SONOFF SWV-BSP - Zigbee 3.0 Smart Water Valve

Presentation

The SONOFF Smart Water Valve (SWV) transforms your traditional irrigation system into a smart connected installation. Powered by four standard AA batteries, this valve is quickly installed on any standard faucet thanks to its universal threaded connector, without the need for electrical wiring or complex modifications.

Control your garden watering from anywhere via the eWeLink app: schedule precise irrigation times, set repetitive cycles, configure specific water quantities, or create smart automations combining weather sensors and other smart devices. The system automatically records water consumption with a history kept for free for 6 months.

Its IP55 waterproof design withstands water splashes and weather for permanent outdoor installation. The robust black PC+ABS case integrates a local manual control button, a tricolor LED connection status indicator, and a battery compartment accessible without tools. A 130-meter Zigbee range in open field ensures reliable coverage even when far from the gateway.

Key Functions

• Installation without wiring 4 AA batteries: Eliminate electrical constraints by powering the valve with standard replaceable batteries available everywhere, allowing flexible installation on outdoor faucets far from any power outlet.
• Multifunctional scheduled watering: Set timed irrigation for daily morning watering, weekly repetitive cycles adapted to each garden zone, or quantitative irrigation stopping automatically after a defined volume for precise water savings.
• Real-time water consumption tracking: Instantly visualize the amount of water used during each watering and consult free 6-month historical graphs to identify excessive consumption, optimize irrigation durations according to seasons, and significantly reduce the water bill.
• Smart weather automations: Pair the valve with rain, temperature, or soil humidity sensors to trigger watering only when necessary, cancel scheduled irrigation in case of detected precipitation, or adjust volumes according to weather to avoid waste and over-watering.
• Hands-free voice control: Activate or deactivate watering instantly with simple voice commands "Alexa, open the garden valve" or "Ok Google, stop watering" without using a smartphone, convenient for wet or busy hands.
• Remote control for vacation peace of mind: Monitor and manage irrigation even when traveling, start emergency watering during heatwaves, receive alerts if the valve remains open abnormally long, preventing costly leaks or floods.
• Quick standard faucet mounting: Simply screw the inlet nut onto the existing faucet after applying sealing Teflon, then connect the hose to the valve outlet in less than 5 minutes without a plumber or specialized tools required.
• IP55 outdoor waterproof protection: Install the valve outside exposed to rain and sun without fear thanks to IP55 certification ensuring resistance to water jets and dust, durable PC+ABS material supporting UV and temperatures from 5-60°C year-round.
• Instant status LED indicator: Identify connection status at a glance with a solid green LED (normally connected), slow blinking (pairing in progress), or rapid blinking (gateway connection problem requiring intervention).
• Local manual emergency control: Activate or deactivate the valve with a simple press of the physical button directly on the case in case of smartphone unavailability, internet outage, or need for quick functionality testing without an app.
• Complex multi-zone scenarios: Orchestrate sequential irrigation of multiple valves automatically chaining lawn watering, then vegetable garden, then flowerbeds with optimized intervals avoiding simultaneous water pressure drop and ensuring uniform distribution.
• Professional 130m Zigbee range: Cover large gardens up to 130 meters between the gateway and valve in open space, or extend unlimited range via additional Zigbee routers for vast terrains or obstructed configurations.
