Sonoff SWV-BSP: Smart Zigbee 3.0 Water Valve

It installs between the tap and the garden hose in just three minutes with no special tools required, and can be controlled via the eWeLink app, by voice commands, or through fully automated schedules. Powered by four AA batteries with a wireless communication range of up to 130 meters in open space, the SONOFF SWV-BSP smart Zigbee water valve is ideal for lawns, vegetable gardens, flower beds, as well as automatic filling of tanks or swimming pools. A compatible Zigbee 3.0 hub is required.

Customizable Irrigation Plans, Quantitative Watering, and 6-Month Consumption History

The SWV-BSP valve offers two distinct irrigation modes: Schedule Mode for fixed-time watering, and Capacity Mode for automatic shut-off as soon as a predefined volume of water has been delivered. Single or recurring cycles adapt to the specific needs of each garden area, with the option to manually start or stop watering from the app at any time. Water consumption data and irrigation durations are stored for 180 days and can be viewed by day, week, or month to analyze watering habits and eliminate waste.

Weather-Resistant, Local Scenes, and Home Assistant Integration

IP55 certified, the SWV-BSP valve withstands water splashes and dust, featuring a working pressure range between 0.06 and 0.8 MPa (0.6 to 8 bar) that covers standard residential watering setups. Compatible with SONOFF hubs (NSPanel Pro, iHost, ZB Bridge-P, ZB Bridge-U, ZBDongle-E, and ZBDongle-P) as well as Amazon Echo speakers (Plus 2nd Gen, Echo 4th Gen, Echo Show 2nd Gen), it also integrates seamlessly into Home Assistant via Zigbee2MQTT using a ZBDongle for advanced irrigation automations. Smart Zigbee scenes allow, for instance, automatically stopping the watering if a rain sensor detects precipitation or opening the valve according to a preset schedule without manual action. Amazon Alexa and Google Home are also supported for voice control.

 

FAQ

Is the SONOFF SWV-BSP valve compatible with standard European garden taps?

Yes. The SWV-BSP version features a standard European BSP thread (3/4" / 20x27 mm) designed to connect directly between standard outdoor taps and hose fittings.

Can I program a specific water volume instead of a watering duration?

Yes, Capacity Mode allows you to set a target water volume in liters. The valve automatically shuts off once this volume is reached, making it ideal for filling tanks or managing precise water quotas for sensitive plants.

Does the valve work without an internet connection during an outage?

Local schedules and Zigbee local scenes continue to function without internet as long as the devices remain powered and the Zigbee hub is active on the local network. Remote control via the eWeLink app requires an active internet connection.
