ECOWITT Wittboy Weather Station GW2001, Includes GW2000 Wi-Fi IoT Hub and WS90 7-in-1 Outdoor Solar Powered Weather Sensor, Supports WU/WeatherCloud/Wow/Ecowitt Servers, 915 MHz

My wife gave me a Tempest weather station for my birthday, and to my disappointment it would never read the humidity correctly, being about 20 percent off other stations in my neighborhood or area.We sent it back for a refund and I decided to give this Ecowitt unit a try. I couldn't be happier! Setup was easy and the base station is excellent. It's customizable, you can calibrate the temperature, humidity levels, the barometric pressure, etc. This is a very useful feature.The best thing besides it working like a charm is all the other sensors you can purchase to use with it. Soil sensors if you are a gardener, air quality sensors to keep an eye on the air quality in your home, leak detectors so you have peace of mind, extra temperature sensors, etc. For the price it's a great product and I love the fact that sensors can be adjusted, changed, added, removed, etc.

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.

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.

Works great, should last a long time with no moving parts! Accurate right out the box, except for the rain gauge. There are inputs you can enter to make that more accurate!!!

I have had this unit in operation for about 6 months. I frequently compare my weather data to other close weather stations and submit my weather data to NOAA (via CWOP) for statistical analysis of the data. It is easy to set up and the software works well. However, ALL of the instruments are pretty inaccurate, and drift. It started with the Barometric Pressure, it is now very stable and accurate... after having to adjust the calibration by 5 millibars. The outside temperature is off by 3-5 degrees and drifts from reporting hot to reporting cold. The Humidity is lucky to be within 20%. The rain gauge reports rain when there is only drizzle and then way under reports any actual rain. You are better off just walking outside and seeing how the weather is.If they would incorporate accurate instruments I would love this thing... but they didn't... so I don't.
