Fitbit Steps Intraday

Sensor parameters description for [FITBIT_STEPS_INTRADAY]:

Key	Description
[CONTAINER]	Container where your steps intraday data is stored, depending on the data stream you are using this can be a database table, a CSV file, etc.
[EXCLUDE_SLEEP]	Step data will be excluded if it was logged during sleep periods when at least one [EXCLUDE] flag is set to True. Sleep can be delimited by (1) a fixed period that repeats on every day if [TIME_BASED][EXCLUDE] is True or (2) by Fitbit summary sleep episodes if [FITBIT_BASED][EXCLUDE] is True. If both are True (3), we use all Fitbit sleep episodes as well as the time-based episodes that do not overlap with any Fitbit episodes. If [TIME_BASED][EXCLUDE] is True, make sure Fitbit sleep summary container points to a valid table or file.

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

Key	Description
[COMPUTE]	Set to True to extract FITBIT_STEPS_INTRADAY features from the RAPIDS provider
[FEATURES]	Features to be computed from steps intraday data, see table below
[REFERENCE_HOUR]	The reference point from which firststeptime or laststeptime is to be computed, default is midnight
[THRESHOLD_ACTIVE_BOUT]	Every minute with Fitbit steps data wil be labelled as sedentary if its step count is below this threshold, otherwise, active.
[INCLUDE_ZERO_STEP_ROWS]	Whether or not to include time segments with a 0 step count during the whole day.

!!! note "Assumptions/Observations"

1. _Active and sedentary bouts_. If the step count per minute is smaller than `THRESHOLD_ACTIVE_BOUT` (default value is 10), that minute is labelled as sedentary, otherwise, is labelled as active. Active and sedentary bouts are periods of consecutive minutes labelled as `active` or `sedentary`.
