Our take on the GW1100 Wi-Fi Gateway with Built-in Temperature/Humidity/Barometric

The Ecowitt GW1100 is a small Wi-Fi gateway that receives readings from Ecowitt wireless sensors and publishes them online. It has built-in indoor temperature, humidity and barometric pressure sensors, so it works as a basic weather station on its own once you add outdoor sensors. Setup runs through a browser page, and live data appears in the WS View app or a web page. It uploads to Ecowitt Weather, Weather Underground, Weathercloud, WOW and a custom server. It is the cheaper, simpler sibling of the GW1200: same functions except no IoT device control. Buyers rate it highly for easy setup and reliable data upload, though it needs separate sensors for outdoor readings and the app is basic.

About the GW1100 Wi-Fi Gateway with Built-in Temperature/Humidity/Barometric

The GW1100 is a wireless Wi-Fi weather station gateway with built-in indoor temperature, humidity and barometric pressure sensors. It receives data from Ecowitt transmitter sensors, which are sold separately, so you can build a small home weather station. It does not support connecting IoT devices.

Setup is done in a browser. Power on the gateway, connect your phone or computer to its access point (GW1100X-XXXXXXXX), and open 192.168.4.1. No password is needed unless you set one. Enter your router's SSID and password, then choose your weather services. After Wi-Fi is set up, you can view live data on a web page or in the WS View app.

You can set the time zone and date, manage other sensors, and check each sensor's signal and power status. With a free Ecowitt Weather account, you can view history data as graphs or data spreadsheets. Ecowitt.net is enabled by default. Add the gateway's MAC address to your account to use it. IDs and passkeys for other weather services must be obtained from those services beforehand.
