About this item

Product details

The Kidde HomeSafe Smart Water Leak Detector & Freeze Alarm keeps watch over two common household concerns at once: water leaks and significant temperature drops. When it senses either condition, it sounds an audible alarm and sends a notification to your smartphone through the Kidde app, so you can check in on the detector through Kidde HomeSafe even when you are away from home. Because it is designed for indoor use in the spots where water trouble and cold conditions tend to begin, you can place it under sinks, near pipes and toilets, or around refrigerators, dishwashers, washing machines, and water heaters, as well as in tight areas like crawl spaces and basements. Setup is straightforward out of the box, and the compact design makes it easy to add monitoring in more corners of your home.

  • Wi-Fi enabled to send alerts through the Kidde app and Kidde HomeSafe, so you can check on the detector while away.

I purchased the Kidde Battery Operated Smart Water Leak Detector after dealing with a serious flooding issue, and it has been exactly what I needed. Setup was quick and straightforward, and the detector provides some much-needed peace of mind when I'm away from the property. It's compact, easy to place near plumbing or other areas where a leak could occur, and the alarm is loud enough to get your attention. For something designed to potentially prevent thousands of dollars in water damage, it's an inexpensive layer of protection. After learning the hard way that water has absolutely no respect for business hours, weekends, property managers, or personal belongings, I'd rather have several of these around than discover another leak after the damage is already done. Highly recommended for apartments, offices, bathrooms, kitchens, water heaters, and anywhere else an unnoticed leak could become a very expensive problem.

Minor Setup Problem I had

I'm an retired electronics technician and had hard time working with my phone's ability to read the QR codes. However, when it worked, it just about set itself up with no additional programming. A great feature is that it sends the alarm signal to the app on your cellphone so you are notified even if your not home. Note: When testing it out with water, I did it outside since the alarm has a ear piercing volume, and I have cats in my home.

Maybe it works.

The item's original packaging looked shop-worn like it had been sitting around somewhere in strong sunlight. However, it was sealed and its enclosed AA batteries were in their original packaging and worked. The unit was bothersome to connect to my cell phone, It tests OK when tried in a test puddle of water so I hope it will alert me if my HWH starts leaking.
