snmp_exporter

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.

I recently setup Victoria Metrics + https://github.com/prometheus/snmp_exporter + Grafana to get start tracking bandwidth on my top of rack switches in my Datacenter rack which has been a pretty awesome setup. The way you can auto generate a config for your SNMP MIBs with SNMP Exporter was unexpectedly not a terrible experience. My next task is to get centralized logging going with Victoria Logs + Vector, I'll have to check this out once I get everything setup. I believe I can use LogQL with Victoria Logs but I haven't tried it out yet. https://docs.victoriametrics.com/victorialogs/logsql/
