DHCPListenService as a trigger

I am using the network binding for presence detection.Pinging my devices is working ok but i want to use DHCPListenService also to make presence more accurate.When my devices connecting to my wifi i get

[INFO ] [work.internal.dhcp.DHCPListenService] - DHCP request for registered address:

at my log.How can i use it to trigger a presence switch with a rule?
