Google Nest Nest Temperature Sensor

The Nest Temperature Sensor lets you monitor the temperature in baby's room, and set your Nest Thermostat to keep it comfortable. Your heating and cooling system tries to make your whole house one temperature. The Nest Temperature Sensor lets you monitor any room you want — say, the baby's room — so your Nest Thermostat can do its heating and cooling based on that space. Just place a Nest Temperature Sensor in a room and wirelessly connect it to your Nest Thermostat E or Nest Learning Thermostat (3rd Generation) . Then you'll be able to get granular with the scheduling. Set your thermostat to keep the baby's room warm overnight, or cool the kitchen down during the hectic morning hours. It gives you more data points, so Nest can do a better job keeping you and yours comfortable. You don't have to stop at just one. You can add up to 6 sensors to each Nest Thermostat you own (with a grand total of 18 per household) and use them to refine your ability to monitor and control your Nest system.
