2.2. WS3800 7.5'' LCD IoT-Supported Console
The WS3800 console features a 7.5-inch LCD display and includes built-in indoor temperature, humidity, and barometric pressure sensors. It supports connection to a 2.4 GHz Wi-Fi network, allowing data viewing from anywhere via phone, tablet, or computer browser. The console functions as both a Wi-Fi gateway for Ecowitt sensors and an IoT gateway for pairing with up to 16 Ecowitt IoT devices (e.g., WFC01 watering timer, AC1100 smart outlet plug, sold separately).

4.2. Sensor Data Display Priority
If multiple compatible sensors are connected, the WS3800 console prioritizes data display as follows:
- Outdoor Temperature and Humidity: WN32 > WS90 > WS80 > WS69
- Wind Speed/Direction: WS90 > WS80 > WS68 > WS69
5. Sensor Compatibility
The WS3800 display console can pair with various Ecowitt sensors (sold separately) to expand its monitoring capabilities. Some sensor data can be displayed directly on the console, while others are uploaded exclusively to the cloud server.
5.1. Sensor Data Displayed on WS3800
- WS90 outdoor compact sensor array (temperature, humidity, light, UV, wind speed/direction, rainfall)
- WS80 ultrasonic anemometer sensor (outdoor temperature, humidity, light, UV, wind speed/direction, rainfall)
- WS68 anemometer sensor (light, UV, wind speed/direction)
- WH40 rain gauge sensor (rainfall)
- WN32 outdoor thermo-hygrometer sensor (outdoor temperature and humidity)
- WN32P indoor thermo-hygrometer-barometric pressure sensor (indoor temperature, humidity, and pressure)
- WH45/WH46 air quality sensor (CO2, PM1.0, PM2.5, PM4.0, PM10, temperature and humidity)
- WN31/WN30/WN36 sensors (temperature and humidity, pool temperature)
- WFC01 smart water timer
- AC1100 smart plug
5.2. Sensor Data Uploaded Only to Cloud
- WH57 lightning detector sensor
- WH41/WH43 PM2.5 detector sensors

6.2. RF Frequency
The system operates on an RF frequency of 915 MHz for communication between the outdoor sensor and the indoor console.
7. Maintenance
To ensure optimal performance and accuracy of your weather station, regular maintenance is recommended:
- Clean Sensors: Periodically clean the rain collector, wind cups, and wind vane to remove debris that may affect readings.
- Check Batteries: Replace batteries in the outdoor sensor array as needed, especially before winter months.
- Clear Obstructions: Ensure the outdoor sensor array remains free from any physical obstructions that could impede wind flow or rain collection.
- Console Cleaning: Wipe the display console with a soft, dry cloth. Avoid abrasive cleaners.
8. Troubleshooting
If you encounter issues with your ECOWITT Weather Station, consider the following common troubleshooting steps:
- No Data Displayed: Check that both the outdoor sensor and indoor console have power. Ensure they are within the 100m/33ft transmission range and that there are no major obstructions. Re-pair the sensors if necessary.
- Wi-Fi Connectivity Issues: Confirm your router is operating on a 2.4 GHz frequency. If you have a dual-band router, temporarily disable the 5 GHz band during initial setup. Ensure correct Wi-Fi password entry.
- Inaccurate Rain Readings: Ensure the rain collector is level and free of debris. Note that tilting the sensor during installation or maintenance may register false rain data that cannot be reset from the console.
- Console Buttons Unresponsive: Check power supply. If using batteries, ensure they are fresh and correctly inserted.
For more detailed troubleshooting, refer to the comprehensive user manual available on the ECOWITT website or contact customer support.
