ECOWITT GW1100 Wi‑Fi Weather Station Gateway — 3‑in‑1 Temperature, Humidity & Pressure Probe

Meet the ECOWITT GW1100 Wi‑Fi Weather Station Gateway

The GW1100 serves as the central hub for a connected weather setup, pairing a built‑in 3‑in‑1 probe with a versatile gateway design. With a 1.5 m USB extension included, you can power the gateway where readings matter most and position it for stable signal and easy access. This combination helps you capture precise temperature, humidity, and atmospheric pressure data in real living spaces or outside in a sheltered spot.

Compared with older gateways, the GW1100 simplifies Wi‑Fi configuration, getting you connected quickly and ready to start tracking weather trends. When you want to keep pace with evolving needs, you can choose automatic firmware updates, or opt to keep your current setup while updating manually. Your historical data remains accessible, even if you decide not to auto‑update.

What you can monitor and connect

The GW1100 is designed to work with a broad ecosystem of Ecowitt wireless sensors, sold separately. It can pull data from outdoor sensors such as WN32 (WH32), rainfall sensors like WH40, wind instruments such as WS68, and multi‑channel temperature/humidity sensors (up to 8 WN31/WH31). It also supports soil sensors (up to 8 WH51), PM2.5 air quality sensors (up to 4 WH41/WH43), air quality indicators (WH45), water leaks (WH55), and lightning sensors (WH57). This versatility helps you assemble a richer, more nuanced picture of local conditions across multiple locations.

• Broad sensor compatibility for richer weather insight across spaces like home, garden, or shed.
• Live data viewing via the Ecowitt app or WS View Plus, with options to publish to Weather Underground, WOW, Weather Cloud, Ecowitt Weather, or other sites using standard protocols.
• Regional RF frequencies available (915/868/433 MHz) to match your location and ensure reliable wireless reception.
• Firmware upkeeping: automatic updates are optional, preserving your data if you choose to delay updates.

• Easy Wi‑Fi configuration and fast deployment compared to older models.
• Flexible placement thanks to the USB extension and unobtrusive gateway footprint.

Practical use cases

Place the GW1100 near a router in a sunny porch, greenhouse, or study to monitor temperature swings, humidity shifts, and barometric pressure. Compare readings across connected sensors to spot trends and plan activities such as irrigation, ventilation, or outdoor projects with greater confidence.

What the data enables

With live readings and calibration options, you can tailor sensor visibility to your needs and share data with Weather Underground, Weather Cloud, or Ecowitt’s own ecosystem. The gateway supports a proactive, informed approach to weather and environment in daily life, without making guarantees—just more informed possibilities.
