I think that's highly router dependent, but here's what I know. Home Assistant can monitor some things via the UPnP/IGD integration [1]. If you're looking for something more advanced, you could look into SNMP Exporter [2] with a Prometheus + Grafana setup. Another option is to set up a PiHole DNS server, which would both block ads for the local network, and give you DNS statistics on a per-device basis. None of these can get to the level of granularity you can get with a pcap based tool like sniffnet, but they're a good start to network monitoring and should work with most home routers. If you really want to go deep with your network monitoring, you could set up a more sophisticated using OPNSense/PFSense, but at that point I don't know what is and isn't possible as I have no experience with them.
