A possible solution is scripting a network wide NMAP scan and using -sV to
grab banners.  That would give a general understanding of what the devices
on your network are, and what they are doing.

This will leave a pretty large footprint and generate a fair amount of
traffic depending on the number of devices out there though and assumes
that the IOT device is not running some sort of firewall.

Some of the NMAP plugins might give further information as well, and the -O
"OS fingerprinting" plugin can give some interesting information, but is
not 100% accurate.

A better long term solution would be to have a central syslog server that
you can get your network equipment to log to, to determine when new devices
are deployed on the network.
