Most homes aren’t the same temperature in every room. Maybe the baby’s room gets too cold or the living room is always too warm. With the Google Nest Temperature Sensor, you can let your Google Nest thermostat know which room should be the most comfortable. It’s wireless and battery powered – just hang it on a wall or set it on a shelf. Put temperature sensors in rooms that matter most. Then you can keep the living room cool all day and warm up the baby’s room at night. Google Nest makes sure you get the right temperature, right where you want it.
