Wishlist: Per local IP bandwidth usage

[StackKorora]

I'd like to better track how much data some of my IoT devices are using. I can pull this information manually per IP to see and it is in the interface when I look at the connections, but I've not found a good way yet to automate it and pull it into Zabbix (I was thinking of it being a discoverable item to auto-add in IP's and then forget about them if the IP hasn't appeared after a while).

Thought I'd toss the idea out there and see if anyone else had a good thought/suggestion.
