3. Setup
3.1 Unpacking and Placement
Carefully remove all components from the packaging. Place the WN1821 console in a central location within your home, away from direct sunlight and heat sources, to ensure accurate indoor readings. Ensure it is within range of your Wi-Fi network and any external sensors.
3.2 Powering the Device
- Connect the provided Type-C power cord to the console and a suitable power adapter.
- For emergency backup, insert 2 x AA batteries into the battery compartment, observing correct polarity.
3.3 Wi-Fi Configuration
The WN1821 console requires Wi-Fi connectivity to upload data to online platforms and the Ecowitt app. Follow the instructions provided in the ECOWITT View app or visit the Ecowitt website for detailed Wi-Fi configuration steps. This process typically involves connecting your mobile device to the console's temporary Wi-Fi hotspot and then configuring it to connect to your home Wi-Fi network.
3.4 Sensor Pairing (Optional)
If you are using additional Ecowitt sensors, ensure they are powered on and within the console's transmission range (30 meters, 915 MHz frequency). The console will automatically detect and display data from compatible sensors. Refer to the individual sensor manuals for specific pairing instructions.

4. Operating Instructions
4.1 Understanding the Display
The LCD display provides real-time data. Use the touch buttons on the console to navigate through different display modes and view various parameters such as time, indoor/outdoor temperature and humidity, CO2 levels, wind speed, wind direction, precipitation, and barometric pressure. The console primarily displays wind, rain, outdoor temperature, and humidity. Other detailed or 'hidden' data, such as multi-channel sensor readings, can be accessed through the ECOWITT View app or the Ecowitt website dashboard.
4.2 Data Access and Online Platforms
Once connected to Wi-Fi, your WN1821 console will upload data to the Ecowitt server. You can view this data, historical trends, and receive email alerts through your account on the Ecowitt website. Additionally, the console supports publishing data to third-party weather platforms like Weather Underground, Weather Cloud, and WOW.

4.3 Unit Adjustment and Backlight
The console allows for adjustment of measurement units (e.g., Celsius/Fahrenheit, km/h/mph) and backlight brightness. Refer to the on-screen menu or the ECOWITT View app for specific steps to modify these settings.
5. Maintenance
5.1 General Care
Keep the console clean and dry. Avoid exposing it to extreme temperatures, direct sunlight for prolonged periods, or corrosive materials. Ensure proper ventilation around the device.
5.2 Cleaning
Wipe the display and casing with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these may damage the surface or internal components.
6. Troubleshooting
6.1 No Display/Power
- Check if the Type-C power cord is securely connected to both the console and the power source.
- Verify that the power adapter is functioning correctly.
- Ensure the AA backup batteries are correctly inserted and not depleted.
6.2 No Sensor Data
- Compatibility: Ensure your external sensors operate on the 915 MHz frequency, which is required for compatibility with the WN1821 console in North America. Sensors designed for other regions (e.g., 433 MHz for international versions) will not communicate with this console.
- Check that external sensors are powered on and have fresh batteries.
- Ensure sensors are within the console's transmission range (30 meters) and there are no significant obstructions.
- Try re-pairing the sensors according to their respective manuals.
6.3 Wi-Fi Connection Issues
- Verify your Wi-Fi network is active and broadcasting on 2.4 GHz (802.11 b/g/n). The console does not support 5 GHz networks.
- Ensure the Wi-Fi password is entered correctly during configuration.
- Move the console closer to your Wi-Fi router to improve signal strength.
- Restart your Wi-Fi router and the WN1821 console.
