Funcional

This device is as good as a barometer alone can be. Meteorological predictions are based on many parameters, and the barometric pressure is only one of several parameters to monitor. A barometer will always miss the other parameters, therefore being a limited weather prediction tool. Still, 13 or so different eye-catching icons provide a whealth of possible weather predictions for the next 3 to 9 hours (not 24 at all). The viewing angle could be considered as somewhat narrow by some users, but that's the nature of LCD technology, not a design flaw. It's perfect when viewed slightly from below eye level. The vivid colours and the 3-level background lighting are wonderful. Be aware that in order to use the background lighting on a long-term basis, the use of the provided power supply is mandatory. Full daylight will dime the visibility of the screen content, just get closer to it. As an awesome added feature, this model (along several other ones) allows the measurements to be calibrated, which adds even more precision to the readings. For me, the only thing missing is the name of the days, like Mon, Tue, Wed, etc. I would buy another one and I recommend it.6+ months reviewStill loving it! : )

Muy buen producto, buena presentación y funcionamiento

Al momento está funcionando muy bien. No le pongo 5 estrellas por que acaba de terminar su período de aprendizaje y al momento a hecho predicciones de lluvia en dias con sol. Sin embargo la medición tanto interna como externa es adecuada y la transmisión inalámbrica funciona muy bien.

The outdoor temperature accuracy is off by about 4 degrees, but as another reviewer mentioned, the company states right in the manual that this is "acceptable variance". The good news is it's always off by 4 degrees, so we know it's always 4 degrees cooler then the sensor says.The connectivity of the outdoor sensor and the indoor display is great! We live in a mobile home with metal siding,and have problems using our cell phone and other wireless devices sometimes, but have not had ANY issues with this. It's actually pretty amazing.It doesn't measure wind speed. It doesn't claim too, but for some reason I thought it would. I was pretty disappointed that it doesn't, but that was my inability to read. Just thought I'd mention it, in case anyone else might think the same.It's weather predicting is right about 60-70% of the time. It seems to think we're going to have thunderstorms all the time...we haven't had a thunderstorm since we bought the unit like 5 months ago. But it's right more than not.It seems to be holding up pretty well. I don't see it breaking anytime soon. I'd recommend this if you don't expect too much accuracy, and use it as more of a guideline, you should be pretty happy with it.

When I was looking for an indoor/outdoor thermometer there weren't a lot of reasonably priced units that were wireless and had a logical display layout. Many displayed the time in larger characters than the temperatures I was mainly interested in. Few were in color and most were criticized as being inaccurate. I settled on the Acurite 02027A1 because of it's well designed screen layout and reasonable price with the hope that it was somewhat accurate and had decent wifi range. I initially installed the outdoor sensor on the north side of the house under the eave and attached it with velcro. I was getting 4 bars of wifi reception and allowed it to complete its 14 day learning cycle. Indoor temperature and humidity readings agreed with an older analog unit I had and the barometer was consistent with the nearby airport readings. The outdoor humidity readings seemed reasonable but the temperature was high, sometimes by 10 degrees F. I found the effect to be more pronounced on sunny summer than winter days even though the sensor was completely shaded at all times. I suspected the sun was warming the building structure and the sensor was picking this up so I tied a string to it and hung it from a bird feeder post I had near the edge of the woods. This location was mostly shaded but had good airflow and was not close to any structure. To my surprise the temperature readings lowered and were within a degree or 2 F of the nearby airport. The humidity readings also correlated much more closely especially on the high end which before rarely got above 90%. I have since purchased an Ambient Weather radiation shield for the outdoor sensor and have continued to obtain accurate temperature and humidity levels. Another surprise was the accuracy of the forecast. With a few exceptions it accurately forecast rain/snow 6 to 12 hrs before it occurred. It is sometimes fooled by popup summer rain showers but not usually by weather fronts. I have been using it now since February and have had no problems. I have found the old adage location, location, location to be the deciding factor for accurate readings when placing the outdoor sensor. I have about 80ft of separation between the indoor and outdoor units and consistently receive 4 bars of wifi signal and have never had dropouts or frozen readings that others have noted. For what I have seen currently available, this thermometer will not disappoint.

Just received the AcuRite 02027 WX station today and it was easy to set up. Took about 15 min total to get it up and running, and that included mounting the remote sensor underneath my back deck. I mounted it on a flooring support cross beam, approx. 5.5 ft above ground and 9 ft out from the house. In this location, the sensor gets adequate protection from the elements, is completely shaded all day and gets good air flow. No problems with data transmission as well thus far. I have 5 bars of signal strength indicated on the WX station screen and the sensor transmits at exactly every 16 seconds (red light on the remote sensor flashes when it transmits). The station itself is very easy to program. Instructions are easy to read and follow. After starting the unit up, I spent about an hour online pinpointing a dozen nearby professional-grade Personal Weather Stations - "PWS's" (see wunderground.com, search by zip code) so I could get a geographical baseline on air temp, RH and barometric pressure readings for my neighborhood. After manually adjusting the readings on the WX station to match the local PWS's, I sat back, watched and waited. I checked it against the local PWS' obs every 30 minutes or so for almost 9 hours. So far, the WX station readings are right in step with several PWS's in my vicinity (1/4 - 3 miles distance from me). As far as indoor temp and RH readings, the unit is pretty accurate IMO...as I bench-marked the indoor temp and RH with an older WX station I have, as well as against a couple of reliable mercury thermometers I have hanging here in the basement.All in all, this unit is very well worth the price as far as I can tell so far. I'll provide a follow-up to this review in a couple of weeks once the self-calibration ("Learning mode") for the barometer is complete.09/29/2015 Follow-up;Still very pleased with the performance of this WX station. The "Learning Mode" calibration period ended at 2 weeks and my barometric pressure readings have been spot on compared to several nearby online PWS's. Outdoor Temp and RH are very accurate and again match very closely with nearby airport METARS and PWS's. I have been so pleased with the accuracy of this station, that I bought a second unit for my living room upstairs. I am running that unit off the same remote sensor I am using for the original unit (just had to make sure the new unit was set to the same channel as the sensor is set to). So now I have 2 of these stations in my house...and both are displaying the exact same outdoor temp, RH and pressure. Obviously the indoor temp and RH readings are slightly different between the two as one is in my basement office and the other is upstairs in the living room. Moon phase feature has been accurate and the clock is surprisingly precise so far...+/- 2 or 3 seconds when checked against shortwave radio time stations, WWV (US-10.000 mHz) or CHU (Canada-14.670 mHz).I am thinking of getting a 3rd station...for my night stand....but will have get approval from my wife before doing that!!Update 11/18/2015:2+ months after purchase and this weather station is still spot-on with it readings; indoor and outdoor. Regarding the outdoor readings; temp, RH, barometric pressure and tendency are still almost exactly in step with the two nearby airport AWOS reports I benchmark against. The clock has been very consistent as well (still holding at +/- 3 seconds accuracy versus the NIST shortwave radio time clock). I did end up moving moving the outdoor remote sensor to another part of the cross beam underneath my back deck. The original spot turned out to be on drip line for water...so the sensor was getting wet in heavy rains. The new location, only 2 feet to the left, has proven to be a much drier spot and free of heavy drips.
