1. Introduction
Thank you for your purchase of the Solar Powered Wireless WiFi 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 out 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.
Required
Step Description Section
1 Assemble and power up the outdoor sensor 5.2.1 – 5.2.3
2 Power up the display console and synchronize with the outdoor
sensor
5.3
5 Mount the sensor array 5.2.5
3 Set date and time on console 6.3.1
4 Calibrate the relative pressure to sea-level conditions (local airport)
on console
6.7
6 Reset the rain to zero on console 6.4.10
Optional
7 Configure WiFi 8
8 Register and upload to Weather Server 8
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
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 rechargeable
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’ 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 330 feet, 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 100’.
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.

on the wind vane and push the vane on to the shaft. (b) tighten the set screw with the hex
wrench (included).

5.2.3 Install Batteries
Reference Figure 6. Locate the battery door on the bottom of the sensor array. Turn the
set screw counter clockwise to open the battery compartment. Insert the 3xAA
rechargeable batteries (included). The LED indicator on the bottom of the sensor array will
turn on for four seconds and normally flash once per 16 seconds (the transmission update
period).
Close the battery door and tighten the set screw.

5.2.4 Mount Weather Station
There are two methods for attaching your weather station:
A. Option 1: Mounting Clamps. Fasten the mounting pole to your mounting pole or
bracket (purchased separately) with the two U-bolts, mounting pole brackets and nuts, as
shown in Figure 7. Tighten the mounting pole to your mounting pole with the U-Bolt
assembly. Make sure your mounting pole is as far away from the temperature sensor as
possible, as shown in Figure 7.

10
Figure 7
B. Option 2: Swedged Pole Mount. Insert the swedged end of the included
mounting pole into the open end of any standard mounting pole solution (1 3/8”
diameter) available from Ambient Weather, as shown in Figure 8. For more
information on mounting solutions, visit:
http://www.ambientweather.com/amwemoso.html

1. Reference Figure 9. Locate the four wind vane compass rose indicators of N, E, S,
W (representing North, East, South and West). Align the compass rose direction
upon final installation with a compass or GPS.

2. Reference Figure 10. Make sure the sensor array is completely level upon final
installation. Failure to do so will result in inaccurate rain gauge readings.

5.2.5 Reset Button and Transmitter LED
In the event the sensor array is not transmitting, reset the sensor array.
With an open ended paperclip, press and hold the RESET BUTTON for three 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 resynchronize with the ObserverIP receiver by powering down
and up the ObserverIP receiver with the sensor array about 10 feet away.

5.3 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 sensor flat.
Wireless communication is susceptible to interference, distance, walls and metal barriers.
We recommend the following best practices for trouble free wireless communication.
1. Electro-Magnetic Interference (EMI). Keep the console several feet away from
computer monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 433 MHz devices and
communication is intermittent, try turning off these other devices for
troubleshooting purposes. You may need to relocate the transmitters or receivers
to avoid intermittent communication.
3. 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.
4. 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.
Medium RF Signal Strength Reduction
Glass (untreated) 5-15%
Plastics 10-15%
Wood 10-40%
Brick 10-40%
Concrete 40-80%
Metal 90-100%

5.4 Display console
1. Insert the 5V AC 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 3 AAA batteries into the display console (optional).
3. Keep both sensor and the display console together for 15 minutes to lock in the
sensor signals.
4. (Optional)-Spin the wind cups to simulate wind speed. Take the sensor to the sink and
slowly drip water into the rain bucket to simulate rain.
5. After 15miuntes, follow the mounting instructions for proper placement of sensors.
Note: Your display console should have readings in all sections. Wind and Rain will
show 0’s (connected) until wind or rian occur or are simulated.
Note: If you only use battery to power up display console, you must press
LIGHT/SNOOZE key to light up the LCD before press any other key.
