Your Steel HR / Steel HR Sport lets you track your sleep without requiring any action on your part. All you have to do is wear your Steel HR to sleep: it will do the rest on its own.
If you do not want to track your sleep, remove your Steel HR / Steel HR Sport before going to sleep.
Retrieving your Sleep Data
You can retrieve the sleep data collected by your Steel HR in your Timeline or on your Dashboard in the Withings App® app.
Grey: time spent awake - Medium blue: duration of light sleep - Dark blue: duration of deep sleep
The sleep stages (e.g. light and deep) are measured based on wrist movements.
The Withings App® app keeps your entire history, allowing you to easily track how your sleep data evolves over time.
Important note:
Starting with firmware version 4911, we have chosen to disable the detection of naps to focus on an improved tracking of your nights.
