I have, using the new CM11A code. Triggering lights from the floorplan is pretty quick and reliable, however it is not possible to create very advanced rules. For example I was not able to create a rule to turn a light on when I enter a room if it's night AND media is not being watched in a room AND the house is not in sleep mode. See this thread:
