1. Introduction
Thank you for your purchase of the Wireless Wi-Fi Weather Station. The
following user guide provides step by step instructions for installation,
operation and troubleshooting.
2. Warnings and Cautions
Warning: Any metal object may attract a lightning strike, including your
weather station mounting pole. Never install the weather station in a storm.
Warning: Installing your weather station in a high location may result
in injury or death. Perform as much of the initial check and operation on the
ground and inside a building or home. Only install the weather station on a
clear, dry day.
3. Quick Start Guide
Although the manual is comprehensive, much of the information contained
may be intuitive. In addition, the manual does not flow properly because the
sections are organized by components.
The following Quick Start Guide provides only the necessary steps to install,
operate the weather station, and upload to the internet, along with references
to the pertinent sections.

4. Pre-Installation Checkout and Site Survey
4.1 Pre Installation Checkout
Before installing your weather station in the permanent location, we
recommend operating the weather station for one week in a temporary location
with easy access. This will allow you to check out all of the functions, insure
proper operation, and familiarize you with the weather station and calibration
procedures. This will also allow you to test the wireless range of the weather
station.
4.2 Site Survey
Perform a site survey before installing the weather station. Consider the
following:
1. Clean the rain gauge every few months and change the batteries every
2-3 years. Provide easy access to the weather station.
2. Avoid radiant heat transfer from buildings and structures. Install the
sensor array at least 2 meter from any building, structure, ground, or
roof top.
3. Avoid wind and rain obstructions. The rule of thumb is to install the
sensor array at least four times the distance of the height of the tallest
obstruction. For example, if the building is 20’ tall, and the mounting
pole is 6’ tall, install 4 x (20 – 6)’ = 56’ away.
4. Wireless Range. The radio communication between receiver and
transmitter in an open field can reach a distance of up to 100 meters,
providing there are no interfering obstacles such as buildings, trees,
vehicles, high voltage lines. Wireless signals will not penetrate metal
buildings. Under most conditions, the maximum wireless range is
30m.
5. Radio interference such as PCs, radios or TV sets can, in the worst
case, entirely cut off radio communication. Please take this into
consideration when choosing console or mounting locations. Make
sure your display console is at least five feet away from any electronic
device to avoid interference.

Table 3: Sensor assembly detailed items
5.2.1 Install U-bolts and mounting pole
Installation of the U-bolts, which are in turn used to mount the sensor package
on a pole, requires installation of an included metal plate to receive the U-bolt
ends. The metal plate, visible in Figure 2, has four holes through which the
ends of the two U-Bolts will fit. The plate itself is inserted in a groove on the
bottom of the unit. Note that one side of the plate has a straight edge (which
goes into the groove), the other side is bent at a 90-degree angle and has a
curved profile (which will end up “hugging” the mounting pole). Once the
metal plate is inserted, remove nuts from the U-Bolts and insert both U-bolts
through the respective holes of the metal plate as shown in Figure 2.
Figure 2: U-Bolt installation
Loosely screw on the nuts on the ends of the U-bolts. You will tighten these
later during final mounting. Final assembly is shown in Figure 3.
Figure 3: U-Bolts and nuts installed
The plate and U-Bolts are not yet needed at this stage but doing this now may

7
help avoid damaging wind vane and wind speed cups later on.
5.2.2 Install wind vane
Push the wind vane onto the shaft on the bottom of the sensor, until it stops
moving further, as shown in figure 4.
Tighten the set screw, with a Philips screw driver (size PH0), until the wind
vane cannot be removed from the axle, as shown in figure 4. Make sure the
wind vane spin freely. The wind vane’s movement has a small amount of
friction, which is helpful in providing steady wind direction measurements.
Figure 4: Wind vane installation diagram
5.2.3 Install wind speed
Push the wind speed cups into the shaft as shown in figure 5.
Tighten the set screw with screw driver. Make sure the wind speed cups can
spin freely.
Figure 5: Wind speed cup installation diagram
5.2.4 Install Rain Gauge
Install the rain gauge funnel. Rotate clockwise to attach the funnel to the

8
outdoor sensor.
Figure 6: Rain gauge installation and maintenance
5.2.5 Install Batteries
Insert 2XAA batteries in the battery compartment. The LED indicator on the
back of the transmitter will turn on for four seconds and normally flash once
every 16 seconds (the sensor transmission update period).
Figure 7: Battery installation diagram

