💧 Water Leak Detection
⚡ Key Features

- Daisy-Chainable — connect multiple WLDC200 cables in series with no maximum total length — cover an entire room, basement, or commercial floor
- Wide-Area & Narrow-Space Detection — flexible cable runs along walls, under appliances, around pipes, or through narrow gaps where the sensor alone can't reach
- Gold-Plated Contacts — corrosion-resistant connectors for long-term reliability in humid environments
- Plug-In Connection — connects directly to the SNZB-05P sensor via a simple plug — no tools or wiring required
- Designed for SNZB-05P — purpose-built accessory for the SONOFF SNZB-05P Zigbee water leak sensor
🏠 Where to Run the Cable
Along Pipe Runs
Run the cable along exposed pipes under sinks, behind toilets, or along geyser overflow pipes. Detects leaks at any joint or connection point.
Behind Appliances
Loop behind washing machines, dishwashers, or fridges with water connections. Catches hose leaks and overflow before they spread.
Basement Perimeter
Daisy-chain multiple cables around the full perimeter of a basement or server room. First alert for rising water or wall seepage.
Under Geyser / Water Heater
Place the cable under your geyser or hot water cylinder. Detects slow drips from the pressure relief valve or tank failure.
