Actigraphy represents the movement recorded by the ReadiWatch and helps the system identify periods of sleep and wakefulness.
If actigraphy values are unusually high or low, the system may detect sleep incorrectly or fail to record it.
Identify the Issue
Review the actigraphy for the affected period. Signs of a possible issue include:
High activity while the user was still or asleep.
Very low or no activity while the user was moving.
Missing or incorrectly recorded sleep periods.

Example 2:
Recalibrate the ReadiWatch
If the actigraphy does not match the user’s activity, recalibrate the device by following the instructions in this article:
After completing the calibration:
Wear the watch during the next sleep period.
Sync the device.
Review the actigraphy and sleep data again.
If the issue continues, contact Support and include the affected period, the checks performed, and any relevant evidence.
