Create a light Pulse for notifications

Just setup a Vera lite with inwall dimmer in my room.

So far I have linked it with Xbmc at nightime.

Created a wake up multi level dimming scene. That runs of Llama when Im home. Auto off when I leave home.

Looking to create my final scene I think, is it possible to send a pulse to dim up or down based on if the light is off on or below or above 50%. To account for if the light is on or off. I will tie this to prowler notification and perhaps txt msgs.

Anyone be able to point me in right direction?
