ECOWITT Weather Station GW3001 — GW3000 Wi‑Fi & Ethernet Gateway with WS90 7‑in‑1 Sensor, SD Card Port

The ECOWITT GW3001 is a complete home weather station kit that pairs the GW3000 Wi‑Fi/Ethernet gateway with the WS90 7‑in‑1 outdoor sensor array to deliver local temperature, humidity, wind, rainfall, barometric pressure, solar/UV and indoor conditions to apps and custom services.

This kit brings together ECOWITT’s GW3000 gateway and the WS90 outdoor sensor array so you can collect, view and share detailed local weather data. The gateway includes an internal temperature/humidity sensor, barometric pressure sensor and an SD card slot for local logging, while the WS90 combines multiple outdoor measurements into a single IPX5 weatherproof unit with a built‑in solar cell for power assistance. Data can stream to the Ecowitt app or be forwarded to third‑party services via Wi‑Fi or wired Ethernet.

How does this system collect and transmit local weather data?

The WS90 consolidates sensors for temperature, humidity, wind speed/direction, piezo rainfall, UV and solar radiation and sends readings over a 915 MHz RF link to the GW3000 gateway. The gateway then uploads data to the Ecowitt cloud and compatible services via Wi‑Fi or an Ethernet connection, and also stores logs on a FAT32 SD card for redundancy.

• WS90: 7‑in‑1 outdoor sensor array with IPX5 waterproofing and solar panel.
• GW3000: internal temp/humidity and barometric sensors plus SD card port (up to 32GB).
• Transmission: 915 MHz RF, up to ~300 m (1,000 ft) open range, ~150 m (500 ft) with obstacles.
• Connectivity: Wi‑Fi or Ethernet upload to Ecowitt, Wunderground, Weathercloud, WoW, HomeAssistant, etc.

What installation and configuration should I expect?

Setup is designed for DIY installation: mount the outdoor WS90 where it has clear exposure to wind and rain, place the GW3000 indoors near your router, then configure network settings in the Ecowitt or WS View Plus app. The gateway supports both wireless and wired network setups, and you can calibrate or add sensors from the app interface.

• Mounting: recommended clear exposure for accurate wind and rainfall readings.
• Network: Wi‑Fi setup via app or plug GW3000 into router with Ethernet cable (not included).
• App control: manage calibration, sensor selection and upload targets in the Ecowitt app.
• Local backup: record to a FAT32 SD card (up to 32GB, SD card not included).

Which measurements are provided and how reliable are they?

The WS90 measures outdoor temperature and humidity, wind speed and direction, UV and solar radiation, and records rainfall using a piezo sensor for fast response to light showers and heavy downpours. The GW3000 adds indoor readings and barometric pressure so you can monitor both inside and outside conditions from one dashboard.

• Outdoor: temperature, relative humidity, wind speed/direction, UV, solar, piezo rainfall.
• Indoor and pressure: GW3000 includes indoor temp/humidity and barometric pressure sensors.
• Power/reliability: WS90 solar panel assists power; IPX5-rated housing for weather resistance.
• Range considerations: RF performance varies with obstacles—test placement for best signal.

Who is this for? The ECOWITT GW3001 is well suited for homeowners, small farms, hobby meteorologists and smart‑home integrators who want a compact, networked weather station that feeds both local logging and online services. It’s practical for anyone who needs multi‑parameter outdoor readings and flexible upload options (Wi‑Fi or wired Ethernet) without the cost or complexity of larger professional systems. Note: additional ECOWITT sensors and IoT accessories can expand the system but are sold separately.
