Flash led when a default route installed

RouterOS Scripting

Anyone have a script handy that can flash a led on a 433/493/750 when it sees a default route installed?

This script might help you get started. It counts the number of all routes. If the number goes up, it lights up leds and has a high beep. If the count goes down, it has a low beep. You can change it as you wish. Add a schedule to run the script however often you want.

# Detect when number of routes changes
# Tested on RouterOS v5.7

# set our global route count variable
:global lastRouteCount;
# get the current number of routes
:local currentRouteCount [ :len [/ip route find] ];

# if our global route count has never been set, set it now
:if ( [ :len $lastRouteCount ] < 1 ) do={  
	:set lastRouteCount $currentRouteCount ; 
} else={
# if the last count was less than the current, number of routes has increased
	:if ( $lastRouteCount < $currentRouteCount ) do={ 
# light up leds

	:if ( $lastRouteCount > $currentRouteCount ) do={ 
# low beep
		:beep length=100ms frequency=500; 
	}
# update the count
	:set lastRouteCount $currentRouteCount;
