Unlike a remote sensing disc, this model sits directly at the point you want to watch. Kidde specifies an indoor, clean, dry, level surface and cautions against metallic surfaces. Choose an accessible low point where water could reach the detector, while following the instructions about obstruction and rising water.
Two AA batteries are included. Remote app notifications use 2.4 GHz Wi-Fi, and no additional hub is required. A convenient physical location still needs a suitable connection; phone notifications depend on the home network and do not replace checking the detector and maintaining its batteries.
The model reports water and low-temperature conditions, with rapid temperature-change notification described in its data sheet. It does not physically close a valve. Compare it with Moen when the placement method matters: Kidde needs room for the body, while Moen’s included remote disc can extend the sensing point.
