Provide data usage per timeSpan in details

[coderbyheart]

Now that we have history, we can also share the usage per timeSpan in the sim details response.

That means that for each of these time
spans, return the sum of bytes used.

Property	Sum of bytes used
lastHour	in the last hour.
lastDay	in the last 24 hours.
lastWeek	in the last 7 days.
lastMonth	in the last 30 days.

Could it make sense to return the sum from 'lastHour','lastDay','lastWeek' and 'lastMonth' and in addition return hourly,daily and weekly averages which is calculated from the data from the last month/as much data as we have. As an example this could be:

dataUsagePerTimespan: { lastHour: 10060, lastDay: 211527, lastWeek: 1395739, lastMonth: 2691339, } averageDataUsage: { hourly: 6727, daily: 161468, weekly: 1130282 }

Where the first one is the usage summed up for each timespan and for the average I'm using all the data I can get from the last month and find the average from the first day I can find any data usage. (Ex if someone started to use the device only 2 weeks ago the average is calculated from the last two weeks instead of from the entire last month.) Or are you only interested in the last one with the average usage?

Yes, sounds good!

To clarify, the response should return usage per time last time span. The
initial description was misleading. Updated the description above.
