This Smart Leak Detector can be placed anywhere in your home where water leaks and moisture could pose a hazard. The water leak detector can identify problems caused by environmental factors or fixture malfunctions, in places such as the basement or laundry room, to provide 24/7 protection. When water, excess humidity, or extreme temperatures are detected, the water leak sensor sends an alert via the Moen Smart Water Network App, sounds an audible alarm, or emits a blinking LED light. Combine the Smart Leak Detector with the Flo Smart Water Monitor and Shutoff for whole-home protection. Review: Decent - updated - This alarm works perfectly at detecting water. A few caveats: As people mentioned, the pairing and Wi-Fi setup steps are missing from provided setup instructions, however, within minutes I located a short YouTube video that quickly filled in the blanks, and once you do this, it takes a few minutes to connect. Second caveat is that the provided alarm is very quiet. Your smartphone has louder ring options. So, you really need to rely upon the iPhone notification alerts to have a clue that it is going off, unless you are sleeping right next to your sump pump or wherever. I rigged mine to hang into a basement drain with the sensor on cord. Works. My sump failed, and I would never have known since I don’t go into basement daily and check, and dehumidifier regularly drains to this pump. I got a notification on iPhone from the Flo app while away from home, and checked sump upon return to determine sump had failed, but water was still in drain, so no overflow. I caught it early enough to minimize cleanup. It’s just a little, relatively cheap device, but it works. Review: Don't buy this until they work out the software kinks - This is a rare negative review for me since I tend to just move on if the product doesn't work for me. I returned this and bought another product (X-sense) that was much less expensive and installed instantly and just plain works. CONS: -These were expensive at almost $55 each (I purchased two) -I could never get both of them to install and show in the app. (I'm a heavy and long-time user of smart devices so, in theory, I should have been able to get them to work) -One of the 3 volt batteries arrived with only a 58% charge (the other was close to 100%). I looked up replacements costs for a CR123A lithium and they cost between $2 and $7USD each. Pretty expensive for something that gets replaced every other year. Plus you're probably not going to have too many of these spares around the house. -The app wasn't intuitive and had some strange quirks at almost every turn. Even after I deleted my device on the app, then deleted the app, I still got a text saying there had been no communication with the device. This stems from the fact the information is moved into the cloud and you can see it with a browser online. The online software has no ability to configure anything (that i could figure out) so I expect to be seeing this message for a long time. PROS: -Moen products are usually pretty decent in my experience -It looks great so good job you design folks! -The feature of having a small sensor on a cable from the main part was one of the selling features for me. It allowed me to place the sensor under our narrow washer height and also move it around and retrieve it. -Leak detection worked but by the time I was able to test it, I was already done mentally ## Features - PROTECT YOUR HOME: Place in areas at risk for water damage like basements, washing machines, or water heaters to help detect leaks before costly damage occurs - 24/7 LEAK DETECTION: Smart monitoring technology continuously detects moisture to help reduce the risk of water damage with reliable, always-on performance - REAL-TIME ALERTS: Receive instant notifications through the Moen Smart Water Network App when leaks are detected, helping you act quickly wherever you are - WHOLE-HOME COVERAGE: Connect multiple detectors for expanded protection throughout your home; available in single units or convenient multi-packs - WI-FI CONNECTIVITY: Requires a 2.4 GHz Wi-Fi network to enable app connectivity, smart alerts, and seamless integration into your connected home - VERSATILE USE + RELIABLE PERFORMANCE: Use as a standalone monitoring device or pair with the Moen Flo Shutoff (sold separately); enhanced structural support keeps the battery securely in place for consistent operation - SMART HOME INTEGRATION: Compatible with the Moen Smart Water Network to help create a more connected, proactive home water management system ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0855BFQCZ | | Audible Noise | 51 db | | Battery Description | Lithium | | Best Sellers Rank | #10,053 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #13 in Water Detectors & Alarms | | Brand | Moen | | Built-In Media | battery, remote sensing disc with 48" extension cable, self-adhesive wall mount sticker, smart water detector, wall mount base, wall mount screw | | Color | White | | Compatible Devices | Washing Machine | | Control Method | App | | Customer Reviews | 3.4 out of 5 stars 1,326 Reviews | | Item Dimensions L x W x H | 2.64"L x 1.5"W x 3.25"H | | Item Type Name | Smart Water Leak Detector, 1-Pack | | Item Weight | 4.48 ounces | | Manufacturer | Moen Incorporated | | Manufacturer Warranty Description | 1 Year Warranty | | Maximum Range | 48 inches | | Mfr Part Number | 920-004 | | Model Number | 920-004 | | Mounting Type | Tabletop Mount | | Number of Batteries | 1 CR123A batteries required.
