This is what it says on your help page: you can use the Panoramic Wifi app to see which devices are using the most data in your household where is this option?
Forum Discussion
In case anyone finds this thread because they have the same question, here is the official answer:
I believe the app was recently updated it will no longer show how much data each device is using it will only show the time spent online. https://www.youtube.com/watch?v=spj-I-8_3UQ shows where it used to be available about 1 minute into the video. This is meant for parents to help limit screen time for children and to see if they are using the internet at times they should not. The only monitor for actual data usage I'm aware of is the overall usage for your network that can be displayed with the data usage meter. I have alerted our marketing team to let them know our website needs to be updated. I have also submitted a feature request to see if we can get the options back to measure actual data amounts and not the amount of time
