The Ecowitt GW3000 is an advanced weather-station gateway for users who want a flexible sensor system with Wi-Fi, wired Ethernet, and local data storage. The gateway itself measures indoor temperature, humidity, and barometric pressure, while outdoor weather data comes from compatible Ecowitt sensors purchased separately. Compared with the GW2000, the GW3000 adds greater sensor capacity and microSD logging, making it better suited to larger Home Assistant, garden, irrigation, and environmental-monitoring setups.
Specifications and compatibility notes are based on manufacturer documentation — not independent Atmosiva testing.
Known limitations
- •This is a gateway-only product (model GW3000CA / GW3000). Outdoor weather sensors are sold separately — it does not include a WS90 or other outdoor array
- •Package typically includes the GW3000 gateway, antenna, USB-C power cable, and manuals. A microSD card is not included. An Ethernet cable and 5V USB power adapter may be separate purchases — confirm the current Amazon listing before buying
- •915 MHz is the common US-region RF version on Amazon.com; regional frequencies differ and must match your Ecowitt sensors
- •Supports a large Ecowitt sensor ecosystem, with channel limits that vary by sensor family — check Ecowitt compatibility charts for your planned mix
- •microSD local logging requires a compatible card (FAT32 per Ecowitt docs) and configuration; verify firmware support for newer accessories
Expansion options
- •Outdoor arrays such as WS90, WS80, WS85, WS69, or WS68 (sold separately)
- •WH40 traditional rain gauge and other rainfall options when preferred
- •WH51 / WH51L soil moisture probes for garden and irrigation setups
- •WH57 lightning detection and WH41 / WH43 air-quality sensors
- •Additional Ecowitt RF and IoT accessories on supported firmware — channel limits vary by sensor family
Pros
- + Wired Ethernet and Wi-Fi
- + microSD local logging
- + Built-in indoor temp/humidity/pressure sensing
- + Broad Ecowitt sensor support
- + Good fit for Home Assistant and local-data users
- + More expansion capacity than GW2000
Cons
- − Outdoor sensors sold separately
- − microSD card usually separate
- − Ethernet cable may be separate
- − More complex than buying a complete bundle such as GW2001
- − Sensor-family limits can require planning
Technical Specifications
Not included — outdoor wind requires a compatible Ecowitt array (e.g. WS90)
Not included — outdoor rainfall requires a compatible Ecowitt sensor (e.g. WS90 or WH40)
Built-in indoor temp/humidity/pressure probe on the gateway (per Ecowitt GW3000 specs)
2.4 GHz Wi-Fi and RJ45 Ethernet; 915 MHz RF reception on typical US Amazon listings (match regional SKU). Local TCP/HTTP endpoints and microSD logging documented by Ecowitt; custom weather-server uploads supported
RF reception to Ecowitt sensors — regional 915/868/433 MHz SKUs must match your sensors
Home Assistant Ecowitt integration (built-in local push and official HACS HTTP API), Ecowitt.net, Weather Underground, WeatherCloud, WOW, and custom HTTP/TCP endpoints per Ecowitt Web UI documentation
USB-C 5V power (USB-C cable included per Ecowitt/Amazon listings; 5V adapter often sold separately)
Indoor probe update about 1 minute (per Ecowitt documentation); outdoor sensors follow their own RF intervals
