Frequently Asked Questions

What is the biggest difference between the Kidde WiFi Water Leak & Freeze Detector and the X-Sense Wi-Fi Water Leak Detector?

Warranty and sealing versus smart-home breadth. The X-Sense Wi-Fi Water Leak Detector is IP66 with a 5-year warranty and a 110 dB alarm, but it has no Alexa, Google Home or HomeKit and pairs with a separate base station. The Kidde WiFi Water Leak & Freeze Detector is hub-free Wi-Fi with freeze sensing and those voice platforms.

Buyers who want an IP66 puck with a 5-year warranty, a 3-year battery, and a very loud local alarm, and who do not need freeze detection or Alexa or Google Home.

Who should buy the Kidde WiFi Water Leak & Freeze Detector?
