Kidde WiFi Water Leak & Freeze Detector vs YoLink Water Leak Sensor 1

The YoLink Water Leak Sensor 1 wins overall on price, reviews, warranty, weather sealing, and an alert light. The Kidde WiFi Water Leak & Freeze Detector remains the better no-hub pick when freeze alerts and Alexa or Google Home matter more than LoRa range.

How they connect. The Kidde WiFi Water Leak & Freeze Detector joins 2.4 GHz Wi-Fi on its own. The YoLink Water Leak Sensor 1 uses LoRa through a YoLink hub sold separately, which is what gives it long-range coverage and a 5-year battery, at the cost of that extra hardware.

Only the Kidde WiFi Water Leak & Freeze Detector does. It tracks temperature and raises freeze alerts at 37 °F or on a rapid drop. The YoLink Water Leak Sensor 1 is water-leak only, with no temperature sensing.

The Kidde WiFi Water Leak & Freeze Detector has an on-device alert sound. The YoLink Water Leak Sensor 1 is silent on the puck and uses an alert light instead, so an audible local alarm means adding a YoLink siren or SpeakerHub.

Buyers who already run a YoLink hub, need LoRa reach into basements, attics or outbuildings, and want an IP68 puck with a 2-year warranty and a 5-year battery.

Buyers who want a hub-free Wi-Fi leak puck with freeze alerts, an on-device siren, and Alexa, Google Home or Home Assistant, without joining the YoLink ecosystem.
