Wrong sleep tracking and no SpO2

Hi all,

I have a brand new Epix 2 (worn since a week ago).

This morning I noticed that, for the first time, the watch didn't track the sleep as well as the previous nights. For instance, it tracked I felt asleep (light and REM sleep) after 6:50, while I was actually awake in my bed, reading news. Also, it didn't track SpO2 overnight (it never happened in the first and past 7 nights).

The watch was worn as usual.

Do you have any idea on why I had this issue? Thanks.

    Oh yes, i have tried to change the scheduled sleep period, over a few days. I did not see any impact at all. I tried to move it out hoping that falling asleep before 11pm would be improbable, but no. No impact at all. The scheduled sleep period is just a power mode.

    That power mode observation gave me the idea that sleep should be treated like an activity. It could be included in MoveIQ option for those users for whom the auto detection works fine, and others could start a sleep activity whenever they know they are going to sleep.

    Got it...i need to test what happens if i change my sleep schedule and i put the starting time at midnight or even later.

    If it starts to record the sleep only at 10/11 when i go to sleep earlier, it means that your watch is "defective" and i would ask for a replacement to be honest.

    Regarding the HR graph, it was around the beginning of sleep as the problem is there and not at the end Smiley

    Getting worse guys! Last night and the night before it recorded very long awake times: fact is I was sound asleep when the watch recorded I was hopping around. I checked the heart rate and for 2 very long stretches the heart rate was not recorded. now these 2 intervals were not precisely correspondent with the "fake awake", but very close to those intervals.

    Should I complain with Garmin and ask for a replacement?

    Any chance that the contact of the watch was poor because of your sleeping position? I had a couple of times some gaps in HR recordings and, for SPO2, a handful of times.

    Hard to say. I don't think that my sleeping position has changed significantly, though. At least I don't see a reason why.....

    But I can confirm that, when the watch doesn't record my heartbeat, it presumes I'm awake; I checked the sleep stages graph with the heart rate graph and it appears very clearly. It could be a default software setup (no heart rate=no sleep), but it is, however, a very questionable performance. I wonder what would happen if I sleep with the Polar H10 on....

    OHR has to be active to provide sleep tracking (so if using battery saver linked to sleep profile you have to go into battery saver and edit it so that it allows OHR).

    If you are getting periods of sleep tracking and periods where it doesn't, and you have no HR during that periods, that is the cause - the lack of HR. The big questions is why there is no HR for those periods. Perhaps you are wearing your watch too loosely?

    I swop wrists when I go to bed (i.e. move the watch from my left wrist to the right wrist) - to give my normal wrist a chance to breathe etc; also cause I tighten the strap a little bit more than when I usually use it, i.e. how I would have it for an activity.

    Bottom of strap is at least 2 finger widths from base of palm (helps OHR to sit between wrist bones); and tighten it enough so that it can't slip. Can't get a finger fully between wrist and OHR, but can lift the watch just off my skin (whereas when swimming tighten it so can't even do that to prevent water between skin and OHR).

    As much as i was a strong believer in the sleep schedule, i must admit that setting the starting time doesn't really affect the sleep tracking.

    During the last week, i set a starting time of the sleep schedule at 3am and the watch, correctly, started the tracking around 10pm.

    On the opposite side, i already tested(could be wrong again of course :D) that wakening up only for few minutes(5-10 let's say) near the end of the schedule, or outside of the schedule, stops easily the tracking. For this reason my sleep schedule ends at 10am also if i wake up a lot earlier.

    Ending the sleep, manually, with the activity button works flawlessly and it's not a big deal.