9
Note: If no LED light up or is permanently on, make sure the batteries are
inserted the correct way or a proper reset has happened. Do not install the
batteries backwards. You can permanently damage the outdoor sensor.
Note: We recommend 1.5V lithium batteries for cold weather climates, but
alkaline batteries are enough for most climates. We do not recommend
rechargeable batteries. They have lower voltages, they do not operate well at
wide temperature ranges, and do not last as long, resulting in poorer reception.
5.2.6 Mount assembled outdoor sensor package
5.2.6.1 Before you mount
Before proceeding with the outdoor mounting detailed in this section, you may
want to skip to setup instructions in section 6 and onwards first, while you
keep the assembled outdoor sensor package nearby (although preferably not
closer than 5 ft. from the console). This will make any troubleshooting and
adjustments easier and avoids any distance or interference related issues from
the setup.
After setup is complete and everything is working, return here for outdoor
mounting. If issues show up after outdoor mounting they are almost certainly
related to distance, obstacles etc.
5.2.6.2 Mounting
You can attach a pipe to a permanent structure and then attach the sensor
package to it (see Figure 8). The U-Bolts will accommodate a pipe diameter of
1-2 inches (pipe not included).
Figure 8: Sensor package mounting diagram
Finally, place the sensor package on top of the prepared mounting pipe.The U-
Bolts should be loose enough to allow this but loosen the nuts as necessary.
Once placed, hand tightens all four nuts, taking care to do so evenly.
Now you will need to align the whole package in the proper direction by
Figure 9

10
rotating it on top of the mounting pipe as needed. Locate the arrow
labeled “WEST” that you will find on top of the sensor package right next
to the antena. You must rotate the whole sensor package until this arrow
points due West. To achieve proper alignment, it is helpful to use
a compass (many cell phones have a compass application).
Once rotated in the correct orientation, lightly tighten the bolts a little more
(use a wrench) to prevent further rotation.
Note: Use the bubble level next to the rain sensor to make sure the sensor
array is completely level. If the sensor is not level then the rain gauge will
measure inaccurately.
5.2.7 Reset Button and Transmitter LED
In the event that the sensor array is not transmitting, reset the sensor array.
With an open ended paperclip, press and hold the RESET BUTTON for three
seconds and resynchronize with console by powering down and up the console.
Please put the console with the sensor array about 3 meters away.
Figure 9: Reset button and Transmitter LED location
5.3 Optional sensors
Important: When more sensors, excluding the original sensor array, to be
paired with the display, DC power supply must be applied as console will turn
on its RF receiver permanently, this increases the current consumption
significantly.
Optional sensor data can be viewed by WS View Plus APP on its live data
page. Console LCD is reserved for integrated sensor array data hosting only!!
The following optional sensors (sold separately) can be used with console
display.

11
If you have purchased extra sensors, just simply power them up, the display
console will receive the data automatically and send the data directly to
Ecowitt.net (requires to set the console uploading to ecowitt.net first). The
data will not display on the console (pass through only) and sensor
management and calibration can only be realized via WS View PlusAPP.
Note: When optional sensor (s) added, it requires that the console must be
powered by USB connection.

5.5 Best Practices for Wireless Communication
Note: To insure proper communication, mount the remote sensor(s)
upright on a vertical surface, such as a wall. Do not lay the sensorflat.
Wireless communication is susceptible to interference, distance, walls and
metal barriers. We recommend the following best practices for trouble free
wireless communication.
Electro-Magnetic Interference (EMI). Keep the console several feet away
from computer monitors and TVs.

15
Radio Frequency Interference (RFI). If you have other devices operating on
the same frequency band as your indoor and/or outdoor sensors and
experience intermittent communication between sensor and console, try
turning off these other devices for troubleshooting purposes. You may need to
relocate the transmitters or receivers to avoid the interference and establish
reliable communication. The frequencies used by the sensors are one of
(depending on your location): 433, 868, or 915 MHz (915 MHz for United
States).
1. Line of Sight Rating. This device is rated at 300 feet line of sight (no
interference, barriers or walls) but typically you will get 100 feet
maximum under most real-world installations, which include passing
through barriers or walls.
2. Metal Barriers. Radio frequency will not pass through metal barriers
such as aluminum siding. If you have metal siding, align the remote
and console through a window to get a clear line of sight.
The following is a table of reception loss vs. the transmission medium.
Each “wall” or obstruction decreases the transmission range by the factor
shown below.

Figure 13: Display console front and back
Power on the console as show on Figure 14.
(1) Insert the 5VAC adaptor into the back of the display console
Note: Place the outdoor sensor array about 5 to 10 feet from the display
console and wait several minutes for the remote sensors to synchronize
with the display console.
(2) Insert 2 x AA good qualityAlkaline or Lithium batteries per Figure 14.
(3) Wait several minutes for the remote sensors to synchronize with the
display console.
(4) In order to prevent the display console's own temperature rising from
affecting the accurate reading of temperature and humidity, the
temperature and humidity sensor is placed at the antenna end, away from
the station body. Orient the console antenna straight up for accurate
indoor temperature and humidity reading.
