An effortless way
to track your sleep.
Sleep Sensing1 uses motion and sound to monitor your sleep – so there’s nothing to wear or remember to charge. It tracks when you go to bed, when you wake up, and how long you’ve slept.2

Every morning, you can see your sleep summary on Nest Hub. Or just ask, “Hey Google, how did I sleep last night?”
