The Ecowitt WS3801 is a mono screen weather station and the WS3901 the colour equivalent. Both weather stations have a large 7.5" LCD display with Wi-Fi and display both indoor and outdoor conditions.

These are some of the first consoles to support connection to the Ecowitt Internet of Things (IoT) devices, such as the Ecowitt WFC01 and AC1100, achieving smart control through the Ecowitt App.

The console connects to your 2.4GHz Wi-Fi network for viewing uploaded data from anywhere on your phone, tablet, or computer browser, all for free when uploaded to Ecowitt.net

The display has built-in temperature, humidity and barometric pressure sensors receiving readings from Ecowitt sensors on the 868MHz frequency.

Included is the WS90 7-in-1 sensor array which transmits sonic wind speed & direction, haptic rainfall, UV, solar radiation, temperature and humidity to the console. The 7-in-1 sensor array also includes a solar panel to power the unit during daylight and extend the battery runtime.

The WS90's unique design no longer uses the traditional tipping bucket rain gauge, but a haptic sensor which measures rainfall. The revised rainfall sensor is slightly sloped to improve accuracy and prevent rain pooling and also includes rain start detection before any measurable rain has fallen.

WS90+WS3901 combo

After one week, I am pretty happy with this Weather Station, not least because I am back on Weathercloud, so can easily see my own info on any web connected device as well as even more info on the console.
Set up using the very comprehensive manual was not very easy, but was somehow successful.
Really a native English speaking expert needs to write 'setup notes' related to users operating software (in my case Win 11), which did not seem to have the same responses as shown in the manual, whose B&W printing was rather indistinct; but I hacked my way through the manual to get going. Though it appears to me the console allows many more presettings than I have already found!
Amusingly, I immediately missed a physical wind speed and direction indication that I can see on the pole, so have installed an old pair not connected but just to look at...

WS90+WS3901 combo

7.5" Colour (WS3901) / 868MHz UK/EU

A great little device!

This unit is great for a small footprint, and very accurate. It comes well packaged and paired with the screen with ease, the only thing you need to supply is two AA batteries and the one inch pole (standard TV aerial one) the wind direction monitor is surprisingly good compared to the traditional type which tend to fail over time. Just download the Ecowitt app and follow the printed manual in the box (FULL SIZE MANUAL) and your up and ready to setup to use!. On a side note the customer service here is outstanding and replied to my questions within the hour.
