Review: Works Great – My Pipes Can’t Hide Anymore - This little sensor is like the undercover detective of smart home gear—quiet, tiny, and extremely good at its job. The Zooz ZSE42 800LR caught a leak under my sink faster than I catch typos after I hit send. Setup was a breeze with my Z-Wave hub, and the long-range signal didn’t break a sweat reaching across the house. It just sits there patiently, waiting for a drop of drama—and when it happens, boom, instant alert. If you want peace of mind in a tiny, efficient package, this sensor is the way to go. Honestly, it works so well I’m tempted to hide one in the fridge just to catch suspicious drips.
Review: TRASH PRODUCT - Couldn't even stay connected for 5 months to home assistant before randomly failing. I found out it randomly failed after my laundry room flooded with 2 inches of water. Trash product, Trash company. This is such a bad failure nothing customer service could ever do would make up for the cartoonish failure of this trash product.

## Features

- PREVENT WATER DAMAGE: Receive alerts on your phone when water is detected by the sensor once you include it to your Z-Wave hub (required, sold separately). Check below for compatibility. Pair with the Zooz Titan Water Valve actuator (sold separately) for a smart flood prevention system.
- EXTRA SMALL: Place it under your appliances to monitor for leaks discreetly. NEW design with fully sealed battery cover and IP66 rating.
- NEW 800 SERIES CHIP: You get more Z-Wave range and longer battery life with this upgraded sensor. Better signal means more reliable and quicker reports to help you act faster in case of a leak. It's also Z-Wave Long Range ready so if your hub supports this feature, you'll enjoy ultra stable direct communication between devices.
- Z-WAVE COMPATIBILITY: Supported by open Z-Wave systems only, including Home Assistant, HomeSeer, Hubitat, and Ezlo hubs (NOT supported by older Vera hubs). Works best with the Z-Box Hub. Compatible with SmartThings. NOT supported by alarm panels like Ring Alarm, Vivint, Qolsys, 2GIG, ADT, or others.

### ⭐⭐⭐⭐⭐ Works Great – My Pipes Can’t Hide Anymore
*by D***T on October 21, 2025*

This little sensor is like the undercover detective of smart home gear—quiet, tiny, and extremely good at its job.

### ⭐ TRASH PRODUCT
*by J***I on June 14, 2023*

Couldn't even stay connected for 5 months to home assistant before randomly failing. I found out it randomly failed after my laundry room flooded with 2 inches of water. Trash product, Trash company. This is such a bad failure nothing customer service could ever do would make up for the cartoonish failure of this trash product.

### ⭐⭐⭐⭐⭐ Small footprint & sensors right on floor
*by J***M on August 3, 2023*

Bought 15 & all were included successfully into Home Assistant and working fine after a few days. I like that these leak sensors touch the floor since I want to find leaks ASAP. Yes, the sensor might get damaged by water over about 1/8" deep, but I'll get notified way before the water gets that high. I'm fine with losing a $30 sensor to save hundreds or thousands. Some sensors I looked at won't sense water until the water is 1/8" or more. Too late in many cases. They have a very small footprint & easily hide behind toilets & under sinks. They seem to wakeup every 6-12 hours to update the battery status back to controller. So far, so good. If I have issues, I'll update this info.
