See how easy it is to stay protected.
From box to full protection in a few minutes — no tools, no wiring, no professional installation.
Install
Add it to your home automation network first, then mount the unit and route the six-foot cable where leaks are most likely.
Monitor
The device continuously tracks water, freeze conditions, temperature, and humidity.
Alert
Local alarm sounds while notifications reach your phone through Matter and PuzL Cloud.
Act
Take action in minutes, not days — before a drip becomes damage.
A few drops. One second.
PuzL Detect senses as little as a few drops of water landing in the same spot on the cable, and the system responds in about one second. The cable is quick to detect fluids, easy to clean, and fast to dry.
It detects most household fluids — water, milk, juices, soft drinks, sports drinks, salad dressings, condiments, cleaners, and solvents — making it useful in pantries and around refrigerators, too. Oils are the exception.
Point detectors wait for the puddle. Cables meet the leak.
Most leak detectors use two point contacts — they only work when water happens to flow to the exact spot you placed them. The farther the puck sits from the leak, the larger the puddle must grow before detection.
PuzL's continuous sensing cable detects water at any point along its six-foot length. Wrap it around a water heater, snake it under a washer, or circle a sink trap — one cable covers multiple leak sources at once, and catches them earlier. Early detection is the key to minimizing damage.
Need more reach? Optional 25-foot extension cables are perfect for crawl spaces — where plumbing leaks often go unnoticed the longest.
From box to protected in minutes.
Plug in the cable
Insert the sensor cable into the bottom of the unit — it's a standard audio-style plug that clicks into place.
Pull the battery tab
The red light flashes to confirm the unit is awake.
Add it in your Home app
Tap “+” in the PuzL app, Apple Home, Alexa, Google Home, or SmartThings and scan the Matter QR code on the back.
Hold the button 3 seconds
When the light blinks, your app completes secure Matter authentication automatically.
Mount and route
Peel the adhesive strips, mount inside a sink cabinet or beside an appliance, and route the cable around your plumbing.

Complete control, from anywhere.
The PuzL app extends your device with controls and history your Home app doesn't show: adjust alert types, sensitivity levels, and alarm thresholds, and review day, week, month, and year charts for temperature, humidity, and leak measurements.
Built-in presets program high and low temperature and humidity alerts for specialty applications — humidors, wine cellars, music rooms, dry storage, refrigerators, and freezers. Fine-tune any threshold with sliders, or simply drag the alert lines directly on the data charts.
The app also registers your phone for PuzL Cloud notifications — so alerts reach you even when you're away from home.
