How do I enable sleep tracking on my wearable?
You must opt into and enable sleep tracking for your wearable before you can sync this data to the LE-1 app.
To be able to sync sleep data in the LE-1 app, you must turn on Sleep tracking for your wearable and opt in to it, as well as wear your wearable when you go to sleep.
Confirm that you have enabled sleep tracking with your wearable device within either the Apple Health (external article) or Google Health (external article) app.
If you don't wear one to sleep or you haven't enabled sleep tracking, you may see "No Data" listed here.
