Fitbit Steps Summary

Sensor parameters description for [FITBIT_STEPS_SUMMARY]:

Key	Description
[TABLE]	Database table name or file path where the steps summary data is stored. The configuration keys in Device Data Source Configuration control whether this parameter is interpreted as table or file.

The format of the column(s) containing the Fitbit sensor data can be JSON or PLAIN_TEXT. The data in JSON format is obtained directly from the Fitbit API. We support PLAIN_TEXT in case you already parsed your data and don’t have access to your participants’ Fitbit accounts anymore. If your data is in JSON format then summary and intraday data come packed together.

We provide examples of the input format that RAPIDS expects, note that both examples for JSON and PLAIN_TEXT are tabular and the actual format difference comes in the fitbit_data column (we truncate the JSON example for brevity).
