ECOWITT GW3000 Weather Station Gateway — Wi‑Fi & Ethernet 915 MHz with Built‑in Temp/Humidity/Barometer and SD Port

The ECOWITT GW3000 is a compact Wi‑Fi and Ethernet gateway with integrated temperature, humidity, and barometric sensors plus an SD card port for local data storage.

Designed to be the central hub of an ECOWITT sensor network, the GW3000 accepts 915 MHz wireless inputs from a wide range of outdoor and indoor sensors while providing stable connectivity options through Wi‑Fi or a wired Ethernet connection. Its built‑in three‑in‑one environmental sensor lets you immediately monitor indoor conditions, and the SD slot captures continuous data for backup and transfer. The unit ships with a 0.9 m Type‑C USB power extension for quick setup and flexible placement.

How do I connect the GW3000 to my network?

You can attach the GW3000 to your home network either over Wi‑Fi or using an Ethernet cable; the gateway supports both methods to prevent dropouts in wireless‑challenged locations. Setup is guided via the web interface or the ECOWITT mobile app, and the included manual walks through the steps. For Ethernet access you’ll need to provide your own network cable.

• Choose Wi‑Fi or wired Ethernet during setup
• Configure via the local web page or ECOWITT app
• Ethernet provides consistent uptime in weak Wi‑Fi zones
• Step‑by‑step instructions included in the manual

Which sensors can the GW3000 pair with and how many?

The gateway receives 915 MHz transmissions from many ECOWITT sensors, enabling large, mixed arrays of weather and leak detectors. It supports multiple sensor families at once, so you can combine outdoor weather modules, multi‑channel units, and specialized detectors to expand coverage around your property. Exact supported counts vary by sensor model class.

• Compatible with ECOWITT outdoor and indoor sensors (sold separately)
• Supports multiple multi‑channel and single‑channel sensors simultaneously
• Can integrate water leak detectors and other specialty sensors
• Acts as the network bridge for the ECOWITT ecosystem

What data storage and transfer options does the GW3000 offer?

The GW3000 includes an SD card slot so you can record raw sensor logs locally for redundancy or offline review. Recordings on the SD card are easy to move to a computer for deeper analysis, and local storage reduces reliance solely on cloud services. This is helpful for users who want uninterrupted recording even during internet outages.

• Insert an SD card to log sensor data continuously
• Local files can be copied to a PC for custom analysis
• Useful backup when network connection is unreliable
• Supports export of recorded environmental data

How accurate and useful are the built‑in sensors for indoor monitoring?

The GW3000’s integrated sensor measures room temperature, relative humidity, and atmospheric pressure, giving you instant indoor condition readings from the gateway itself. While not a precision laboratory instrument, the triad of measurements is perfectly suited for home comfort monitoring, HVAC checks, and correlating indoor conditions with outdoor sensor data. Use the gateway’s readings alongside external ECOWITT sensors for a fuller environmental picture.

• Built‑in 3‑in‑1 sensor reports temp, humidity, and barometric pressure
• Good for home comfort checks and baseline indoor readings
• Combine with external sensors for complete property monitoring
• Data available locally and through the network for review

Who is this for? The ECOWITT GW3000 is aimed at homeowners, hobby meteorologists, and small business operators who want a reliable gateway to aggregate multiple wireless weather and leak sensors into one dashboard. It’s a strong choice when you need redundant data storage, the option of wired LAN for stability, and a simple way to expand into a multi‑sensor ECOWITT system without complex networking.
