FitbitSleepHandler.py (class)
This module is meant to utilize all of the capability of the exposed python sleep api to analyze sleep patterns perhaps above and beyond what fitbit itself does.


These are my current 4 keys:
consumer: "66febeae096fe9442d10dd3e92d54de2"
consumer secret: "b8b002ddf50dd3525f57b9a350051b97"
reource owner:  resource_owner_key='20eb22828f652f729002ba0f855d07f3'
resource owner secret:  resource_owner_secret='48eaa2e1e11ea551d1e3579c3274cccd')


There is only one single sleep-related call made from an authorized client and that function signature is get_sleep(Datetime dt). This function returns a conglomerate data type of embedded lists and dictionaries.

If sleepUnitsDict is the main dictionary returned it has two keys, 'sleep' and 'summary'. sleepUnitsDict['sleep'] returns a list of one element which contains a number of dictionaries.

sleepUnitsDict['sleep']
sleepUnitsDict['summary']

The 'sleep' is a dictionary with these 17 keys:

logId
dateOfSleep
minutesToFallAsleep
awakeningsCount
minutesAwake
timeInBed
minutesAsleep
awakeDuration
efficiency
isMainSleep
startTime
restlessCount
duration
restlessDuration
minuteData
minutesAfterWakeup
awakeCount

Each key has a single value except 'minuteData' which is a dictionary of time values presumably used by other calculations. The 'summary'is another dictionary with these 3 keys:


totalTimeInBed
totalMinutesAsleep
totalSleepRecords

Therefore once you get the two parts of returned value you can get at the data directly by using these keys.

		sleepUnitsDict = authd_client.get_sleep(datetime)
		sleepList = sleepUnitsDict['sleep']
		summaryDict = sleepUnitsDict['summary']

		x = sleepList[0]
		dataitem = x['one of the sleep keys']

		dataitem = summaryDict['one of the 3 summary keys']
