Zooz 800LR Z-Wave Long Range Water Leak Sensor ZSE42 800LR – Indoor Leak Monitoring (Hub Required)

Smart leak protection you can rely on

Meet the Zooz 800LR Leak Sensor, a compact indoor Z-Wave device designed to help you catch moisture before it becomes a problem. When paired with a compatible hub, it sends alerts to your phone the moment it senses water, giving you time to respond and protect floors, appliances, and valuables. Used as part of a broader flood-prevention setup, it can coordinate with other devices to support proactive prevention, even when you’re away from home.

Smart placement and durable design

Thanks to its extra-small footprint, you can tuck the sensor beneath dishwashers, behind laundry machines, near sump areas, or in utility closets without drawing attention. The latest unit features a fully sealed battery cover and an IP66 rating, resisting dust and water exposure in busy indoor environments while staying discreet.

Performance you may notice

The 800 series chip delivers stronger range and longer battery life, which can translate into quicker and more reliable alerts when a leak is detected. If your hub supports Z-Wave Long Range, you may enjoy ultra-stable direct communication between devices, reducing the chance of missed updates.

Important notes and scenarios

Indoor-only installation; requires a Z-Wave hub to receive readings. It’s designed to detect moisture and alert you accordingly, not as a standalone alarm system. The device ships with a CR2450 battery installed and operates within typical indoor temperature ranges. If you’re unsure about hub compatibility, please contact the seller or Zooz support before purchasing.

For a complete flood-prevention workflow, you can pair the 800LR with the Zooz Titan Water Valve actuator to automate shutoff when a leak is detected, creating a proactive defense against water damage.

What you should know about setup and usage

The sensor is best used in conjunction with a Z-Wave hub (sold separately) that supports the software you rely on. Smart speakers can display readings only when connected through a compatible hub, so plan your setup accordingly to receive mobile alerts and automation triggers.
