1. Introduction
Thank you for your purchase of the Ambient Weather WS-2902D Wi-Fi OSPREY Solar-Powered Wireless Weather
Station. The following User Guide provides step-by-step instructions for installation, operation, and troubleshooting.
The product is continuously changing and improving, particularly online services and associated applications.
To download the latest manual and for additional help, please visit:
https://ambientweather.com/faqs/question/tags/tag/WS-2902D/
1.1 Product History
•WS-2902: Initial product release. Used Ambient Tool app for WiFi setup.
•WS-2902A: Added Wi-Fi broadcast mode. This enables users to connect their console to their dual band router
without having to disable the 5.0 GHz band.
•WS-2902B: Supports 8-channel thermo-hygrometer sensors and PM2.5 sensors. They cannot be viewed on the

Version 1.29 ©Copyright 2022, Ambient LLC. All Rights Reserved. Page 6
display console but are passed through to the Ambient Weather Network.
•WS-2902C: Improved console layout.
•WS-2902D: Console layout improved. Web GUI Wi-Fi setup interface added. Wi-Fi connectivity enabled;
Awnet app no longer needed from the App Store/ Google Play Store.
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: 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.
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.
Warning: Only install the weather station on a clear, dry day.

4.4 Wind Vane Installation
Reference Figure . (a) Locate and align the flat key on the Wind Vane Shaft to the flat key on the Wind Vane and push
the vane on to the shaft. (b) Tighten the set screw with a Precision Screwdriver and make sure the Wind Vane spins freely.
Note: You may need to back out the set screw first before sliding the vane onto the shaft.
Note: The Wind Vane shaft does not spin as freely as the Wind Cups. This is by design; the dampening prevents the
Wine Vane from spinning with the slightest breeze, which will result in variable wind all the time. The added resistance
allows the Wind Vane to change direction with 2 – 3 mph, providing much better wind direction tracking.

4.5 Wind Cup Installation
Reference Figure . (a) Push the Wind Cups onto the shaft. (b) Tighten the set screw with a Precision Screwdriver and
make sure the Wind Cups spin freely.
Note: You may need to back out the set screw first before sliding the cups onto the shaft.

4.6 Rain Gauge Funnel Installation
Reference Figure . Install the Rain Gauge Funnel. Rotate clockwise to attach the funnel to the Sensor Array.

4.7 Funnel Coil Filter Installation
To install the Funnel Coil Filter, press the coil until the hook is inside the hole at the bottom of the funnel and locked in
place. The spring tension will keep the filter sitting tightly on the funnel.
Figure 5
4.8 Battery Installation
Reference Figure . Insert (2) AA non-rechargeable batteries (not included) into the battery compartment. The LED
indicator on the back of the transmitter will turn on for four seconds and then flash once every 16 seconds (the sensor
transmission update period).
(a)
(b)
Figure 6
Note: If the LED does not light up or stays on permanently, make sure the battery polarity is correct and that the

Version 1.29 ©Copyright 2022, Ambient LLC. All Rights Reserved. Page 10
batteries are fresh. Do not install the batteries backwards. You can cause permanent damage to the Thermo-Hygrometer.
Note: We recommend lithium batteries for cold weather climates, but alkaline batteries are sufficient for most
climates. We do not recommend rechargeable batteries. They have lower voltages, do not operate well at wide temperature
ranges, and do not last as long, resulting in poorer reception.
5. Display Console
The front and back of the Display Console is shown in Figure 7 and Figure 8.

Figure 8
Reference Figure .
(1) Connect the Display Console power jack, using the included AC Power Adapter.
(2) Unfold the desk stand and place 5 to 10 feet away from the Sensor Array. Remove the battery door on the back

Version 1.29 ©Copyright 2022, Ambient LLC. All Rights Reserved. Page 11
of the console and insert (3) AAA batteries, per Figure .
(3) Wait several minutes for the remote sensors to synchronize with the Display Console.
(4) Weather station MAC address location.

6. Vertical Desk Stand
The console is best viewed above from a 20-degree to 30-degree angle. In addition to the fold-out desk stand on the back
of the Display Console, the console also includes a vertical desk stand to improve the viewing ability on a desk, as shown
in Figure .

7. Console Initialization
After the console is connected to AC power, the console will display the software version number.
Figure 11
The console will display all of the LCD segments for three seconds after power-up, as shown in Figure . The indoor
conditions will immediately update, and the outdoor Sensor Array will register within a few minutes.

9. Connecting the Weather Station Console to Wi-Fi
Note: The console broadcasts a 2.4 GHz signal. If you own a dual-band router (2.4 GHz and 5.0 GHz), make sure
your router’s 2.4 GHz band is on. You are not required to turn off the 5.0 GHz band.
Note: When first powered on (~5 min) the console broadcasts it’s own WiFi network named “AMBWeatherPro-
######”. When attempting to connect to WiFi after the initial 5 min broadcast, press and hold both the Wind/+ and
Pressure/- buttons on the front of the display for 5-10 seconds the follow the steps in 9.1 (below).
