【Leak & Drip Detection】The elevated probe design detects liquid levels as low as 0.5mm and works reliably on metal surfaces without false triggers. Its concave water collection design quickly senses drips and stops leaks at the source. 【Extended Detection Capability】Supports connection with water leak detection cables (sold separately or as part of sensor kits). Whether covering a wide area or a narrow spot, water leaks are detected accurately. Extension cables can be connected in series without length limitation. 【Real-time Alerts & Multiple Notifications】Working as a home water leak detector, SNZB-05P will instantly push app notifications to alert you once water is detected, and Zigbee local control scenes can trigger gateway alarms even during WiFi outages. 【Zigbee 3.0 Compatible】Compatible with Zigbee 3.0 hubs such as SONOFF NSPanel Pro, SONOFF iHost, ZB Bridge variants (ZB Bridge, ZB Bridge-P, ZB Bridge-U), and SmartThings Hub V3. 【Home Assistant Support】Easily integrates with Home Assistant via ZHA or Zigbee2MQTT (requires Zigbee dongle like SONOFF ZBDongle-P or ZBDongle-E) for seamless home automation.
