We knew it was on the way, and now it’s here: Google Assistant support has started rolling out to the Fitbit Sense and Fitbit Versa 3 smartwatches, with sleep logging one of the features that’s already been integrated.
Once the software update is installed, you can lift your Fitbit Sense or Fitbit Versa 3 wearable and ask “how did I sleep last night?” or say “show my sleep summary” to get at your stats, as 9to5Mac reports.
