Table 1: Package content
If any component is missing from the package, or
broken, please contact our Customer Service
department to resolve the issue.
Note: The gateway must be plugged into a USB
(2.0 or later) port for its power supply. The USB
extension cable (USB type A - Male straight to

4
female straight; included) should be used so that
the gateway is sitting further from AC adapters
which is a heat source as well as EMI
interference source. The using of this USB
extension cable will make the gateway performs
better in terms of radio signal reception, and
measures indoor temperature, humidity more
accurate.

intervals
Note: All the optional sensors supported can be
found on our website: www.ecowitt.com.
Make sure to select the model of the units
with the same RF frequency as your
gateway (the frequency is different for
various countries because of regulations).
Note: www.ecowitt.net hosts all the sensor
supported, however, it is not necessary
true to other data hosting services. For
example, the Wunderground only accepts
outdoor sensor data, therefore it will not
display the following sensor data on their
website:
•Indoor temperature and humidity (from the
GW1100 built-in 3-in-1 sensor)

10
•Multi-channel temperature and humidity
(from the WH31 sensor) or Multi-channel
temp (from WN30 sensor)
•Soil moisture (from the WH51 sensor)
•PM2.5 data (from the WH41/43 sensor).
•Lightning data (from the WH57 sensor)
•Water leakage condition (from the WH55
Sensor)
•Water/Soil temp (from WN34 sensor)
•PM2.5/PM10/CO2/temperature and humidity
data (from the WH45 Sensor)
•Leaf wetness sensor(from WN35 sensor)
To view and record all the sensors data remotely,
we recommend you to use the Ecowitt server.

3.1.1 LED Indicators
RF (Blue): Indicates the status of RF
communication with the station.
Flash (each): Indicates one packet of RF data
from a sensor was received.
Off (steady): Indicates none RF data received.
Wi-Fi (Red): Indicates the status of the Wi-Fi
connection.
Off : Wi-Fi connection to router failed;
On: GW1100 was provisioned to router and
has data sent to any one of the cloud data
hosting successfully.
Flash slowly: GW1100 connected to WiFi
router, but failed to publish data to any of the
weather service on cloud.
Flash rapidly: GW1100 was in factory reset
default state. It has never been configured for
router and weather server.
