+Version 5.3.1 Update
+
+I just discovered that it is possible to determine which scene is turned on in the eventstream.
+
+A new subflow is added in the flows folder: flows/scene_active.json  
+Simply add the discovered scene ID and it gives you a true when the scene is turned on.
+This might be come useful in some scenarios.

 I made an all-in-one Subflow for: Candle, Fire, Alarm Light, Alarm Group, dynamic Scene effects. It is pretty convenient to use.
