$68.00

Buy on Amazon USA

The Resideo L1 WiFi Water Leak and Freeze Detector takes the verdict on a 2-year warranty, IP44 weather sealing and broader connectivity, which is enough to recommend it as the default water leak sensor of the two. The Arlo All-in-One Sensor answers with the more affordable price, the stronger owner reviews and broader smart home integrations. Buy the Resideo L1 WiFi Water Leak and Freeze Detector as a dedicated water leak sensor with a siren, a light and a sensing cable; buy the Arlo All-in-One Sensor only inside an existing Arlo system, where tilt and voice assistants come along for the ride.
