21 customers mention21 positive0 negative

Customers are satisfied with the accuracy of the weather station. They say it is more precise with rainfall and temperature than the many AccuRite units they have. They also appreciate that it does not need calibration. The product is well worth the price and tracks the low and highs.

64 customers mention29 positive35 negative

Customers are mixed about the accuracy of the weather station. Some mention that it produces reasonably accurate data on outdoor temperature, wind speed, wind direction, rain quantity and the NWS forecast and chance of precipitation. However, others say that the wind/rain sensor became erratic and then failed, resulting in no valid weather prediction. Additionally, the humidity sensor provided inaccurate information.

"...of the station is that it does not take too much to make it not pick up the sensors. My wind/rain sensor is about 300' away, on a fence pole...." Read more

"...Rain amounts are easily traceable from one hour to one day to one week to one month to one year and total...." Read more

"Update. The rain and wind instrument is unusable. The battery terminals and wiring basically disintegrated. Not caused by battery leakage...." Read more

"...I also enjoy the NWS forecast and chance of precipitation that is shown at the top left of the display above the forecast icons...." Read more

55 customers mention18 positive37 negative

Customers are mixed about the connectivity of the weather station. Some mention that the wifi connection is easy and the data was showing up in less than a minute, while others say that it was never able to connect to their tri-band mesh router, the wifi indicator was a little confusing, and the time wasted trying to connect WiFi as directed was a joke. The main monitor randomly loses internet connectivity and takes forever to restore.

"Setup was challenging as the station would not sync with the NWS server at the time I received this product...." Read more

"...sensor type as "La Crosse" without any model number, and made the connection just fine, data was showing up in less than a minute...." Read more

"...Cons: WiFi fails with mesh networks, app is very buggy (see app store reviews for just how bad it is), leading ones in display are poorly formatted..." Read more

"...That said I like it. I was going to return it as it would never keep the correct time...." Read more

21 customers mention10 positive11 negative

Customers are mixed about the ease of setup of the weather station. Some mention that it works well and the app is awesome, while others say that it's a little tricky and needs improvement.

"...Cons: WiFi fails with mesh networks, app is very buggy (see app store reviews for just how bad it is), leading ones in display are poorly formatted..." Read more

"...The app is simple to use and quite impressive. I was able to label the location and type of each individual sensor...." Read more

"...App is a little trick but once set up is so neat. I use it frequently...." Read more

"...The app is getting better (more reliable) over time...." Read more

On Weather Underground in less than $250!
This model seems to have been discontinued on the La Crosse Technology site, unfortunately. I got a v21 just before the cold snap last month, and which was good, but did not go online to Weather Underground. So I made excuses to myself for being a geek, and got this one. Very happy overall. Love the display better than the competitors. The wi-fi set up was a bit of a bear, because I have a 2.4/5 GHz mesh network. But by just sticking with it, trying several times, it finally made the connection and worked. So then I was able to add a bunch more temperature sensors.Then came the Weather Underground set up. First, I set up a wunderground.com user account, all well and good. Then I applied for a PWS id, did all that online. Ran into problems when the V40 was not in the list of personal weather station models. So I selected "Other" and then completed the setup on the phone app, Weather Connect. And then nothing happened for over a day.... Not much help on line either. So I tried substituting different LaCrosse station models in the WU-PWS setup page, no luck.To get it working on Weather Underground, I had to delete the WU-PWS ID that I tried to set up on line, and do the whole WU PWS ID setup on my phone with their Weather Connect app, as a new weather underground Personal Weather Station. When I did it that way, it filled in the sensor type as "La Crosse" without any model number, and made the connection just fine, data was showing up in less than a minute. It also filled in the longitude, latitude, and elevation as well, so was well worth it, and very accurate to location.The main quirk of the station is that it does not take too much to make it not pick up the sensors. My wind/rain sensor is about 300' away, on a fence pole. And there is a couple of walls between it and the home station. So if an iPad or a flower pot is placed in the way at all, then it loses contact until I move them. I already relocated the T-H sensor to about 80' or so from the house, with a clear LOS between the sensor and the station. Will probably have to do the same with the Wind-rain sensor, which is more complex because it will need it's own pole, not just a handy tree.I also note that it occasionally is not connected when I first check the station in the iPhone wunderground app. But if I tap "retry" at the bottom of the screen, then it all fills in. Again, probably has more to do with me having the sensors fairly far away, and my family putting stuff close to the base station (the V40).But overall, other than the kludgy WU setup (that's on LaCrosse), I am very happy with it. Now I can monitor the temperature in my tractor barn, the wind and rain in my pasture, and the temperature and humidity in my fruit cellar. And see my own wind/rain/temp on Weather Underground, not somebody else's!The included picture is a screenshot from my Weather Underground PWS page.
