Houses of the Soli

Sleep Sensing uses Google’s purpose-built Soli chip, a low-energy radar that detects motion rather than faces

Every breath you take

On a bedside table, the Hub analyses movement and breathing to track sleep quality. It picks up snoring and coughing episodes, as well as temperature and light changes that might identify why you’re waking up groggy.

Every bond you break

Sleep Sensing is an opt-in feature and Google says audio recordings, such as snoring, are not uploaded anywhere. It also says data isn’t used to personalise ads, so you shouldn’t be seeing Nytol pop up after a particularly rough one.

Every move you make

It takes 24 hours to start building up a picture, then offers suggestions on how to improve your sleep. You can also access your data through the Google Fit app, and there’s a suggestion it could work with Fitbit devices in the future.

We’ll be charging you

None of this is much use if you like to have your smart home controls in the living room, of course. Google has also suggested that this feature is on preview until 2022, which means it may well cost extra once out of beta.
