Versa 3 won't track my sleep data while on a cruise

[Peter64]

I'm on a month long cruise and my fitbit recorded my sleep for the first night but hasn't since. I assume this has to do with the rocking of the boat. How do I get my fitbit to automatically record sleep now? Should I change the sensitivity? Why is the fitbit affected by the boat rocking?

Thanks - Pete.

Hi @Peter64 - presumably you have an internet connection which will allow you to sync the watch fully with your phone.

Unless it is a tiny boat the movement shouldn't affect sleep, though noises, restlessness and increased behavioural changes in addition might affect sleep.

Even so check Why won't my Fitbit device sync?

The thing to look for in the Fitbit App is heart rate during the night to make sure it drops.

In any case try holding the watch button for 10 seconds till it blanks or vibrates and wait for the logo to appear and for it to start. This will cure any watch issues.
