Can I see the data Alexa is using, up and down, on the network?
No. GlassWire can show there is an Amazon device on your network under “Things” and when it leaves/joins the network. GlassWire can also alert you when new unknown devices join your network.
If you use the Alexa app on your PC https://www.amazon.com/gp/help/customer/display.html?nodeId=202186050 GlassWire can show you its network usage in detail.
I’ll give it a try - thanks
