Product Overview
Thank you for purchasing the EOSS EWS1 Wireless Weather
Station. Please ensure that you have read the product manual
and instructions in full, prior to installation and use. Failure to
do so may result in product failure/damage or incorrect
operation and therefore impact the product performance.
The EWS1 Wireless Weather Station is an indoor/outdoor
device that uses a wireless sensor to monitor parameters such
as temperature, barometric pressure and humidity. The
weather station displays both the current weather data and
weather forecast.

Getting Started
1. Insert batteries into the weather station monitor.
(3 x 1.5 V AAA not included)
2. Insert batteries into the wireless sensor.
(2 x 1.5 V AAA not included)
3. When inserting the batteries make sure the polarity is
correct to avoid damaging the weather station or sensor.
Only use alkaline batteries of the same type; do not use
rechargeable batteries.
4. Place the two units next to each other. The weather
station will automatically detect the sensor signal within 3
minutes. If signal from the sensor is not detected,
long-press the button on the weather station to repeat
the search. Refer to page.8 for more info.
5. We recommend placing the sensor on the north side of
the house. The range of the sensor may decrease
substantially in areas with a large number of obstacles.
6. The sensor is resistant to water mist; however, it should
not be exposed to sustained rain.
7. Do not place the sensor onto metal objects as this will
reduce its transmission range.
8. If the low battery icon is displayed, replace batteries in the
sensor or weather station.
All changes in values are made using buttons and .
After setting the desired value and not pressing any other
buttons, the set values will automatically save and the
display will switch to the main screen.

1. Press and hold the channel button until you hear a
beep sound. The signal reception symbol will appear
and start pulsing, searching to pair with the wireless sensor.
2. Unscrew the cover of the battery compartment on the rear
of the wireless sensor and set the sensor switch to the
desired sensor channel number (1, 2, 3), then insert
batteries (2×1.5 V AAA).
3. The monitor should automatically display the wireless
sensor data after a short while.
4. If it does not pair with the wireless sensor then you can
press the pairing button on the back of the sensor to
automatically pair.
5. Once pairing is successful long-press the button to
exit searching mode and the button will stop pulsing.
Press the button repeatedly to display data from all
connected wireless sensors on the weather station, one
by one. You can also activate cycling through data from
all connected wireless sensors:
1. Turning on cycling
Repeatedly press the button until the display shows
the icon. Data from all 3 wireless sensors will be
shown automatically and repeatedly one after another.
2. Turning off cycling
Repeatedly press the button until the icon
disappears.

The station shows atmospheric pressure in hPa or in Hg
and keeps a history of pressure readings for the last 12
hours. To achieve a more accurate calculation of pressure
values, it is advised to manually set the altitude for the
place where the weather station is being used.
Setting Altitude and Atmospheric Pressure
Temperature limits can be set independently for up to 3
outdoor temperature wireless sensors. When minimum or
maximum temperature limit is activated, the (min)
or (max) icon will appear on the screen and
disappear after deactivation.
Setting Temperature Limits for Max/Min Temps
1. Short-press the button three times
2. Press the button for 3 seconds and use the arrows to
set altitude between -90 m to +1,990 m (10m increments).
3. Pressing the button switches between M/hpa and
Ft/in Hg units.
4. Short-press the button to quit settings.

While on the main screen, repeatedly press the
button to switch to sensor 1, 2 or 3 and proceed for each
sensor as follows.
1. Short press the button four times.
2. Press the button for 3 seconds and set the minimum
outdoor temperature.
3. Short press the button and activate (ON)/deactivate
(OFF) the outdoor minimum temperature alert.
4. Short press the button and set the maximum outdoor
temperature.
5. Short press the button and activate (ON)/deactivate
(OFF) the outdoor maximum temperature alert.
6. Short press the button and set the minimum indoor
temperature.
7. Short press the button and activate (ON)/deactivate
(OFF) the indoor minimum temperature alert.
8. Short press the button and set the maximum indoor
temperature.
9. Short press the button and activate (ON)/deactivate
(OFF) the indoor maximum temperature alert. When the
set temperature limit is exceeded, an audio alarm will
sound for 1 minute and the value will begin flashing.
Pressing any button on the screen cancels the alert
sound, but the symbol of an active alert will continue
flashing. Once temperature drops below the set limit, the
symbol on the screen will stop flashing.

When powered only by 3× 1.5 V AAA batteries:
Display backlighting is off. Pressing the Snooze/Light
button will turn the display backlight on for 5
seconds, then it turns off again. When the station is only
powered by batteries, permanent backlighting of the
display cannot be activated!

measured/set data.
If batteries are not inserted and you unplug the USB
cable, all data will be erased.
When powered via USB to DC jack cable:
Permanent backlighting is set automatically.
Repeatedly pressing the Snooze/Light button will
allow you to set 4 different levels of permanent

The station forecasts weather on the basis of changes in
atmospheric pressure for the next 12–24 hours for an
area within the range of 15–20 km. The accuracy of
weather forecast is 70–75 %. The forecast icon is
displayed in field no. 7.
As the weather forecast may not always be 100 %
accurate, neither the manufacturer nor the seller can be
held responsible for any loss caused by an incorrect
forecast.
After first setting or after resetting the weather station, a
learning mode will be activated, indicated by
LEARNING… appearing on the screen
The station will evaluate measured data and continuously
increase the accuracy of forecast.
This mode continues for 14 days, then the LEARNING…
icon automatically disappears.
