Product detailed description

🚰 Get a perfect overview and keep your water under control

The Shelly Neo smart water valve is a professional device designed for drinking water systems, featuring ultrasonic measurement technology, remote control, and automatic water leak protection. This brass valve (DN25) with NSF certification is ideal for apartments, cabins, offices, or commercial buildings where water consumption monitoring, remote intervention capabilities, or irrigation control are required.

The device measures water flow, pressure, temperature, and total consumption in real time. Thanks to the ultrasonic measurement system, it contains no mechanical parts subject to wear and tear. This ensures a long lifespan, high accuracy, and minimal maintenance requirements. Enjoy an accuracy of ±0.1 gal (0.38 l) for flow, ±1 kPa for pressure, and ±0.5 °C within a range of -10 °C to 65 °C. The measured data can be viewed in detailed daily, weekly, or monthly graphs in the Shelly Smart Control app. Monitor water temperature in °C or °F, flow and total consumption in liters, gallons, m³, or ft³, and pressure data in PSI, kPa, or bars.

Thanks to Shelly's collaborative platform, the Neo smart water valve supports connection via 2.4 GHz or 5 GHz Wi-Fi, and using Bluetooth 5.0, you can quickly add it to your system – without the need for a separate hub. In collaboration with the Shelly ecosystem, it can automate irrigation, optimize water consumption, and provide leak protection. When paired with the Shelly Flood sensor, the system can automatically shut off the water supply if a leak is detected.

The device features a fast opening and closing mechanism, ensuring immediate response to manual control or automation. A local web interface and MQTT support allow for full local integration with advanced automation systems.

Set custom alerts for temperature, pressure, or consumption, and choose how the valve should behave after a power restoration. You can use the physical button for quick manual control at any time.

The device is designed with an emphasis on maximum durability and long-term operation. The high-quality brass construction with NSF certification and an IPX7 protection rating guarantees safe and reliable operation in drinking water distribution systems as well as in demanding humid environments.

The Neo smart water valve is particularly useful for applications such as remote control of water supply, supervision of recreational properties or rentals, precise irrigation automation, detection of unusual water consumption patterns, and prevention of water damage due to leaks.
