1 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.
If you are mounting the weather station to a house or structure,
consult a licensed electrician for proper grounding. A direct
lightning strike to a metal pole can damage or destroy your home.
Installing your weather station in a high location may result in
injury or death. Perform as much of the initial check out and
operation on the ground and inside a building or home. Only install
the weather station on a clear, dry, day.
2 Unpacking

If components are missing from the package, or broken, please contact
customer service to resolve the issue.
Note: Batteries for the outdoor sensor package are not included. You will
need 2 AA size batteries, alkaline or Lithium batteries (Lithium
recommended for colder climates).
Note: The console operates using an AC adapter. The included adapter is
a switching-type adapter and can generate a small amount of
electrical interference with the RF reception in the console, when
placed too close to the console. Please keep the console display at
least 2 ft. or 0.5 m away from the power adapter to ensure best RF
reception from the outdoor sensor package.
Note: The console can store historical data on a memory card. This
memory card is not included. If you want to use one you will need
a microSD memory card. The supported max capacity of the card is
32G (Format: FAT32). A 1GB card will store more than 10 years’
worth of data, so you do not need a very large capacity card. There
is also no requirement on the speed class of this card as data writing
happens infrequently and is not speed critical.

4 Set up Guide
4.1 Pre Installation Checkout
To complete assembly you will need a Philips screwdriver (size PH0) and a
wrench (size M6; included in package).
Note: We suggest you assemble all components of the weather station,
including console in one location so you can easily test functionality.
After testing, place the outdoor sensor package in the desired
location. Note, however, that movement during assembly, and
movement after assembly can cause the rain sensor to “falsely”
register rain. It is therefore best if you do not connect the console to
any Internet services until you have reset these false readings using
the console. The errant values may be hard to remove from Internet
services if you do not reset first.
Attention:
Follow suggested order for battery installation (outdoor sensor first,
console second)
Ensure batteries are installed with correct polarity (+/-)
Do not mix old and new batteries
Do not use rechargeable batteries
If outdoor temperature may go below 32F or 0C for prolonged periods,
Lithium based batteries are suggested over alkaline type batteries for the
outdoor sensor array
12
4.2 Site Survey
Perform a site survey before installing the weather station. Consider the
following:
1. You must 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. In general,
install the sensor array at least 5’ or 1.52m 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’ or 6.10m tall
and the mounting pole is 6’ or 1.83m tall, install the sensor array 4 x
(20 – 6)’ = 56’ or 4 x (6.1-1.83)=17.08m away.
4. Mount the sensor array in direct sunlight for accurate temperature
readings.
5. Installing the weather station over sprinkler systems or other
unnatural vegetation may affect temperature and humidity readings.
We suggest mounting the sensor array over natural vegetation.
6. Wireless Range. Radio communication between receiver and
transmitter in an open field can reach a distance of up to 330 feet or
100 meter, providing there are no interfering obstacles such as
buildings, trees, vehicles and high voltage lines. Wireless signals
will not penetrate metal buildings. Under most conditions, the
maximum wireless range is 100’ or 30m.
7. Radio Interference. Computers, radios, televisions and other sources
can interfere with radio communications between the sensor array
and console. Please take this into consideration when choosing
console or mounting locations. Make sure your display console is at
least five feet or 1.52 meter away from any electronic device to
avoid interference.

