Smart thermostats can provide insights into sleep quality, allowing researchers to infer a person’s sleep patterns without invasive monitoring. The finding is one of several developments presented this week at Sleep 2024, the annual meeting of the Associated Professional Sleep Societies.

Researchers analyzed eight terabytes of data collected from Ecobee smart thermostats in more than 178,000 households. Homeowners voluntarily contributed this data for energy efficiency research. The study team — led by postdoctoral researcher Jasleen Kaur — leveraged the Ecobee motion sensors to accurately identify complex sleep patterns and disturbances.
