Any way to actually monitor traffic at the PC or network level for an individual user? I see a lot of odd behavior by TVs, IOT devices, connected bulbs and such

Any way to actually monitor traffic at the PC or network level for an individual user? I see a lot of odd behavior by TVs, IOT devices, connected bulbs and such. None of them seem necessary to me. I feel windows could do a lot better with reporting or allowing users to clearly see what is communicating across the network currently.