Table: Sensor assembly detailed items
4.3.1 Install U-bolts and metal plate
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 6 on the right side, 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 (opposite side of solar
panel). 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 6 .
14
Figure 6: 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 7 .
Figure 7: U-Bolts and nuts installed
The plate and U-Bolts are not yet needed at this stage but doing this now
may help avoid damaging wind vane and wind speed cups later on.
Handling of the sensor package with wind vane and speed cups installed to
install these bolts is more difficult and more likely to lead to damage.
4.3.2 Install wind vane
Push the wind vane onto the shaft on the bottom side of the sensor package,
until it goes no further, as shown on the left side in Figure 8 . Next, tighten
the set screw, with a Philips screwdriver (size PH0), as shown on the right
side, until the wind vane cannot be removed from the axle. Make sure the
wind vane can rotate freely. The wind vane’s movement has a small amount
of friction, which is helpful in providing steady wind direction
measurements.
15
Figure 8: Wind vane installation diagram
4.3.3 Install wind speed cups
Push the wind speed cup assembly onto the shaft on the opposite side of the
wind vane, as shown in Figure 9 on the left side. Tighten the set screw, with
a Philips screwdriver (size PH0), as shown on the right side. Make sure the
cup assembly can rotate freely. There should be no noticeable friction when
it is turning.
Figure 9: Wind speed cup installation diagram
4.3.4 Install Batteries in sensor package
Open the battery compartment with a screwdriver and insert 2 AA batteries
in the battery compartment. The LED indicator on the back of the sensor
package (item 9) will turn on for four seconds and then flash once every 16
seconds indicating sensor data transmission. If you did not pay attention,
you may have missed the initial indication. You can always remove the
batteries and start over, but if you see the flash once every 16 seconds,
everything should be OK.
16
Figure 10: Battery installation diagram
Note: If LED does not light up or is on permanently, make sure the battery
is inserted the correct way and inserted fully, starting over if
necessary. Do not install the batteries backwards as it may
permanently damage the outdoor sensor.
Note: We recommend Lithium batteries for cold weather climates, but
alkaline batteries are sufficient for most climates. Rechargeable
batteries have lower voltages and should never be used.
4.3.5 Mount assembled outdoor sensor package
4.3.5.1 Before you mount
Before proceeding with the outdoor mounting detailed in this section, you
may want to skip to setup instructions in section 5.7 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.
4.3.5.2 Mounting
You can attach a pipe to a permanent structure and then attach the sensor
package to it (see Figure 11). The U-Bolts will accommodate a pipe diameter of
1-2 inches (pipe not included).
17
Figure 11: Sensor package mounting diagram
Make sure the mounting pipe is vertical, or very close to it. Use a level if
needed.
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. Do not use a wrench yet!
Now you will need to align the whole package in the proper direction by
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
light sensor, on the opposite side of the solar panel. 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: The orientation to WEST is necessary for two reasons. The most
important one is to position the solar panel and light sensor in the
most advantageous position for recording solar radiation and
charging internal capacitors. Secondly it causes a zero reading for
wind direction to correspond to due NORTH, as is customary. This
orientation is correct for installations in the northern hemisphere. If
you are installing in the southern hemisphere, the correct orientation
to achieve the same optimal positioning is to have the “WEST”
18
arrow actually point due EAST! This has the side effect, however,
of lining up the 0 reading of the wind direction with SOUTH. This
needs to be corrected using a 180-degree offset in the calibration
settings (see section 5.12 Calibration Mode).
Now look at the bubble level. The bubble should be fully inside the red
circle. If it is not, wind direction, speed, and rain readings may not operate
correctly or accurately. Adjust the mounting pipe as necessary. If the bubble
is close, but not quite inside the circle, and you cannot adjust the mounting
pipe, you may have to experiment with small wooden or heavy cardboard
shims between the sensor package and the top of the mounting pole to
achieve the desired result (this will require loosening the bolts and some
experimentation).
Make sure you check, and correct if necessary, the westerly orientation as
the final installation step, and now tighten the bolts with a wrench. Do not
over tighten, but make sure strong wind and/or rain cannot move the sensor
package.
Note: If you tested the full assembly indoors and then came back here for
instructions and mounted to sensor package outdoor you may want
to make some further adjustments on the console. The
transportation from indoor to outdoor and handling of the sensor is
likely to have “tripped” the rainfall sensing bucket one or more
times and consequently the console may have registered rainfall that
did not really exist. You can use console functions to clear this from
history. Doing so is also important to avoid false registration of
these readings with weather services.
4.3.6 Reset Button and Transmitter LED
In the event the sensor array is not transmitting, reset the sensor array.
Using a bent-open paperclip, press and hold the RESET BUTTON (see
Figure 12) to affect a reset: the LED turns on while the RESET button is
depressed, and you can now let go. The LED should then resume as normal,
flashing approximately once every 16 seconds.
19
Figure 12: Reset button and Transmitter LED location
4.4 Indoor Sensor Set Up
Note: To avoid permanent damage, please take note of the battery polarity
before inserting the batteries. Looking at Figure 13 from left to right
the left-most (or bottom) battery is to be installed with its + terminal
pointing down, and the other battery with its + terminal pointing up.
Remove the battery door on the back of the sensor by sliding it in the
direction of the arrow. Insert two AA batteries as described and put
compartment door back and slide it in the opposite direction to lock.
Switch to select temperature display in Celsius or Fahrenheit.

