Missing sleep data

I keep having half of night missing. At least once a week, sometimes twice a week there is no HR or breathing data recorded half the night, as a result sleep data inaccurate, as there was no tracking at all.

Are you wearing your watch too loose? Do you sleep with lots of movement so it might happen that your watch gets somehow moved in way it can't measure your HR?

Good question. It is not super tight, otherwise it is uncomfortable. Any suggestions how tight it should be for the best tracking

It should be tight enough so that you do not see the optical HR lights in the dark.

My Vivomove Luxe randomily turns HR scanning etc. to "activity mode", therefore sometimes it scan only half of the night, sometimes it doesn't scan during night at all and sleep statistics are missing. Definitely a bugged software.

I heard elsewhere (not confirmed) that the watch will only track a 4 hour period to save batteries. Can you check to see if your sleep data is exactly 4 hours? That would suggest it's not a fit issue but a feature/bug.

4hrs is, afaik, only the oxy tracking. Sleep data itself should be tracked all night long.
