Sleep Sensing FAQ

Sleep Sensing on the second-gen Nest Hub helps you sleep better. It tracks your sleep and detects your breathing and disturbances, like coughing or snoring. And it gives you personalized insights with tips to improve your sleep. So you wake up well rested and refreshed, and stay energized throughout the day.

Nest Hub (2nd gen)’s Motion Sense feature uses low-power radar to detect movement and breathing. Once your Nest Hub determines that you're in bed, it will track your sleep information, breathing, the time of day, and the light and temperature in the room. If you turn on sound event tracking, Nest Hub will use its microphones to detect sound events (like when you cough or snore) during sleep tracking. Sleep tracking still works if you don’t turn on sound event tracking.

When you purchase Nest Hub (2nd gen), it will include a preview of Sleep Sensing. You can use it until next year with no additional cost.

Nest Hub (2nd gen)’s Sleep Sensing feature is only able to track a single person’s sleep and does not currently support multiple users.

The Sleep Calibration step on your Nest Hub (2nd gen) helps detect how far away you are when you’re sleeping. During sleep tracking, Nest Hub pays attention to anything within the range it set during calibration. When you calibrate your device, make sure that you’re the only person in the room, and your pets aren’t around. That way, your Nest Hub (2nd gen) can better differentiate between you and other people or pets based on your proximity to it.

It’s important to know that the Sleep Sensing algorithm doesn’t identify you uniquely, so if another person or even a pet sleeps in the same spot or between you and your Nest Hub, this will affect your data.

Your Nest Hub (2nd gen) uses Motion Sense’s low-power radar to detect movement and breathing. No distinguishable images of your body or face are generated or used for Sleep Sensing with Motion Sense.
