Setup Guide
1. Unpacking and Initial Inspection
Carefully remove all components from the packaging. Inspect for any signs of damage. If any parts are missing or damaged, contact customer support.
2. Installing Batteries
The main console and outdoor sensor require batteries (not included). Insert the correct type and number of batteries into each unit, observing polarity.
- Main Console: Refer to the battery compartment for specific requirements (e.g., AA or AAA batteries).
- Outdoor Sensor: Refer to the battery compartment for specific requirements. Ensure the battery compartment is sealed properly after installation to protect against weather.
3. Mounting the Outdoor Sensor
The 7-in-1 outdoor sensor should be mounted in an open area, away from obstructions, to ensure accurate readings for wind, rain, temperature, and UV. Consider the following:
- Height: Mount at a height that allows for accurate wind measurement, typically 2-3 meters (6-10 feet) above ground.
- Clearance: Ensure no trees, buildings, or other structures block wind flow or rain collection.
- Sunlight: The solar panel on the outdoor sensor requires direct sunlight for optimal performance and battery charging.
- Orientation: Orient the wind direction vane correctly, usually pointing North.

4. Powering On the Main Console
After installing batteries, the main console should power on automatically. If not, check battery installation or connect the power adapter.
5. Sensor Synchronization
The main console will automatically attempt to connect with the outdoor sensor. This process may take a few minutes. Ensure both units are within the specified transmission range (up to 100m / 328 feet).
Operating Instructions
1. Display Overview
The main console features a 7.48-inch color screen displaying various weather parameters. Key indicators include:
- Network Forecast
- Rainfall (current, hourly, daily)
- Wind Speed and Direction
- Outdoor Temperature and Humidity
- Indoor Temperature and Humidity
- UV Index

2. Wi-Fi Connectivity and App Integration
The ZWS390 Weather Station supports Wi-Fi connectivity for data transfer and remote monitoring via a smartphone application.
- Download the App: Search for and download the "WeatherSense" app (or similar, as indicated by the image) from your device's app store.
- Create an Account: Register for a new account within the app.
- Connect to Wi-Fi: Follow the in-app instructions to connect your main console to your 2.4GHz Wi-Fi router. The device will typically be named "W003" during the setup process.
- Data Upload: Once connected, the weather station will upload data to the app, allowing you to view current and historical weather information remotely.

3. Understanding Weather Forecasts
The station provides a 12-hour weather forecast based on barometric pressure changes. Icons represent various conditions:
- Sunny
- Cloudy
- Rainy
- Snowy
- Hail
- Storm
Note: The accuracy of a general pressure-based forecast is approximately 70-75%.
