SmartWise's one-way smart motorised water valve is a remotely controllable smart device for closing and opening water pipes. Just as Sonoff devices, it works with eWeLink app, so it can be connected to Sonoff / eWeLink automations. It is equipped with a built-in Wi-Fi chip, which allows you to connect the device directly to your Wi-Fi router, no smart home hub is required.

Just as Sonoff and other SmartWise devices, it is compatible with the free eWeLink app, available for Android and iOS smart phones, so it works well together with Sonoff smart devices.

From an Android or iOS smartphone with an internet connection (Wi-Fi or cellular), you can remotely open and close it at any time from the eWeLink app, and of course monitor its current status (open = ON or closed = OFF). As with all other eWeLink devices, we can also open/close as a scheduled action, supports timer or as a loop action.

You can also set the default state after a power outage (open/closed/pre-power outage state) in the eWeLink app.

Sonoff / eWeLink automations (scenes) can be used to automatically shut off water in the event of an unexpected flood triggered by, for example, an alert from a SmartWise water leak sensor or a SmartWise Zigbee Flood water leak sensor.

It is powered by a 5V DC power supply, which is included with the product.

Operating at a maximum working pressure of 16 bar (at 1-70℃), the motorised smart valve is available in DN15 (1/2" coll), DN20 (3/4" coll) and DN25 (1" coll) versions.
