The Ecowitt Essence3 colour weather station is a bright 7.5" LCD large display Wi-Fi  enabled weather station which supports monitoring both indoor and outdoor conditions.

It is also one of the first consoles to support connection to the Ecowitt IoT devices, such as the Ecowitt WFC01 and AC1100, achieving smart control through the Ecowitt App.

The WS3900 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 WS85 3-in-1 sensor array which transmits wind speed, wind direction and rainfall to the console. The sensor array also includes a solar panel to power the unit during daylight and extend the battery runtime.  Along with the WS85 is the WH32 outdoor temperature and humidity sensor which can be placed in a location away from direct sun and sources for moisture for improved readings.

Unlike some other weather stations, the Ecowitt Essence3 can be used with a variety of additional sensors, click here to view the latest Ecowitt sensor matrix  and also view further details of which sensors are visible on the screen in the Technical Tab above.
