The Shelly–Ecowitt WS90 7-in-1 weather station measures wind (with an ultrasonic anemometer), rain (with a piezo/haptic rain sensor), temperature, humidity, sunlight, and UV index in a single compact outdoor sensor unit—so you can use accurate, real-time weather data for monitoring and automations. Solar power with a built-in supercapacitor and AA battery backup ensures year-round operation, while the IPX5 rating makes it resistant to the elements.
Integrated into the Shelly ecosystem, the WS90 provides real-time solar radiation, wind, and temperature data, enabling automation of blinds/shades, optimization of heating and cooling, and timely alerts for high winds, showers, or elevated UV exposure. Zigbee and Bluetooth operate simultaneously, delivering a stable mesh and easy pairing.
Its design with no moving parts requires little maintenance and remains reliable over the long term. It’s an ideal choice for home users and advanced automation projects alike whenever precise outdoor data is needed.
About Ecowitt
Ecowitt is a brand specialized in professional and home weather-measuring systems. Its sensors deliver accurate, stable data that can be integrated with numerous platforms and gateways, while the WS series uses modern, low-maintenance technologies (e.g., ultrasonic wind measurement).
Key features
- 7-in-1 sensor array: ultrasonic wind speed/gust/direction, piezo (haptic) rain detection, temperature, humidity, illuminance, and UV index.
- Dual connectivity: Zigbee and Bluetooth run concurrently for easy setup and reliable automations.
- Solar operation with backup: integrated solar panel + supercapacitor, AA battery backup for continuous operation.
- Low maintenance: solid-state sensors with no moving parts; outdoor IPX5 protection.
- App visualization and alerts: data and trends in Shelly Smart Control; threshold alerts for high winds, precipitation, or high UV.
Smart home protocols and platform compatibility
- Wireless connection: Zigbee + Bluetooth (simultaneously).
- Compatible gateways/app: To use Shelly Smart Control, a gateway is required—Shelly BLU Gateway or any Shelly Plus / Pro / Gen3 / Gen4 device (except sensors). The WS90 can also be coordinated over Zigbee with other Zigbee hubs (features vary by hub).
- Local automations: run scenes on Shelly devices to control blinds, shades, relays, or HVAC based on WS90 data.
Smart functions
- Weather-based scenes: shading under strong radiation, retracting awnings in wind, notifications when it rains.
- Energy optimization: fine-tune heating/cooling based on outdoor temperature, wind, and irradiance.
- Live trends and early indicators: act proactively based on pressure and wind trends (e.g., securing outdoor furniture).
