1. Introduction
Thanks for purchasing this WH55 wireless
multi-channel water leak detection sensor. The
alarm will be triggered when water seepage is
detected. The wireless signal can be received
by the GW1000 Wi-Fi Gateway(sold
separately) and the sensor data can be viewed
on our WS View mobile application after the
Wi-Fi configuration done. This device will
also work with the HP2551/HP3500/HP3501
weather station(all sold separately) in the
future.
To ensure the best product performance, please

4
read this manual and retain it for future
reference.

3.1 Features
Detects water seepage every 3 seconds.
Emits loud alarm with 90dB once triggered.
High or low sensor sensitivity selectable to
meet different requirements.
Works with GW1000 Wi-Fi gateway (sold
separately) to complete the wifi
configuration on WS View application.
View live sensor data on the app once wifi
configuration done.
Email alerts available once the gateway
device added successfully on our free
Ecowitt Weather Server:
https://www.ecowitt.net.
Each GW1000 gateway supports to add up

8
to 4 channels water leak sensors. Channel
names can be edited both on the app and
Ecowitt Weather Server.
Battery power level display on the WS View
App
4. Setup Guide
4.1 Install batteries
1.Remove the battery door on the back of the
transmitter(s) by taking off the cover, as shown
in Figure 2 .

2. Before inserting the batteries, find the dip
switches instruction above the battery
compartment and set the sensor sensitivity
level and channel number:
Sensitivity Level: To change the sensor
sensitivity of detection (High or Low), change
Dip Switch 3, as referenced in Figure 3.
High sensitivity: The water leakage alarm will
be triggered when the detected water leak
capacitance value equals to or over 60PF and
be muted when the value equals to or lower
50PF.

11
Low sensitivity: The water leakage alarm will
be triggered when the detected water leak
capacitance value equals to or over 90PF and
be muted when the value equals to or lower
80PF.
Channel Number: This device supports up to
four sensors. To set each channel number,
change Dip Switches 1 and 2 , as referenced in
Figure 3.

12
Switch in down position. Switch in up
position.

3.Insert two 1.5V AAA batteries.
The LED indicator will turn on for four
seconds and normally flash once every 60
seconds (the sensor transmission update
period).
Note: If no LED light up or is lighted
permanently, make sure the battery is inserted
the correct way or a proper reset is happened.
Do not install the batteries backwards. You can
permanently damage the sensor.
4.Verify the correct channel number (CH) and
sensor sensitivity level (High or Low) are

14
selected.
5.Close the battery door.
Repeat for the additional remote
transmitters(sold separately), verifying each
remote is on a different channel.
5. Sensor Placement
This device can be placed at multi locations
include under-the-sink cabinet in a kitchen or
bathroom, near a water heater, a basements, a
sump pump, a toilet, a washer, a humidifier, an
AC unit, or ice-making refrigerator.

6. Wi-Fi Configuration with gateway
If you want to view the water leak sensor data
on your mobile application and receive email
alerts on our weather server, you need to pair
this device with our GW1000 Wi-Fi Gateway
(sold separately).
6.1 Pair with Gateway
If the GW1000 has been in operation, and you
have never had any WH55 multi-channel
water leak sensor(s) setup before, just power
up the sensor(s) and GW1000 will pick the
sensor data automatically.

16
If one WH55 sensor has been hooked on
GW1000 before, and you have a new WH55
sensor to replace the old one, just power off
the old sensor and power on the new sensor,
the gateway will pick up the new sensor data
automatically.
Then you may go to the Sensor ID page of the
app (requires the Wi-Fi configuration done
first) to Re-register or disable sensor(s) to
ensure it’s on the correct channel you.

17
6.2 Wi-Fi Connection for the Gateway
For this part, please refer to the manual of the
GW1000 Wi-Fi gateway.
Any question, please contact the customer
service.
7. View Online Data with WS View
When the Wi-Fi configuration is done, you
may view leakage detection condition as well
as the sensor battery level on WS view App at
the live data page.

19
Note: It requires your phone and the gateway
using the same network to view your sensor
data on the WS View app.
To remote monitor the sensor data, please
upload the data to our free Ecowitt Weather
Server: https://www.ecowitt.net.
Detailed operation instructions can be found
on the GW1000 manual.
Any question, please feel free to contact our
customer service at [e-mail]

8. Set Email Alerts
Once your device added successfully on the
Ecowitt Weather server, you may set alerts for
the water leak sensor(s) on the website to get
email notifications.
