Hello @han88fia
It seems to work really well for some people and be more hit and miss for others. In my case, I get sleep scores and stages more than 90% of the time (I just checked and in 6 weeks I had one night that didn't record them). This is my experience and what works for me. It might not work for everybody though.
I wear my Charge 5 on my non-dominant wrist. I wear it on that side all the time but have heard it might help people having problems getting scores to switch to the other wrist at night.
Sleep sensitivity is set to Normal. If you have your sensitivity switched to sensitive it picks up small movements as being awake and doesn't always record your sleep.
I don't do anything or press anything or even sync before I go to bed. I just go and let the Fitbit do its own thing. In the morning I sync when I wake up. Problems start to occur when people start sleep from the App. You don't need to do that with the devices that measure heart rate.
That's what seems to work for me.
I hope that helps you a bit.