9. Close the battery door.
Repeat for the additional remote transmitters, verifying each remote is on a
different channel.
22
4.5.2 Sensor Placement
The best mounting location for the indoor sensor is in a location that never
receives direct sunlight, not even through windows. Also, do not install in a
location where a nearby radiant heat source (radiator, heaters, etc.) will
affect it. Direct sunlight and radiant heat sources will result in inaccurate
temperature readings.
The sensor is meant to provide indoor conditions for display on the console,
but if you would rather have a second source for outdoor conditions instead,
you can mount this unit outside. The unit is weatherproof, but besides
heeding the placement instructions above, you should also attempt to mount
the unit under cover (eve or awning or similar).
To mount or hang the unit on a wall or wood beam:
Use a screw or nail to affix the remote sensor to the wall, as shown on
the left side of Figure 17, or
Hang the remote sensor using a string, as shown in right side of Figure
17
Figure 17: Indoor sensor mounting
Note: Make sure the sensor is mounted vertically and not lying down on a
flat surface. This will insure optimum reception. Wireless signals
are impacted by distance, interference (other weather stations,
wireless phones, wireless routers, TVs and computer monitors), and
23
transmission barriers, such as walls. In general, wireless signals will
not penetrate solid metal and earth (down a hill, for example).
4.6 Best Practices for Wireless Communication
Wireless (RF) communication is susceptible to interference, distance, walls
and metal barriers. We recommend the following best practices for trouble
free wireless communication between both sensor packages and the console:
Indoor sensor placement: The sensor will have the longest reach for
its signal when mounted or hung vertically. Avoid laying it down on a
flat surface.
Electro-Magnetic Interference (EMI). Keep the console several feet
away from computer monitors and TVs.
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
package 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, 868 MHz
for European, 433 MHz for other area).
Line of Sight Rating. This device is rated at 300 feet line of sight
(under ideal circumstances; no interference, barriers or walls), but in
most real-world scenarios, including a wall or two, you will be able to
go about 100 feet.
Metal Barriers. Radio frequency will not pass through metal barriers
such as aluminum siding or metal wall framing. If you have such metal
barriers and experience communication problems, you must change the
placement of sensor package and or console.
The following table shows different transmission media and expected signal
strength reductions. Each “wall” or obstruction decreases the transmission
range by the factor shown below.

