I wonder if they would add this, as it would be a huge breach of privacy. If they were able to do this, then people might be even more concerned that Amazon is collecting that information since it would have to hit the cloud servers for your phone app to be able to see it.

I think for now I like the fact there is no traffic logging with eero, at all.

As i know there are various network monitoring software available that allow you to monitor network traffic in real-time. Some popular ones include Wireshark, PRTG Network Monitor, SolarWinds Network Performance Monitor, and Nagios. These tools provide detailed insights into network traffic and can often display traffic per device.
