I would like to be able to monitor how much time my child spends on the home network. The bar graph isn't very helpful. Is it possible to get more detail. Specifically how much time they have spent during any given period?
The Overview tab in xFi, will show the total network activity for the last 24 hours. If you select a Profile you can see network activity for the past 24 hours and past 30 days. If you select a Device you can see network activity for the last 24 hours and past 30 days. You can also view overall Data Usage by Month by going to More and scrolling down to the bottom of the screen and selecting Data Usage (this is the same data usage you will find in MyAccount).
