteries inserted the readings came quickly and seem to be very accurate. (we just experienced a 113 degree day so it got a lot of looks). The one problem I have had was that I could not synchronize the rain gauge to the monitoring display. I tried everything I knew and then asked fro support from Lacrosse. Their last response was to try a "factory reset". This finally corrected the problem. The rain gauge is reading. Sure wish it would rain to test accuracy! 105 today!!! If everything had worked at first I would have given it a 5!

4 stars Quick Look Display
This is my second La Crosse unit. My first one was a 2308 that has some good features as well and is still being used. When I say quick look I mean that you don't have to cycle through current stats by hitting the display button to get to the statistics you want to see. Indoor and outdoor temp on my old unit was one after another followed by the rainfall stats and so on. The new unit has it all on one display without having to hit a button unless you want to see min. or max. All the sensors on the new unit have improved plus the wireless ability is awesome and a must for us country dwellers. Doing my brief research before I decided to purchase the new unit I missed one detail, there's no back light which we really miss. For that it lost a star. The new one has a great refresh rate, nice and fast compared to older unit. I'm very satisfied with my purchase. La Crosse is into it, long lasting and keeping up with the times. I would buy again at the Weather Shack, my order was on its way practically over night and the shipping arrived earlier than expected and they allowed you to track it all the way. Totally hassle free and as expected. Thanks team.

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.
