The only detailed information available is information provided by the Hughesnet Usage Meter under the Usage History tab.
OR by going to My Account > Usage and then click History
From what I have seen, the Usage History doesn't show your data at the start of the day, but what you have remaining at the end of each day.
Hughesnet can't provide you information on what devices are using data, nor how much data you use on a website on a day by day basis.
If you wish to perform some troubleshooting, please let us know.
