Detectionof Phillip wiz smart bulbs

I’m using a phillips wiz smart bulb in an outside PIR light
I’m using nmap device tracker to set the state to home and turn on another light with a shelly switch.
on nmap config I have set scan interval to 10sec, it will not go lower.
Consequently I have a delay of 5secs from the time the PIP light is switched until the second light on a Shelly switch is on,
Any suggestions on alternative method of detecting when the Phillips Wiz smart bulb is powered on ?
?? a delay of a couple of seconds would be OK but 5 is too log