Table: Supported weather services
Note: If you are testing the setup with the outdoor sensor package nearby
and indoor, you may want to consider connecting to Wi-Fi, but not yet
configuring any of the weather services. The reason is that while indoor the
temperatures and humidity recorded by the outdoor sensor, and as reported
47
to the weather service(s) will reflect indoor conditions, and not outdoor
conditions. Therefore, they will be incorrect. Furthermore, the rainfall
bucket may be tripped during handling, causing rain to register while it may
not actually have been raining. One way to prevent this is to follow all
instructions, except to use an incorrect password, on purpose! Then, after
final outdoor installation, come back and change the password after clearing
console history. That will start uploading to the services with a clean slate.
Press or key to enter Weather Server set up mode. The device
can be configured to send real-time data to wunderground.com®. Enter the

(1) Temperature errors can occur when a sensor is placed too close to a
heat source (such as a building structure, the ground or trees).
(2)
69
(3) To calibrate temperature, we recommend a mercury or red spirit
(fluid) thermometer. Bi-metal (dial) and digital thermometers (from
other weather stations) are not a good source and have their own
margin of error. Using a local weather station in your area is also a
poor source due to changes in location, timing (airport weather
stations are only updated once per hour) and possible calibration
errors (many official weather stations are not properly installed and
calibrated).
(4)
(5) Place the sensor in a shaded, controlled environment next to the
fluid thermometer, and allow the sensor to stabilize for 3 hours.
Compare this temperature to the fluid thermometer and adjust the
console to match the fluid thermometer.
(6)
(7) Humidity is a difficult parameter to measure electronically and
drifts over time due to contamination. In addition, location has an
adverse affect on humidity readings (installation over dirt vs. lawn
for example).
(8)
(9) Official stations recalibrate or replace humidity sensors on a yearly
basis. Due to manufacturing tolerances, the humidity is accurate
to ± 5%. To improve this accuracy, the indoor and outdoor humidity
can be calibrated using an accurate source, such as a sling
psychrometer.
(10)
(11) The display console displays two different pressures: absolute
(measured) and relative (corrected to sea-level).
To compare pressure conditions from one location to another,
meteorologists correct pressure to sea-level conditions. Because the
air pressure decreases as you rise in altitude, the sea-level corrected
pressure (the pressure your location would be at if located at
sea-level) is generally higher than your measured pressure.
70
Thus, your absolute pressure may read 28.62 inHg (969 mb) at an
altitude of 1000 feet (305 m), but the relative pressure is 30.00 inHg
(1016 mb).
The standard sea-level pressure is 29.92 in Hg (1013 mb). This is
the average sea-level pressure around the world. Relative pressure
measurements greater than 29.92 inHg (1013 mb) are considered
high pressure and relative pressure measurements less than 29.92
inHg are considered low pressure.
To determine the relative pressure for your location, locate an
official reporting station near you (the internet is the best source for
real time barometer conditions, such as Weather.com or
Wunderground.com), and set your weather station to match the
official reporting station.
(12) Only use this if you improperly installed the weather station sensor
array, and did not point the direction reference to true north.
(13)
(14) The default conversion factor based on the wavelength for bright
sunlight is 126.7 lux / w/m
2
. This variable can be adjusted by
photovoltaic experts based on the light wavelength of interest, but
for most weather station owners, is accurate for typical applications,
such as calculating evapotransporation and solar panel efficiency.
(15)
(16) Wind speed is the most sensitive to installation constraints. The
rule of thumb for properly installing a wind speed sensor is 4 x the
distance of the tallest obstruction. For example, if your house is 20’
tall and you mount the sensor on a 5’ pole:
Distance = 4 x (20 – 5)’ = 60’ or =4 x (6.10-1.52)=18.32m.
Many installations are not perfect and installing the weather station
on a roof can be difficult. Thus, you can calibrate for this error with
a wind speed multiplier.
71
In addition to the installation challenges, wind cup bearings
(moving parts) wear over time.
Without a calibrated source, wind speed can be difficult to measure.
We recommend using a calibrated wind meter (not included) and a
constant speed, high speed fan.
Note: If located in southern hemisphere, please follow the steps to
calibrate the wind direction:
1. Install the outdoor sensor package with the West arrow on the
sensor pointing due East.
2. Check the wind direction offset (Default: equals to the current
wind direction )
If:
Current wind direction offset < 180, then it should be calibrated to
be: current wind direction + 180
If:
Current wind direction offset > 180, then it should be calibrated to
be: current wind direction - 180
For example, if the current wind direction is 288, then you’ll need to
set the wind direction offset to be: 288-180=108.
If the current wind direction is 12, then you’ll need to set the wind
direction offset to be: 12+180=192.
(17) The rain collector is calibrated at the factory based on the funnel
diameter. The bucket tips every 0.01” or 0.1m of rain (referred to as
resolution). The accumulated rainfall can be compared to a sight
glass rain gauge with an aperture of at least 4” or 0.1m.
(18) Make sure you periodically clean the rain gauge funnel.
Note: The purpose of calibration is to fine tune or correct for any sensor
error associated with the devices margin of error. Errors can occur due to
electronic variation (example, the temperature sensor is a resistive thermal
72
device or RTD, the humidity sensor is a capacitance device), mechanical
variation, or degradation (wearing of moving parts, contamination of
sensors).
Calibration is only useful if you have a known calibrated source you can
compare it against, and is optional. This section discusses practices,
procedures and sources for sensor calibration to reduce manufacturing and
degradation errors. Do not compare your readings obtained from sources
such as the internet, radio, television or newspapers. The purpose of your
weather station is to measure conditions of your surroundings, which vary
significantly from location to location.
NOTE: UV Calibration MUST be performed every 2 to 3 months to
improve results. Over time, UV Index may alter results based on bright and

