It packs water, temperature, freeze and tilt into a tiny body that talks to Google Home, Alexa and SmartThings through an Arlo Security System. The Moen Smart Leak Detector still takes weather resistance, an on-device siren and an alert light on hub-free Wi-Fi. Pick the Arlo All-in-One Sensor if you already run Arlo and want tilt plus freeze; pick the Moen Smart Leak Detector if you want a waterproof local alarm without an Arlo base.
