With mobile alerts, a built-in buzzer, Flood and Rain Detection modes, IP44 protection, and battery-powered flexibility, it gives you a simple way to monitor high-risk areas and act quickly when leaks happen.

SmartSensor provides comfort to you and your family in the rooms that matter most while saving you energy and money. Through infrared technology, SmartSensor detects when a room is occupied and communicates that information wirelessly to your smart thermostat from up to a range of 60 feet prompting automatic temperature adjustments for comfort.