5.1 Beaufort Wind Force Scale
If you have selected the use of Beaufort wind speed units, you can use the
table below for reference. The Beaufort scale is based on qualitative wind
conditions and how they would affect a ship’s (frigate) sails (so yes, it is an
“old” standard). It is therefore less precise than the other scales but is still in
use in various locales.

5.2 Weather Forecasting
The seven weather icons are Sunny, Partly Cloudy, Cloudy, Rainy, Stormy,
Snowy and Storm Snowy.
The forecast icon is based on the rate of change of barometric pressure.
Please allow at least one month for the weather station to learn the
barometric pressure over time.

temperature≤0℃
5.3 Lightning Alert
The lightning icon will appear if the Dew Point exceeds 70 F. This
means there is a chance of lightning storms forming.
81
5.4 Weather Forecasting Description and Limitations
In general, if the rate of change of pressure increases, the weather is
generally improving (sunny to partly cloudy). If the rate of change of
pressure decreases, the weather is generally degrading (cloudy, rainy or
stormy). If the rate of change is relatively steady, it will read partly cloudy.
The reason the current conditions do not match the forecast icon is because
the forecast is a prediction 24-48 hours in advance. In most locations, this
prediction is only 70% accurate and it is a good idea to consult the National
Weather Service for more accurate weather forecasts. In some locations, this
prediction may be less or more accurate. However, it is still an interesting
educational tool for learning why the weather changes.
The National Weather Service (and other weather services such as
Accuweather and The Weather Channel) have many tools at their disposal
to predict weather conditions, including weather radar, weather models, and
detailed mapping of ground conditions.
5.5 Moon Phase

6 Maintenance
The following steps should be taken for proper maintenance of your station
1. Clean the rain gauge once every 3 months. Rotate the funnel
counter-clockwise and lift to expose the rain gauge mechanism, and
clean with a damp cloth. Remove any dirt, debris and insects. If bug
infestation is an issue, spray the array lightly with insecticide.
Figure 33: Rain gauge installation and maintenance
2. Clean the solar radiation sensor and solar panel every 3 months with a
non-abrasive slightly damp cloth.
3. Replace batteries every 1-2 years. If left in too long, the batteries may
leak due to environmental challenges. In harsh environments, inspect
the batteries every 3 months (while cleaning the solar panel).
4. When replacing the batteries, apply a corrosion preventing compound
on the battery terminals, available at Amazon and most hardware
stores.
5. In snowy environments, spray the top of the weather station with
anti-icing silicon spray to prevent snow build up.

