I'm not that familiar with weather stations, so I'm not sure how good of a deal this is.

La Crosse has their wind + weather station on sale for $49. Comes with Breeze Pro Sensor (wind speed, wind direction, temperature, and humidity sensor) and display. Seems like the display was supposed to have WiFi but they goofed at manufacturing. The Breeze Pro Sensor (LTV-WSDTH01) is normally $69.95 MSRP.

Weather Station Display (79400) + Breeze Pro Sensor (LTV-WSDTH01) for $49: https://www.lacrossetechnology.co...1865688110

Just the display (79400-11) is on sale for $25: https://www.lacrossetechnology.co...s/79400-11 OOS

Cheapest shipping was $2.00 for me (FedEx - Smart Post).

Also on eBay ($49.95) with free shipping: https://www.ebay.com/itm/79400-La...4220049255

Edit: seems like it uses 915 MHz, so in theory you can buy it and a $20 RTL-SDR to get the data on your computer/Raspberry Pi/whatever. So for about $70 (the same price as the sensor itself), you get the sensor, the display, and a RTL-SDR dongle.

Quote from coachclass :
So, without wifi, does the entire left portion of that display become useless? That forecast panel wouldn't have any source material to draw from without a connection to whatever weather service it's using right? And the time and date would also be unavailable?

Please don't tell me the time flashes 12:00 12:00 12:00 all the time.
I bought this earlier in the year from the Instagram ad. You set the time and date locally, and it is saved in case of a power failure. I don't have it in front of me but all areas of the display are used, some panels of the display are kind of redundant but it accomplishes what I wanted - Outside Temp, Barometric Pressure, and Wind Speed.

The annoying flaw in the unit is a bright, flashing blue LED inside the unit that projects a pattern on the wall to the rear of the unit-- and never stops flashing. Maybe this is the WiFi sensor looking, I don't know. I had to cover up the rear cooling vent with a piece of electrical tape so it wasn't distracting in the darkened room. Frown

My bad, I guess they are $25 now for one without an antenna. But all the cheap ones are based on the same DVB chipset.

Bought, and set up.
The outdoor device has wind speed, direction, temp, humidity. Wireless. Feeds 3 displays from one outside device. Solar panel integrated, includes rechargeable battery.
Added rain sensor. The barometric pressure display spot can be set to alternate between pressure and rain every 7 seconds +/-
Display bright enough to see in a sunlit room. Not too readable outside in sunlight.
Viewing angle left/right is very wide. Vertical up to about 45deg, and only about 5deg below straight on.
Has a flip open stand on the back. I used that with a spring clamp to clip to the front of a high shelf. The display can be tilted down a little bit to allow easy viewing.

These were designed with wifi hardware, but it does not function. The manuals and menu references wifi - just ignore it.
It is a stand alone system that does not connect to the web.

You want to download the manual for all the parts you buy, and also the FAQ in the support site for them. Both together tell how to do things, and neither is complete alone. There are still some questions I have, such as how to clear rain gauge on demand, and other operations. Minor stuff.

When all displays were powered up initially, and left to sit next to each other a few hours, they all showed identical inside temperature and humidity. Very consistent calibration out of the box. No decimals on temperature numbers.

Mounting has 2 options for outside unit. There is a 5" piece the slips in horizontally. That mates to either of 2 other parts. One is about 9" and has a flat plate that can be screwed to a wall or another surface; or U bolts to a mast. The other is about 3" and is designed to slip onto a pole. These pieces connect together with a thumb screw to adjust from 0 to 90 degrees.

Overall very happy. It's not a tempest quality weather station, but for a fraction of that price, you get an actual physical display and save a pile of cash.

UPDATE - THREE FAILURES in less than a month

One display failed. Many numeric fields were missing several segments. LaCrosse promptly replaced it.

However, that replacement display has also failed. The display resets if unplugged for a few seconds. Backup battery is charged, but doesn't seem to work. Found it by trying to move it to a better location. Had to unplug for just a couple seconds, and poof... reset.

Another display has also failed. Randomly reboots causing all reading history to clear. But clock time is retained. Randomly shows impossible wind speed numbers too. (>100mph).

Now waiting on factory to address these 2 new problems.
Not too happy now. Considering returning the entire order for its lack of reliability.

Darn I was all in since I like to just look over and see what's going on outside. Here on my property not at the airport or 100 miles away. I did order it along with the rain sensor. BEFORE I READ all your posts. May return it. Not sure yet. Will see first. Will just cost me shipping back.

Does the rain sensor work with this w/o WiFi? Does it show on provided monitor?

Month later update...
LaCrosse sent replacement displays. All displays are now working.
Rain sensor stopped measuring rain. Found dirt\goop inside. Cleaned it and all good again.

Rain sensor talks to all units in parallel. Does not have (or need) wifi. This entire setup is operational as an island by itself. One wind\temperature unit, one rain sensor, several diaplays all show same sensor data. Each display shows it own indoor temperature.

Back to happy with it. lol

Do you have the LTV-R2 or the LTV-R3 sensor? I see the LTV-R2 is cheaper

Update: Will only work with the LTV-R3 Rain Sensor!
