One Sporadically Does Not Record Sleep

[mitch5252]

I have had my One for several years now and know how to use the sleep function.

The problem is that it will sporadically NOT log the sleep record. 

I specifically wait for vibration, both at night and in the morning.

Not logging happens maybe once a week or so - been working fine for at least 5 or 6 nights, but no sleep recorded this morning. I synced just now for the 2nd time today and still no sleep. 

Any suggestions?

Where do you wear your One when you go to sleep? Does it matter? I know the wrist one they ask you to put it on your non-dominant hand.

I wear it on my non-dominant wrist. Just started happening 2 nights ago (happened again this morning - no sleep registered). But I just now did a reset of the One. Hopefully, that will fix the problem.

Obviously your One is a wristband. Mine is not. It only clips. Do you know if the clip on ones will also track sleep?

The One is designed to be a clip-on. 

When purchased, the box contains a sleep wristband.

I recently replaced the sadly worn out wristand with a workout sweat wristband. Cut a little slit in it and popped the One inside. Works great and is actually more comfortable than original that came with One.
