Product Information
Sonoff Zigbee Water Leak Sensor (SNZB-05P)
Place this sensor on the floor near a water heater, washing machine, sink, or AC unit, and it will alert you instantly if it detects a water leak — even a small one (as little as 0.5mm). It uses Zigbee (a wireless smart home protocol that connects devices through a hub), so it works through a hub and stays connected even if your internet goes down.
A small device that can save you from expensive water damage.
Key Features:
- Detects Tiny Leaks: Triggers an alert for water as shallow as 0.5mm.
- 5+ Year Battery: Long-lasting battery — set it and forget it.
- Extend Detection Area: Add water detection cables to cover larger areas.
- Works Offline: Zigbee-based — alerts work even without internet.
- Smart Automations: Pair with a smart water valve to automatically shut off the water supply when a leak is detected.
- Loud Buzzer: Built-in alarm sounds when water is detected.
💡 Pro Tip: Place one behind your washing machine and another under your water heater. Pair with a smart water valve — if a leak is detected, the water shuts off automatically before any damage is done.