7 Troubleshooting Guide
Look through the following table and locate an issue or problem you are
experiencing in the left column and read possible solutions in the right
column.
Problem
Solution
Wireless remote
(thermo-hygrometer) not
reporting in to console.
There are dashes on the
display console.
The maximum line of sight communication range is about
300’. Move the sensor assembly closer to the display
console.
Resynchronize the remote sensor(s). Reference Section
5.13.2
Install a fresh set of batteries in the remote sensor(s).
Make sure the remote sensors are not transmitting through
solid metal (acts as an RF shield), or earth barrier (down a
hill).
Radio Frequency (RF) Sensors cannot transmit through
metal barriers (example, aluminum siding) or multiple,
thick walls.
Move the display console around electrical noise generating
devices, such as computers, TVs and other wireless
transmitters or receivers.
Outdoor sensor array does not
communicate to the display
console.
The sensor array may have initiated properly and the data is
registered by the console as invalid, and the console must
be reset. Press the reset button as described in Section
Installation.
With an open ended paperclip, press the reset button for 3
seconds to completely discharge the voltage.
Take out the batteries and wait one minute, while covering
the solar panel to drain the voltage.
Put batteries back in and re-sync with console by powering
down and up the console with the sensor array about 10 feet
away.
Bring the sensor array inside the house (you can disconnect
it from the rest of the sensors). The LED next to the battery
85
Problem
Solution
compartment will flash every 16 seconds. If the LED is
not flashing every 16 seconds…
Replace the batteries in the outside sensor array.
If the batteries were recently replaced, check the polarity.
If the sensor is flashing every 16 seconds, proceed to the
next step.
There may be a temporary loss of communication due to
reception loss related to interference or other location
factors,
or the batteries may have been changed in the sensor array
and the console has not been reset. The solution may be as
simple as powering down and up the console.
Replace the batteries in the outside sensor array.
With the sensor array and console 10 feet away from each
other, remove AC power from the display console and wait
10 seconds. Re-connect power.
Temperature sensor reads too
high in the day time.
Make certain that the sensor array is not too close to heat
generating sources or strictures, such as buildings,
pavement, walls or air conditioning units.
Use the calibration feature to offset installation issues
related to radiant heat sources. Reference 5.12.
Absolute pressure does not
agree with official reporting
station
You may be viewing the relative pressure, not the absolute
pressure.
Select the absolute pressure. Make sure you properly
calibrate the sensor to an official local weather station.
Reference Section 5.12 for details.
Rain gauge reports rain when
it is not raining
An unstable mounting solution (sway in the mounting pole)
may result in the tipping bucket incorrectly incrementing
rainfall. Make sure you have a stable, level mounting
solution.
Data not reporting to
Wunderground.com
1. Confirm your password is correct. It is the
password you registered on Wunderground.com.
Your Wunderground.com password cannot begin
with a non-alphanumeric character (a limitation of
Wundeground.com, not the station). Example,
86
Problem
Solution
$oewkrf is not a valid password, but oewkrf$ is
valid.
2.
3. Confirm your station ID is correct. The station ID
is all caps, and the most common issue is
substituting an O for a 0 (or visa versa). Example,
KAZPHOEN11, not KAZPH0EN11
4.
5. If there's a number "1" on the station key, try to i
nput the lower case of letter "L" to replace it.
6. Make sure the date and time is correct on the
console. If incorrect, you may be reporting old
data, not real time data.
7.
8. Make sure your time zone is set properly. If
incorrect, you may be reporting old data, not real
time data.
9.
10. Check your router firewall settings. The console
sends data via Port 80.
No WiFi connection
1. Check for WiFi signal strength symbol on the
display . If wireless connectivity is
successful and reporting to Wunderground.com,
the WiFi icon will be displayed the home
page.
2.
3. Make sure your modem WiFi settings are correct
(network name, password and security settings).
