Sleep Sensing on Google Nest Hub (2nd gen)

Sleep Sensing on the Google Nest Hub (2nd gen) can help you get a better night’s rest and improve your overall wellness. It tracks your sleep, measures your breathing and detects what could be disturbing you at night, like coughing or snoring. As Sleep Sensing gets to know your sleep patterns, you receive personalized insights and tips to improve your sleep.

Each morning on your display, you should receive a sleep summary of how well you slept the night before. You can also track your sleep history over time with the Google Fit app.

Note: Sleep Sensing isn't available on Nest Hub (1st gen).

 Sleep Sensing is not intended to diagnose, cure, mitigate, prevent, or treat any disease or condition. Consult your healthcare professional for questions about your health.

Sleep Sensing is available for preview at no additional charge through 2023. In 2024, Google plans to integrate Sleep Sensing into Fitbit Premium (currently $9.99 per month or $79.99 per year, subject to change and may vary by country). Learn more at g.co/sleepsensing/preview.

Sleep Sensing isn't currently available in all languages or countries. 

How it works

Sleep Sensing uses Motion Sense to track the sleep of the person closest to the display. Motion Sense uses a low-energy radar to detect movement and breathing. Other sensors in Nest Hub (2nd gen) detect sounds like snoring and coughing and environmental factors like light and temperature in the room.

Sleep Sensing can then determine not just when you went to bed and how long you slept but also the quality of your sleep. Once you’ve set up Sleep Sensing, all you have to do is sleep as usual in the spot you configured. There’s nothing to wear or remember to charge. You should begin to get your sleep results the next day.

The Nest Hub (2nd gen) doesn’t have a camera, so no distinguishable images of your body or face are generated or used with Sleep Sensing. Audio collected during Sleep Sensing is processed on your Nest Hub (2nd gen) only, and it isn't sent to Google. You can customize your sleep settings for additional privacy. For example, you could set or configure your Nest Hub (2nd gen) to not record sleep disturbance events like coughing and snoring.

Sleep Sensing features are subject to your permissions and settings. They use motion, sound and other device and sensor data to work and require you to place the device close to the bed and calibrate the device for your sleeping area.

If you turn on Sleep Sensing, your sleep-related data is shared with Google Assistant and should be available in the Google Fit app. Google doesn't use your sleep data for ad personalization, and you can review and delete your data any time.

Set up Sleep Sensing

What you need

Set up Sleep Sensing

  1. Open the Google Home app .
  2. Touch and hold your device's tile.
  3. At the top right, tap Settings .
  4. Tap Sleep Sensing and then Set up Sleep Sensing.
  5. To allow Sleep Sensing on your display, follow the in-app instructions.
  6. Tap Set a bedtime schedule.
  7. Choose what time you plan to regularly go to bed and wake up.
  8. Optional: The following features can be turned on to provide you with additional information to better track your sleep and give you educational sleep tips:
    • Set up sound events tracking
    • Personalized sleep suggestion 
  9. To finish setup, calibrate your sleep spot.

Calibrate your sleep spot

To use Sleep Sensing, you need to calibrate your display to recognize where you sleep.

  1.  From the bottom of your display, swipe up.
  2. Tap Settings  and then make sure Motion Sense is on.
  3. Tap Sleep Sensing and then make sure Sleep Sensing is on and then Calibrate device.
  4. Follow the on-screen instructions on your display.

Note:

  • Since Sleep Sensing monitors the spot where you usually sleep, children, pets and other family members sleeping in that spot affect your data.
  • Device placement, motion and other devices nearby might lead to inaccurate readings.
  • Sleep Sensing is designed to only show coughs and snores that come from your calibrated sleeping area. Any coughing or snoring that happens outside of your area is filtered and appears on the “Other sounds” timeline. This timeline also shows other loud noises.
  • Please make sure you inform people nearby that Sleep Sensing on your Nest Hub might process their sounds, and get their permission before you turn it on.

View sleep information

In the morning, you can get a summary of your previous night’s sleep and weekly sleep trends, and get personalized tips after about a week. You can also ask questions about your sleep patterns in general. To access this information, check the Wellness page of your display, the Google Fit app or say “Hey Google” followed by any of the sample voice commands below:

  • "How did I sleep last night?"
  • "When did I go to bed yesterday?"
  • "How much REM sleep did I get last Friday?"
  • "Tell me about my sleep stages from last night."
  • "How can I sleep better?"

Learn more about your sleep summary

Note: To have your sleep summary appear on your Nest Hub (2nd gen), you need to allow personal results and Proactive health & fitness results on your display. Web & App Activity also needs to be turned on in your Google Account. To receive answers from Google Assistant related to your sleep information, personal results and Voice Match need to be turned on.

When personal results and Proactive health & fitness results are on, anyone with access to your Nest Hub (2nd gen) can review and delete your most recent Sleep Sensing summary and wellness details.

Turn Sleep Sensing on or off

After successful setup, Sleep Sensing should automatically detect sleep when you're in your calibrated sleeping area.

When the Sleep Sensing indicator appears in the top-right corner of your display, it means Sleep Sensing is on, has detected your presence in the calibrated sleeping area, and is ready to detect sleep.

  • To pause Sleep Sensing, swipe up from the bottom of your display, then tap Sleep Sensing .
  • To unpause, tap Sleep Sensing  again and it should become active the next time you're in your calibrated sleeping area. 

Note: The Sleep Sensing indicator should also appear as active when you're near your display. It indicates Sleep Sensing is on, you're within the calibrated area, and your Nest Hub (2nd gen) is ready to detect sleep should it occur.

Deactivate Sleep Sensing and delete sleep data

You have control over how your data is used. Sleep Sensing is off by default on Nest Hub (2nd gen). Once you’ve set up Sleep Sensing, at any time you can:

Deactivate Sleep Sensing on your display

  1. Open the Google Home app .
  2. Touch and hold your device's tile.
  3. At the top right, tap Settings .
  4. Tap Sleep Sensing.
  5. Tap Deactivate Sleep Sensing and then Deactivate.

Note: When you turn off Sleep Sensing, Nest Hub (2nd gen) stops the collection of sleep data immediately. However, personalized insights and sleep summaries based on previous data might already have been sent to your display. It can take up to 4 days for these messages to expire.

How sleep data is used with Google Assistant

Assistant only stores your sleep data temporarily and uses it to give you info about your sleep, health and fitness. This data also helps troubleshoot and improve your health and fitness experience with Assistant.

Once your Assistant successfully fulfills your request to update, show, or answer questions about your sleep-related data, Google deletes your audio query. The text from your query and other Assistant usage information that's kept is used to troubleshoot, develop and improve Assistant services.
