The Ecowitt GW2001 combines the GW2000 Wi-Fi and Ethernet gateway with the WS90 7-in-1 outdoor weather sensor. The bundle measures outdoor temperature, humidity, wind speed and direction, rainfall, UV, and light, while the GW2000 receives the sensor data and provides Wi-Fi, Ethernet, Ecowitt.net, and local integration options. It is a practical choice for buyers who want a complete Ecowitt weather station without assembling the gateway and outdoor sensor separately.
Specifications and compatibility notes are based on manufacturer documentation — not independent Atmosiva testing.
Known limitations
- •Amazon listing for this page is the GW2001BU weather station bundle (GW2000 gateway + WS90 outdoor sensor array + bird spikes). The GW2000 alone is a gateway and does not measure outdoor wind or rain by itself
- •WS90 normally requires a compatible Ecowitt gateway or console — the gateway is included in this GW2001 bundle
- •915 MHz is the US-region version sold on Amazon.com; regional RF frequencies differ and must match any add-on Ecowitt sensors
- •WS90 uses haptic/piezo rainfall sensing; buyers who prefer more traditional rain-gauge behavior may add a WH40 depending on use case
Expansion options
- •Additional WH/WN Ecowitt RF sensors on supported channels
- •Multiple WH51 soil moisture channels on supported firmware — retail/docs for GW2000 commonly cite up to 8; confirm current Ecowitt channel charts for your firmware
- •WH57 lightning, WH41/WH45 air quality, and other Ecowitt add-ons
- •Optional WH40 traditional rain gauge if preferred over piezo-only rainfall
Pros
- + Complete bundle: gateway + outdoor sensor
- + Ethernet and Wi-Fi connectivity
- + Compact WS90 with ultrasonic wind sensing and no moving wind cups
- + Local integration options for Home Assistant
- + Expandable Ecowitt sensor ecosystem

Cons
- − No dedicated display console included
- − WS90 rainfall uses haptic/piezo sensing rather than a traditional tipping-bucket gauge
