Looking for direct component.
I think @Jtarche is looking for a device tracker. The pfSense stat monitor just pulls stats from the router, it can’t see what devices are on your network.
I am not talking about monitoring, just tracking devices for presence detection.
If using iPhone this will not fit your needs.
Presence detection is a hard topic, because the mobile phone is not good in rooms.
So going from kitchen to garden etc it will not work great.
