Ecowitt Weather Station WS90 (WittBoy) - 6-in-1 High Accuracy Weather Station, Piezoelectric Rain Sensor and Sonic Anemometer

TheEcowitt WS90, known as the WittBoy, is one of the most advanced and compact all-in-one weather stations available on the market. Designed to eliminate the shortcomings of traditional weather stations, the WS90 has no moving parts, making it extremely durable over time and easy to maintain. It collects ultra-precise data on wind, rain, temperature and brightness, making it the ideal tool for weather enthusiasts and smart home automation.

Key Selling Points

• Piezoelectric Rain Sensor: Revolutionary in the field, this sensor measures rainfall through haptic vibrations, detecting even the smallest raindrops. Unlike traditional cup rain gauges, it doesn't clog with leaves or dirt and doesn't require periodic cleaning.

• Ultrasonic Anemometer (No Moving Parts): Wind speed and direction are measured by sonic sensors, eliminating the risk of freezing or blocking the rotating cups. This technology provides highly accurate data even during strong gusts or severe winter conditions.

• Comprehensive 6-in-1 Monitoring: The compact unit simultaneously measures: Wind Speed, Wind Direction, Precipitation, Temperature, Humidity and Solar Intensity (including UV index). All data is transmitted in real time to your gateway.

• Built-in Heating System: The station is equipped with a built-in heating element that automatically activates at low temperatures to melt snow or ice from the sonic and piezoelectric sensors, ensuring uninterrupted operation all year round.

• Dual Power: The device utilises a solar panel to charge an internal super-capacitor, providing power during the day. For optimal operation of the rain sensor and heater at night or in winter, the station can be powered via the included DC cable.

• Open Ecosystem and Integration: Data can be published to platforms such as Weather Underground, Ecowitt Weather or integrated into automation systems such as Home Assistant or Shelly (via gateway), allowing smart control of blinds or irrigation depending on the weather.

Examples of Smart Automation

1. High Wind Protection: Set the system to automatically retract awnings or close exterior roller shutters as soon as the sonic anemometer detects gusts over 30 mph.

2. Smart Watering: Automatically stops the garden watering programme if the piezoelectric sensor confirms recent rainfall, saving water and preventing over-watering of plants.

3. Thermal Management: Closes the blinds on the sunny side of the house if the UV index and solar intensity exceed set thresholds, keeping the interior naturally cool.
