Shelly Ecowitt WS90 7-in-1 Outdoor Weather Station — Zigbee & Bluetooth, Ultrasonic Wind and Haptic Rain

Compact and weatherproof, the WS90 combines seven environmental measurements into one outdoor unit. It reports temperature, humidity, wind speed and direction, rainfall, UV index and illuminance with long-range wireless transmission and optional integration into the Shelly Smart Control ecosystem. Designed for year-round outdoor use, the WS90 pairs with Shelly gateways or compatible Zigbee hubs to feed real-time data to apps, automation rules, and irrigation controllers.

How accurate and reliable are the WS90 sensors?

The WS90 uses ultrasonic wind sensing and a haptic rain detector to minimize moving parts and mechanical wear, which improves long-term accuracy. Thermal insulation and IPX5 waterproofing help the sensor remain stable across temperature swings and wet conditions.

• Ultrasonic wind monitoring for precise speed and direction without cups or vanes
• Haptic rain detection measures rainfall volume and detects start/stop events
• Built-in solar panel with backup batteries for continuous operation
• IPX5-rated housing and thermal materials for outdoor durability

Can I connect the WS90 to my Shelly system or other smart hubs?

Yes — the WS90 supports both Bluetooth and Zigbee to integrate with Shelly BLU Gateway and Shelly Plus/Pro/Gen3/Gen4 devices or third‑party Zigbee hubs. A gateway or compatible hub is required to view data in the Shelly Smart Control app and to use automation features.

• Bluetooth and Zigbee dual connectivity for flexible setup options
• Requires Shelly BLU Gateway or a Zigbee-compatible controller for app access
• Feeds sensor readings into Shelly automations, including irrigation rules
• Long-range transmission up to 150 m (500 ft) with obstacles, 300 m (1,000 ft) open

How does the WS90 help with watering and garden care?

The WS90 supplies precise rainfall, humidity, wind, and UV readings so you can avoid overwatering and protect plants from high winds or intense sun. When paired with Shelly irrigation controllers, these inputs let you skip scheduled watering after rain or adjust durations based on current conditions.

• Automatic skip rules when recent rainfall exceeds set thresholds
• Humidity and wind data to fine-tune sprinkling times and durations
• UV and light metrics to plan shade, fertilization, or seasonal adjustments
• Works with Shelly irrigation controllers for end-to-end automation

What should I know about installation and maintenance?

Mounting is straightforward and the WS90 is designed for low maintenance thanks to its non-mechanical sensors. Place it in an unobstructed outdoor spot for best wind and rain readings, and ensure the solar panel gets some light for battery charging.

• Simple mount with recommended clear exposure for wind and rainfall
• Solar charging plus backup batteries reduces service visits
• Recommended: pair with a Shelly BLU Gateway or Zigbee hub during setup
• No routine calibration needed thanks to ultrasonic and haptic sensors

Who is this for? The Shelly Ecowitt WS90 is ideal for homeowners, small‑scale gardeners, greenhouse operators and hobby farmers who want accurate, low‑maintenance outdoor weather data that integrates into smart home or irrigation systems. It suits users who prioritize long-term reliability, automated watering savings, and compatibility with the Shelly Smart Control ecosystem. Shelly offers professional customer support and a two-year device warranty for peace of mind.
