The National Home Safety Water Leak and Freeze Detector is an early warning system that notifies you on your smartphone when a leak is detected or the temperature drops below a temperature of your choice. By catching it early, you may be able to avoid expensive repairs and loss of treasured items. We are excited to introduce the Roost Smart Water and Freeze Detector, and expand our ability to offer consumers safer and smarter homes. Our unique technology delivers consumers tangible solutions that are simple to install and at affordable costs. Roost provides essential alerts and notifications that enable consumers to take faster action when it comes to home emergencies, saving the trouble and cost of repair work or major home loss. With the new Roost Smart Water and Freeze Detector, Roost now provides the ability to manage the all-too-common water leak or freezing pipes situation that we’ve all experienced in our homes at some point. Within two seconds of detecting water, the Freeze Sensor transmits an alarm notifying the user of a water leak or possible flood. The freeze detection feature also reduces the possibility of pipes freezing by transmitting an alarm notification if the temperature in the surrounding area.
