Description

Create the ideal room temperature. The Smart Temperature and Humidity Room Sensor works only with the CYNC Smart Thermostat (sold separately) and measures temperature and humidity in real time. Set a schedule in the CYNC app and change your bedroom temperature from cool at bedtime to warm at sunrise. Add sensors to different rooms and create the preferred temperature in the rooms you are in during different times of day. Eliminate cold and hot spots in your home by making the temperature more consistent throughout the house.
