Smart Irrigation Solenoid Valve Sonoff Hydro One BSP (SWV-ZFE-BSP) – Zigbee 3.0 Connectivity, Brass Inlet Fitting (BSP), Water Flow Measurement, IP55 Protection

Description

Sonoff Hydro One BSP (SWV-ZFE-BSP) is the new solution in the Sonoff Hydro Series range, created specifically for durable automation of residential irrigation systems. The SWV-ZFE-BSP model comes natively configured with a European-pitch thread (BSP), and is equipped at the inlet with a solid brass nut, designed to withstand high pressures, repeated fitting and mechanical wear, eliminating the risk of cracking or damage to the thread typical of plastic fittings.

Equipped with a high-precision built-in flow meter, the solenoid valve lets you control water consumption to the litre, prevent waste and receive instant notifications in the event of anomalies such as no water in the supply. Thanks to the Zigbee 3.0 protocol, the device offers a minimal response time, low power consumption and extended coverage in the home mesh network.

Key Features & Technical Advantages

• Robust Brass Fitting (European BSP Standard): The tap connection thread (G3/4") is made of premium-quality brass, ensuring a watertight joint that is resistant to pressure surges and extreme temperature variations.

• Consumption Measurement and History (Built-in Flow Meter): Measures the exact volume of water used in each watering session. In the app you can set mixed automations: stopping watering after a set duration (minutes) or after a fixed quantity of water (litres) has been reached.

• Smart Irrigation Modes in eWeLink: Supports two main operating modes:

  • Irrigation by volume (Capacity Irrigation): Automatically shuts off the water once the target volume of water has been delivered.

  • Timed Irrigation: Works based on time intervals and a preset duration.

• No-Water Alert and Blockage Protection: The device detects whether the main tap is closed or the water pressure has dropped below the operating limit, sending a warning push notification to your phone.

• IP55 waterproof construction: The sealed housing protects the electronic components and the battery compartment against torrential rain, direct splashes and UV rays.

• Universal Zigbee 3.0 Compatibility: It integrates directly with Sonoff hubs (NSPanel Pro, ZB Bridge-P/U, iHost), as well as with open systems such as Home Assistant (via ZHA or Zigbee2MQTT), Hubitat or SmartThings.

Ways to Use It and Scenarios

1. Fixed-Volume Watering (Water Saving): Program the solenoid valve to deliver exactly 30 litres of water to the drip system in the greenhouse, ensuring optimal plant hydration without waste.

2. Scheduled Lawn Irrigation: Set up an automatic lawn watering schedule every morning at 05:30 for 15 minutes, before the sun scorches the leaves.

3. Smart Automation with a Weather Sensor (Home Assistant): Create an advanced rule in Home Assistant that cancels the irrigation cycle if the local rain sensor has recorded rain in the last 6 hours.

Package Contents

• 1 × Sonoff Hydro One BSP smart solenoid valve (SWV-ZFE-BSP)

• 1 × Outlet quick adapter/connector

• 1 × Roll of Teflon sealing tape

• 1 × User manual and eWeLink / Zigbee setup instructions

Practical use cases

• Mounted on the garden tap, it delivers a fixed amount of water (in litres) to the drip system in the greenhouse, then stops watering automatically.
• Set with up to 6 watering programmes, it waters the lawn early in the morning, for the preset duration, without manual intervention.
• Sends a notification to your phone if the main valve is closed or there is no water, so that the irrigation cycle is not missed.

Technical specifications:

SWV-ZFE is the ideal choice for anyone who wants automatic irrigation, controlled remotely and with exact measurement of the water used.
