netwatch for mac addresses ??

I need for a script to be triggered each time a MAC address is listed , even for few seconds , in “wireless > registration” table
Netwatch works for ip addresses only, how to accomplish this ??
Thank you,

Make a script that will check MAC you wnat in registration list. Example for arp table is smth like this:
local simple [ip arp find address=11:11:11:11:11:11]
or smth like that.

You can check syntax in CLI.

thanks !
