Sleep Score not picked up by Training Readiness

I've been using my Index Sleep Monitor for a few nights now and it records my sleep as expected and I get a sleep score.  However, in the Training Readiness section of the Garmin Connect App, it has a blank sleep score and says - No data on device.

So my training readiness is not taking my sleep into account which seems like the reason to use this device in the first place.

  • In another thread I picked up that you first have the Index Sleep sync for two minutes, and only after that you can put on and sync your watch. Did that this moring and I got stress data back.

  • It was a one-off. Synced my index sleep before putting on my watch, no stress data. It really sucks as it throws off averages for the entire day.

  • Just had this problem for the first time.

    The only difference was that today the sync with the watch was during the sleep window.

    Took off the band, sync it. Put the watch off sleep and sync it.

  • I wish to report that my ISM was late to sync (though as I wake up everyday, i manual sync them), here's timeline

    - my sleep period is from 23:30 to 5:30 daily

    - wake up at 5:30 and start sync my ISM via GC, the sleep score appears approx.. 5 minutes later (05:35)

    - however, when I check the "device" ISM from GC, it shows "Sync today at 06:03" 

    Why there's delay in sync ?  I believe the training readiness appears after 06:03, as 05:35, I could not see training readiness data yet.


    I hope development team could help to expedite the sync and have the training readiness data shown especially for morning runners.

  • Maybe that is what is happening.watch sync before true server ISM sync

    Just checked my ISM sync time it says 6:11 however it was at 6:00

    Since my watch was at my bed table I'm sure tthat the watch sync was before 6:11.

  • Most likely the delay was from the GC's server... by the way, did you get your training readiness ay 6:00 ?  Or later at 6:11? 

  • The trainings readiness, today, doesn't have sleep score or stress score.

    So my thought is that you need to have those values on Garmin server's before watch sync.

    In fact, my stress value, right now is at 87 at the watch and 14 at connect.

    All the sleep data was lost in the calculations, however, the sleep watch widget is correct.

    It seems that the watch only does a one time, stress, training readiness calculation and if it doesn't have the data in the servers it never catches up.

  • Do you wear both watch and ISM during sleep? 

    I sleep without wearing watch, just ISM.  Anyway I was told ISM would take priority on sleep score if you wear both, correct me if i am wrong.

  • I actually bought the ISM to get rid of the watch during sleep. If the watch is a requirement, the ISM is going back under the "False advertisement" regulations, as commercials truly showed people sleeping without watch and all data nicely being synced.

  • I saw this post and was hesitant to order it since I too dont like sleeping with watch. I've been using it now for a week and I have not noticed anything missing. I have 30 days to verify and return it if not working as advertized but till now all seems ok! I have FR970 btw if it makes difference!
