Shelly WS90 Ecowitt WS90 7-in-1 Weather Station

The Shelly WS90 (Ecowitt WS90) is a smart, all-in-one outdoor weather station designed to deliver precise, real-time environmental data for home automation, energy optimisation, and weather monitoring. It integrates seven key weather measurements into a single compact unit, combining solid-state sensor technology with seamless smart home connectivity.

Engineered for accuracy and durability, the WS90 features ultrasonic wind measurement and haptic rain detection, eliminating moving parts and significantly reducing maintenance requirements. Its solar-powered design with battery backup ensures continuous operation, while Bluetooth and Zigbee connectivity enable integration with the Shelly ecosystem and third-party platforms.

• 7-in-1 sensor array: wind speed & direction, rainfall, temperature, humidity, UV index, solar radiation, barometric pressure
• Ultrasonic wind sensor (no moving parts) for improved durability
• Haptic rain detection for maintenance-free precipitation measurement
• Dual connectivity: Bluetooth + Zigbee for flexible smart home integration
• Solar-powered with battery backup for reliable outdoor operation
• Compatible with Shelly Smart Control and automation systems (gateway required)
• Designed for real-time monitoring and automation triggers

The WS90 is built to transform environmental data into actionable insights. By combining multiple sensors into a single outdoor module, it simplifies installation while delivering continuous, high-precision measurements across a wide range of weather conditions.

Its solid-state construction—including ultrasonic wind tracking and piezoelectric rain sensing—removes the need for traditional moving components, improving long-term reliability and accuracy. The integrated solar panel supports sustainable operation, while optional external power can activate a built-in heater for cold-weather performance.

The device integrates seamlessly with Shelly smart home systems, enabling users to automate actions such as irrigation, shading, or climate control based on real-time weather data. With support for multiple gateways and platforms (e.g. Zigbee hubs and Home Assistant), it is suitable for both residential and advanced automation setups.
