From an IT background this would be amazing

Even the cheapest crappiest routers, mesh systems, etc I've had over the years had the option to track data usage by device and overall. Not sure why TP-Link has been unwilling to add this when so many people have talked about it. This should be a standard feature for ANY router or mesh system.

Would be really nice!

We need this!

100% agree with the lack of traffic monitoring

At least I would like to see real-time usage stats in the device list, so that we could sort devices by usage (last 24 hours, week, month). Also be able to see that data when you enter the device view. Of course having a comprehensive data analisys would be ideal, but basic stats would be highly appreciated. As other people mentioned, even cheaper mesh routers by other manufacturers have such features included.
