As of the last update this was added to the watch, but there was a note stating that it had not been enabled in Garmin connect. Several months down the track and still not available, any idea when it might be implemented?
In my experience the REM sleep is not very accurate. Three mornings in a row I awoke and lay in bed looking at my phone. All three times that was recorded as REM sleep even though I was most definitely awake.
