Ecowitt WS90 7-in-1 Weather Sensor, Outdoor Temperature/Humidity/Rain Gauge/Wind Speed and Direction/UV Index/Solar Radiation - Just Sensor, Could NOT Be Used Alone - 915 MHz

This unit replaces a ten+ year old Oregon Scientific station that over the last five years had steadily decayed. This HP2564 is far better in every respect. The package came with the WS90 all-in-one sensor ultrasonic anemometer/vane, piezoelectric rain gauge, light and UV sensor and thermo-hygrometer; the HP2560_C color display; a ring of bird deterrence spikes; and two paper manuals. The all-in-one sensor is compact and easy to set up. I installed two AA lithium backup batteries. I have it mounted on a PVC pole. I did not opt for the A/C heater module. I can't swear by the rain gauge, but it seems close to nearby station rainfall readings.The display is bright (brightness is adjustable) and easy to read. My unit is about 50 feet and two walls away from the sensor with all-bars on the WIFI icon lit up. It also comes with an interior thermometer and hygrometer, and micro-SD port, 32GB max FAT. The micro-SD card continually outputs readings in CSV format which are easy to analyze in Excel or similar spreadsheets and the card will take a long time to fill up. There is no battery backup (although the micro-SD card could be considered an approximation of same), so get a small UPS for the AC input if that's an issue. It's a little wonky to initialize, although the paper manual is adequate and online resources a little better. However, once you get used to the cumbersome sequential menu drill-down and value setting system (i.e., no touch screen nor direct go-to-setting shortcuts), it becomes quite usable. A cool feature is that if the unit is in a bedroom, it can be scheduled to go dark and then re-enable at certain times (or can be manually darkened and re-enabled at any time). This might also be useful to prevent long-term screen burn-in, but the manual does not say that's a problem with this kind of display.Setup of WIFI and communication with the optional internet Ecowitt.net service is straightforward. I have not tried linking to Weather Underground.The Android app is easy to use, showing current readings. It also shows graphs of various measurements over different time intervals, including yearly.At this point, my only fear is that as opposed to systems with separate sensors, with long-term use if part of the all-in-one sensor fails, then the whole thing must be replaced unless repair is possible. Otherwise, this is an excellent consumer-grade weather station.

Very satisfied. This replaces a tempest weather station. The Tempest did not accurately measure wind speed. Their customer support was terrible. This seems to work. It also configured itself more easily.

The outdoor sensor is very small and easy to mount. Setting up was easy including getting it on Weather Underground, Ecowitt weather page and Weather Cloud until the wind readings were questionable. The instructions are better than most Chinglish but not clear about calibration and wind direction. Attached is a downloaded, not included, diagram that made setting the direction obvious. The unclear instructions could have just said: "point the battery door north".The indoor temp was whacky until I found out the antenna isn't an antenna but the indoor temp sensor which must but up away from the display heat. The temp calibration is good as I checked it with a Fluke thermistor probe.You must calibrate the barometer. After several tries I got it tracking the local local airport well.I got rid of my Davis station because I was having trouble reading the displays. The Ecowitt display is easy to read and all info plus good graphs and history. .A problem was it was showing 1-2.5 mph when the wind was dead calm. I tried a sensor reset and calibration indoors while covered up. That didn't fix the problem but Amazon provided a replacement which was better. I did some inside testing. See attached.The touch buttons are annoying as after weeks I still tap the icons on the non-touch screen.The wind speed and direction updates slowly so as being a pilot it is hard to interpret what the wind is doing: definitely not like looking at a wind sock. The wind speed may be inaccurate, reads high with light wind and maybe low with higher winds.For $300 it is good OK but wish it had a touch screen and fast wind updates.

Ok, I have had this weather station for a couple of months now and I am ready to give it my honest review.I had an Accurite 5 in 1 weather station before this one and I like the Ecowitt better. With the app I can access my data easily and from anywhere. It is intuitive and easy to read. The unit is providing me with what I believe to be very accurate information on Temp, humidity,pressure and wind speed/direction. The rainfall gauge is reading higher than my additional standalone rainfall gauge. I have read in the manual that I can go into the setting and make corrections to adjust the offset but I have not done that yet. I do use the rainfall data to know when it rained and what rate. It is easy to see this information using the graphs.I also like the fact that this devise links up to Weather Underground and and is a part of a large network of personal weather stations. I got it linked up and when I am looking at the forecast on WUnderground I can also compare my weather data to other surrounding sites.I placed my WS90 sensor about 150 feet away from the HP2560 console and have no problem with connectivity and receive full bars of signal. I also like that the sensor has solar recharging so I won't have to change out batteries like I did with you Accurite 5 in 1 station.The HP2560 Console is a bit techy with all the function/setting buttons but the data display is easy to see and read and nice to look at. I find that the build quality is quite good on both the sensor and console. It was important to me when deciding on this personal weather station that the temp and humidity sensor is a replaceable module. My Accurite failed after a reasonable life of about 6 years. Being able to replace the sensor in this unit is a good feature.All in all, I give Ecowitt a thumbs up.
