Kidde Smart Water Leak + Freeze Detector
I'm Chad, the owner of More4less. The homeowner's nightmare isn't just fire; it's water. A silent leak under a cabinet or a pipe freezing while you're away can cause thousands of dollars in damage before you even know it's happening. The pain point here is visibility: you can't be everywhere at once. I added the Kidde Water Leak + Freeze Detector to our inventory because it acts as your 24/7 sentry. It alerts your phone the second trouble starts, giving you the critical time you need to prevent a minor drip from becoming a major disaster.
- 2-in-1 Detection: Sensors for both water and freezing temps.
- Remote Mobile Alerts: Get notified instantly via the Kidde App.
- No Hub Required: Connects directly to your home Wi-Fi.

Expert Insights
"As a Home Safety Specialist, I cannot stress enough that water damage is one of the most common and costly insurance claims. The beauty of the Kidde 21031205 is its **dual-sensor technology**. It doesn't just wait for water to touch it; it actively monitors ambient temperature to warn you *before* a pipe bursts from freezing. Smart sensors like this are no longer a luxury gadget; they are a fundamental part of modern home maintenance, acting as an early warning system for the infrastructure of your home that is often out of sight, out of mind."
Protection That Travels With You
Unlike standard "dumb" water alarms that only beep if you're home to hear them, this smart device connects directly to your Wi-Fi. Whether you are at work, on vacation, or just in the other room, you receive a push notification the moment water or a freeze risk is detected. It's ideal for placing near "risk zones" like water heaters, washing machines, toilets, or in basements. Setup is as simple as scanning a QR code with your phone, and the compact design fits neatly into tight corners.
Simple Setup in Minutes
- Download the Kidde App and create an account.
- Scan the QR code on the back of the detector to pair it to your Wi-Fi.
- Place the unit on the floor near a potential leak source or in a cold-prone area.
- Test the unit using the test button or by placing it on a damp cloth (and get the alert on your phone!).

What Our Customers Are Saying
"Peace of mind in a little box. I put one near my sump pump and another behind the washing machine. Setup with the app was surprisingly easy, and testing it with a damp paper towel triggered the alert instantly on my phone."
"I love that this doesn't require a separate hub. The freeze detection feature is huge for our vacation home in the winter. It notified me when the temp dropped too low so I could send someone to check the furnace."
Frequently Asked Questions
Does this work if the power goes out?
The unit itself is battery-powered, so the audio alarm will still sound locally during a power outage. However, Wi-Fi mobile alerts will only be sent if your home's internet connection remains active (e.g., on a backup battery).
Do I need a paid subscription?
No, there are no subscription fees required to use the basic features of the Kidde app for mobile alerts.
