DHCP leases monitor for pfSense

An offering for the community…
routermonitor pulls the current DHCP leases from pfSense and saves them in a database. For new devices on your network, routermonitor sends a text notification. In many cases, an IOT device hostname is unintelligible, so routermonitor supports adding notes to the records. The set of records can be listed with sorting on all fields (MAC, hostname, IP address, IP expiry, and first seen), and searched for any string.

I've been running this tool on my network for over a year. It pretty much solves the "what the heck is that device?" problem. Originally written for dd-wrt, it needed an update for pfSense support. I run it as a systemd service with updates every 15 minutes. This is a CLI tool written in Python and supports the latest pfSense+ and CE versions.
