Can you cite a medical study that evaluates the accuracy of your smart watch’s assessment of your quality of sleep?
Preferably one not sponsored by the manufacturer?

>Oura ring was 96% accurate in detecting sleep compared to polysomnography, 48% accurate in detecting wakefulness, 65% agreement in detecting “light sleep,” 51% agreement in detecting “deep sleep” and 61% agreement in detecting REM
So it's basically wrong with sleep categorization about half the time.
Seems to accurately analyze them. Conclusion "Device sleep stage assessments were inconsistent."

Great news.
Also, is there a more "layman readable" version of this paper/report?

Most devices (Fatigue Science Readiband, Fitbit Alta HR, EarlySense Live, ResMed S+, SleepScore Max) performed as well as or better than actigraphy on sleep/wake performance measures, while the Garmin devices performed worse.
