Fitbit Sleep Summary

Sensor parameters description for [FITBIT_SLEEP_SUMMARY]:

Key                              Description
[TABLE] Database table name or file path where the sleep summary data is stored. Source data type and column format are defined in Device Data Source Configuration.

Column format could be JSON or PLAIN_TEXT. Data with JSON column format is obtained from Fitbit API directly. Summary data and intraday data come together in JSON format. Each row doesn’t have to contain the data for a single day as it depends on the way Fitbit API is queried. Examples of the source data with two formats are as follows. Data with JSON format is chunked.

Parameters description for [FITBIT_SLEEP_SUMMARY][PROVIDERS][RAPIDS]:

Key                              Description
[COMPUTE] Set to True to extract FITBIT_SLEEP_SUMMARY features from the RAPIDS provider
[SLEEP_TYPES] Types of sleep to be included in the feature extraction computation. Fitbit provides 3 types of sleep: main, nap, all.
[FEATURES] Features to be computed from sleep summary data, see table below

Features description for [FITBIT_SLEEP_SUMMARY][PROVIDERS][RAPIDS]:

Feature Units Description
countepisodeTYPE episodes Number of sleep episodes for a certain sleep type during a day segment.
avgefficiencyTYPE scores Average sleep efficiency for a certain sleep type during a day segment.
sumdurationafterwakeupTYPE minutes Total duration the user stayed in bed after waking up for a certain sleep type during a day segment.
sumdurationasleepTYPE minutes Total sleep duration for a certain sleep type during a day segment.
sumdurationawakeTYPE minutes Total duration the user stayed awake but still in bed for a certain sleep type during a day segment.
sumdurationtofallasleepTYPE minutes Total duration the user spent to fall asleep for a certain sleep type during a day segment.
sumdurationinbedTYPE minutes Total duration the user stayed in bed (sumdurationtofallasleep + sumdurationawake + sumdurationasleep + sumdurationafterwakeup) for a certain sleep type during a day segment.
avgdurationafterwakeupTYPE minutes Average duration the user stayed in bed after waking up for a certain sleep type during a day segment.
avgdurationasleepTYPE minutes Average sleep duration for a certain sleep type during a day segment.
avgdurationawakeTYPE minutes Average duration the user stayed awake but still in bed for a certain sleep type during a day segment.
avgdurationtofallasleepTYPE minutes Average duration the user spent to fall asleep for a certain sleep type during a day segment.
avgdurationinbedTYPE minutes Average duration the user stayed in bed (sumdurationtofallasleep + sumdurationawake + sumdurationasleep + sumdurationafterwakeup) for a certain sleep type during a day segment.

Assumptions/Observations

  1. There are three sleep types (TYPE): main, nap, all. The all type contains both main sleep and naps.

  2. There are two versions of Fitbit’s sleep API (version 1 and version 1.2), and each provides raw sleep data in a different format:

    • Count & duration summaries. v1 contains count_awake, duration_awake, count_awakenings, count_restless, and duration_restless fields for every sleep record but v1.2 does not.

  3. API columns. Features are computed based on the values provided by Fitbit’s API: efficiency, minutes_after_wakeup, minutes_asleep, minutes_awake, minutes_to_fall_asleep, minutes_in_bed, is_main_sleep and type.
