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 is a great entry level weather station for getting extremely local weather information, and I love how it can be used on the local network, and even be blocked from external connections and still work, that's a rarity in today's tech world. I will say that I'm not so sure the rain gauge is accurate, BUT, if you have a normal rain gauge (I do not currently), you can take readings, compare, and alter the rain gauge on the local webpage for the hub to help it be more precise. It easily integrates into Home Assistant, and plenty of scripts can be written for it, like in the second picture in this review. Every sensor highlighted is straight from either the weather station or the included hub, but the ones not highlighted are calculated custom template sensors I added. The 'Feels like' temperature takes the wind speed and current temperature into account for wind chill (not 100% accurate, but I bet it could be if I included the sunlight/”radiation” into the equation), or it will take the temperature and the humidity when applicable and calculate the heat index. Still have yet to try the latter out, as it is a bit cold here at the moment, but looking forward to testing it out this spring. The 'Fire risk' takes the rain average over the last 10 days (default data storage for home assistant – haven't changed it), the current humidity, and the temperature into account to calculate the current fire risk. I am still learning, but this is all with sensor data that this weather station can output! Looking forward to doing more with it, and if you have smart lights, you can make a sliding scale for how bright they may be based on the sunlight the weather station is receiving, etc. Nearly endless possibilities. The hub itself supports much more than just this weather station, and we currently have three Ecowitt thermometers connected to it with no issues. Also looking forward to expanding our Ecowitt device collection and doing more home automation with them, too! Side note - if you are wanting to power your weather station via normal power, or use the heater, the cable for that is not available on Amazon (At least it wasn't for us at the time of purchasing), and it was quite pricey.

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.

Fits on a 3/4” PVC pipe securely and makes it easy to mount anywhere. Used two hose clamps to attach it to a roof vent. Just align North as indicated (and I did attach the included bird-repelling wires,) and it’s good to go. Had a series of rain events over the weeks since installed and the results closely corroborate with the local weather station reports. Wind indicator is clever and seems to be accurate. The trendline reports on the app are great - terrific performance from a compact and economical instrument. Solar power is a plus, and the app indicates charge level.

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.

I recently purchased the Ecowitt WN32(WH32) Wireless Outdoor Temperature and Humidity Sensor, along with the WH31 Indoor Sensors and the Ecowitt GW2000 Wi-Fi Hub. These devices were recommended on some Home Automation Forums, and they don't disappoint. First and foremost, reliability is a key factor when it comes to temperature and humidity sensors, and the Ecowitt sensors have proven to reliable. Once paired with the hub, they update frequently, much more often than battery-operated devices running on zwave or zigbee networks. In the past, these other sensors would simply stop reporting, or update only every 10-15 minutes. These update approximately every 60 seconds so I always have access to the most up-to-date information. The app also provides a handy graph or chart displaying the historical temperature data, allowing me to monitor trends and changes over time. I am using this to help hone in my HVAC system, and know the temperatures of different rooms around the house. Setup was easy - just select the channel, go into the App for the Hub, and it will detect the device. From there, you can setup the name, order in the app, and view the data. While the Ecowitt sensors can function perfectly well as standalone products for monitoring temperature and humidity throughout the house, I opted to integrate them into HomeAssistant so I can now leverage the data in automations and display it on customizable dashboards, adding an extra layer of functionality. It's worth noting that the Ecowitt GW2000 Wi-Fi Hub does have some limitations regarding the number of devices it can accommodate. For the WH31 Indoor Sensors, the hub supports up to 8 devices, which is more than sufficient for my needs. However, for the WH32 Outdoor Sensor, I believe only one device can be connected per hub. It's essential to review the hub documentation before making a purchase to ensure it meets your specific needs and device requirements. You could also purchase another hub to pair more devices - Each of them have a channel select in the battery compartment which is how it registers to the hub. In the future, I may also bring in their soil sensors for better lawn care as well. Current Devices: - GW200 Hub, Wired (Can also use Wireless) - 1x WH32 Outdoor Sensor - 5x WH31 Indoor Sensor

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.

The primary reason for a weather station is for temperature, humidity, wind and RAINFALL. I’m not sure about the accuracy of the first three factors but I guarantee you that the rainfall accuracy is in the TOILET! I now have 4 rain gauges. Last night it rained. Here are the readings of all four. Ecowitt WH40BH .19 inches: AcuRite 01014M .16 inches: Stratus manual gauge .18 inches: ECOWITT WITTBOY PRO .75 inches I already had the AcuRite for many years. I just got the other three. I bought the Stratus and the WH40BH to compare accuracy. Don’t buy the WITTBOY. Instead get the display and other wanted components individually and create your own station. Just had a storm. The NWS issued a severe thunderstorm warning with high winds. This thing showed 13.4 mph as the highest. Way off. Actual rainfall was .50 inches. WS90 showed 1.10 inches . Now wish I hadn’t bought it! I do like the display. I’m gonna trash the WS90 and buy separate components to use with it. I am not returning it to Amazon, it is not their fault. I should have trusted the negative reviews.

I’m really liking this weather station. It was very simple to get up and going. I connected and registered the gateway and once I added batteries to my sensors, the gateway instantly adopted them and I was able to see the sensor data. The gateway is about 150ft away from the weather station in a straight line. The signal has the pass through a brick wall and two interior walls. The gateway reports a strong signal to my weather station’s mast and lightning detector. I’ve got my station up and going and it is feeding live data to Weather Underground.
