I already have traffic analysis enabled. I have gigabit fiber. It doesn’t show totals as it resets to zero automatically if throughput isn’t substantial. It’s not a running total. I wonder if I put a Unifi AP between the Edgerouter and Orbi APs...
The UniFi AP would need to feed the Tesla. Network devices can only get data on what they talk to directly. And yeah, the router is focused on routing and not on keeping stats, so it is a very short rolling window.
Knowing far too well how WiFi works, I wouldn't touch Orbi with a ten foot pole and somebody else holding it. They try to make "Easy Peasy" mesh networking without understanding the downsides to such a thing in the hands of somebody who doesn't understand how it works. I would only give Orbi to people I didn't want to talk to anymore or didn't like.
So if the Tesla is connected to an Orbi (along with other devices), only the Orbi would be able to tell you what's going on.
