SONOFF Zigbee Smart Water Valve – Intelligent Irrigation Control for Healthier Gardens

The SONOFF Zigbee Smart Water Valve (SWV-BSP) is a smart irrigation controller designed to automate outdoor watering and help maintain healthier plants while reducing water consumption. Installed directly between your faucet and garden hose, it transforms traditional irrigation systems into intelligent watering solutions with scheduling, water usage monitoring, and Zigbee-based automation.

Designed for gardens, lawns, flower beds, vegetable patches, greenhouses, and other outdoor watering applications, the valve combines easy installation with advanced irrigation management features. With detailed historical records, flexible watering modes, and Zigbee 3.0 compatibility, it provides greater control over watering routines while helping optimize water usage and reduce utility costs.

Key Features

• Quick installation in just minutes
  Simply connect the valve between the faucet and garden hose to upgrade your existing irrigation system. The installation process takes only a few minutes and does not require complex modifications, making it easy to automate outdoor watering.
• Customizable irrigation schedules
  Supports both schedule mode and capacity mode, with options for single or cyclic irrigation programs. Create watering plans tailored to specific plants, lawns, gardens, flower beds, or seasonal requirements.
• Multiple irrigation control modes
  Choose how watering is managed based on time, duration, or predefined water usage targets. Flexible scheduling helps ensure plants receive the correct amount of water without unnecessary waste.
• Up to 6 months of irrigation history
  Review up to 180 days of watering duration and water usage data directly through the app. Historical records can be analyzed daily, weekly, or monthly to identify trends and improve irrigation efficiency.
• Water usage optimization and cost savings
  Detailed data tracking helps identify excessive water consumption and supports more efficient irrigation planning, contributing to lower water bills and responsible resource management.
• Zigbee 3.0 compatibility
  Works seamlessly with Zigbee 3.0 hubs including SONOFF NSPanel Pro, iHost, ZB Bridge-P, ZB Bridge-U, ZBDongle-E, ZBDongle-P, Echo Plus (2nd Generation), and other compatible Zigbee ecosystems.
• Support for open-source platforms
  Easily integrates with advanced smart home platforms through compatible SONOFF Zigbee dongles, enabling customized automation scenarios and advanced irrigation control.
• Smart garden automation
  Combine the valve with weather sensors, soil moisture sensors, schedules, and automation rules to create a fully automated irrigation system that responds intelligently to changing environmental conditions.
• Reliable remote control and monitoring
  Manage watering schedules, monitor irrigation activity, and review historical statistics remotely through supported smart home applications.

Frequently Asked Questions (FAQ)

1. Can BSP and NH specifications be mixed?

No, they cannot be mixed.

2. What is the difference between the two specifications?

(The detailed differences can be provided separately if needed.)

3. Does the water valve affect the original water flow rate?

Yes, but only slightly.

4. How long does the device's battery last?

Assuming the device runs 1 hour per day and remains in standby mode for the rest of the time, the estimated battery life is 20 months (calculated based on laboratory power consumption data).

Note: The SWV device does not include batteries; users need to provide their own. The above estimate is based on a 2800mAh battery. Actual battery life depends on battery capacity and usage habits.

5. The gateway shows the latest firmware version, but the SWV does not have all functions. Why?

Please check if the SWV was added to the gateway before upgrading the gateway firmware to the latest version.

If so, you need to remove the SWV device and add it again after the gateway upgrade to enable full device functionality.

6. Does the device automatically shut off when water runs out?

Yes. If the device detects water shortage and remains turned on, it will automatically shut off after 30 minutes of continuous water shortage.

7. What functions does the device support in ZHA and Z2M?

In ZHA, only water valve open/close control is supported.

In Z2M, after upgrading the device firmware to version 1.0.3 or above, it supports:

• Water valve open/close.
• Flow detection.
• Scheduled and volume-based irrigation.

8. Can the device be used in low-temperature (freezing) environments?

No, SWV cannot be used in freezing conditions. The operating temperature range is 5°C to 60°C.

In freezing weather, the water inlet/outlet may freeze, preventing normal valve control and flow measurement. It is recommended to bring the SWV indoors during winter and only use it when temperatures warm up.

9. Will unstable water pressure affect irrigation volume measurement?

No. When water pressure fluctuates, the flow rate changes accordingly. SWV calculates irrigation volume based on the actual flow rate.

10. Why is horizontal installation not recommended?

Horizontal installation affects the flow sensor, causing inaccuracies in irrigation volume calculation. Please install the device vertically.
