La Crosse Technology308-1412-3TX-INT Wireless Weather Station (Including 3 Sensors) , Black

A surprisingly good design, 4.8 stars.For the main unit and three remotes, you will need 2 AA alkaline batteries each, 8 total.The deluxe: Accurate! Remotes match each other, and other devices.The remotes deploy easily. I attached the remotes to wood surfaces with #8 1¼ inch lath screws using the provided hole through the remote. You can also loosely hang the remotes on a #6 pan-head screw, but that is not secure in earthquake country.The battery door is accessible when mounted, so you don't need to take it down to change batteries. When set up properly, the base unit calibrates time to WWV exactly to the second, and matches internet time on the computers, so I can carry it around the house to set the other clocks.My remotes are deployed in the basement, the garage, and a northeast-facing corner in the back wall, just below the roof overhang. Now I know how warmly to dress before leaving the house, or raiding the freezer in the garage.The semi-deluxe: The main unit and the remotes are designed for a pair of 1.5V alkaline batteries. The "low battery" warning appears for 1.2V NiMH or NiCD batteries. The main unit draws about 0.4 mA. A pair of 2850 mAh Duracells should provide an estimated 7000 hours of operation (9+ months) between battery changes.The display is black on gray, a bit hard to read, but a backlight would mean more frequent battery changes, as would lower-capacity rechargeable batteries. The unit needs calibration and resynchronization after battery changes. I'm tempted to void warranties and add a socket for a wall wart on the main unit.Minor quibble: The humidity sensor "frowny face" ☹ appears when humidity drops below 40%. That is "standard" thinking, but some allergists recommend 35% to 40% indoors, and 68 to 70 ℉ in winter (wear a sweater) for respiratory health and control of dust mites. So ignore the frowny face, or choose a different LaCross-compliant allergist. This is a difference of opinion, NOT a design flaw - the design (and implementation) is suprisingly good.The outside sensor is fairly well protected from rain and sun by the roof and the high corner mounting, but I worry about rain and driving winds from the northeast. Perhaps the La Cross 925-1418 Sensor Shield will work, but the TX141TH-BCHV3 sensor is not specifically mentioned in the recommendations, and one of the Amazon reviewers says it does not fit. I will probably build my own weather shield ... and see if wasps build nests in it.

If you like to know the temps in 3 other areas, this works great. I have 1 in the greenhouse for the wife, 1 in the shop, and 1 inside the garage. Also a plus is the time is set by the atomic clock which helps when power goes out.

Bought this to monitor the temperature and humidity in a large, finished basement, and to that end it works well, with a few exceptions.1. Wish it came with an AC adaptor for the base/display unit. The 2 AA batteries last about a year, but not having to reset the unit and repair the sensors after changing them out would be nice too.2. One of the sensors was faulty, but the manufacturer replaced it without much fuss. (Replacements can also be purchased separately thru Amazon.)3. The black on gray LCD display is fine if you're standing next to it, but difficult to read from more than 3 feet away. Newer model weather stations have color on black displays which would be nice on this one. (I know its an older model...)4.Due to the base design, this can't be wall-mounted and remains a table-top only unit. Less than ideal, but not a deal breaker.Overall, this has be a great tool for monitoring different areas of my basement. I would recommend it if you are looking to monitor different zones in a building.

I have a heated garage some distance from my house and a basement shop that is heated only with a space heater when it's super cold out. This wireless gizmo allows me to keep tabs on everything from the comfort of my kitchen when the weather is really cold. It picks up the time and date by satellite so I always have the correct time and date, just in case I don't know the date . . . Like if I've been on a bender or something. It's also fairly attractive and unobtrusive on a counter or desk top. The temperature sensors are all within a couple of degrees and the humidity sensors are all within about 5% of each other. That's the best you can expect from one of these inexpensive units and really all you need.The only down side so far is that the display is not back lighted, so readability is dependent upon ambient lighting. Otherwise it's a clear enough display.

UPDATE: Guess I had a bad batch of batteries when I wrote my earlier review. Put in 2 new batteries yesterday & now it works fine again!Bought this unit in Nov 2021. Worked well until the last few days. The display got very dim when viewing straight on even when it is placed right next to me (not across the room). It's a little better if it is angled, but there is no means to do that without it tipping over. Thought it might need new batteries, but that didn't help any. There is no setting to adjust the brightness of the characters. Pretty disappointed.

Works as advertised, no back light so hard to read when dark. Seems to be accurate and all three sensors work.

This item works great but the moment it was tapped or knocked over it would lose all signal, although the batteries remained in the case and attached to the contacts. A small piece of cardboard placed in the battery compartment to tightly immobilize the batteries worked beautifully.

This weather station was exactly what I was looking for. It uses batteries so no trying to position it close to an outlet to plug it in. It was a breeze to set up and it works perfectly.

Con este sensor que se actualiza por RC, he dejado de actualizar la hora en mis relojes, de hecho, tengo 3 relojes de pared y 1 de pulso con esta tecnología y estoy muy contento con ellos, respecto a la temperatura y humedad también son muy exactos los sensores, tienen buen alcance los sensores transmisores, el mas alejado está como a 10 metros y sin problema lo detecta, lo recomiendo ampliamente

all 3 remotes were within an acceptable range of errori know its just more chinese junk with a "name " on it, but can only hope it lasts a while, unlike so much other rubbish out there

So far so good, the main unit display connects no problem to sensors outside and elsewhere in the house. Battery life has been fine through the summer, 2 months and counting without having to replace them.
