5 Set up Guide
5.1 Pre Installation Checkout
To complete assembly you will need a Philips screwdriver (size PH0) and a
wrench (size M5; 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
5.2 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,

9
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 2: Sensor assembly detailed items
5.3.1 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 2 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 2.

11
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 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.
5.3.2 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 4. 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

12
of friction, which is helpful in providing steady wind direction
measurements.
Figure 4: Wind vane installation diagram
5.3.3 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 5 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 5: Wind speed cup installation diagram
5.3.4 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

13
batteries and start over, but if you see the flash once every 16 seconds,
everything should be OK.
Figure 6: 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.
5.3.5 Mount assembled outdoor sensor package
5.3.5.1 Before you mount
Before proceeding with the outdoor mounting detailed in this section, you
may want to skip to setup instructions in section 5.5 and onwards first, while
you keep the assembled outdoor sensor package nearby (although preferably
not closer than 5 ft. or 1.53m 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.

14
5.3.5.2 Mounting
You can attach a pipe to a permanent structure and then attach the sensor
package to it (see Figure 7).
The U-Bolts will accommodate a pipe diameter of 1-2 inches (pipe not
included).
Figure 7: 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.

15
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”
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 6.9.2 ).
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.

16
Doing so is also important to avoid false registration of these
readings with weather services.
5.3.6 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 8) 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.
Figure 8: Reset button and Transmitter LED location
5.4 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:
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).

17
Line of Sight Rating. This device is rated at 300 feet or 100 meter 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 or 30 meter.
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.
Medium

5-15%
Plastics
10-15%
