How to monitor sleep for daytime sleepers?

For people whose main sleep occurs during the day, the sleep plan can be adjusted to the daytime period when sleep occurs, and the device will recognize sleep based on the sleep plan of the day. If no setting is made, the device will still recognize this period of sleep as a sporadic nap.

How to set up the sleep plan: Open the Zepp App > Sleep > Sleep Regularity > Sleep Plan to set it up.
