Clever way of "auto off" for Fibaro Wall Plug

[mmjoy 0]

I recently exchanged Coolcam wallplug with Fibaro Wall Plug. Unlike coolcam, Fibaro does not have the "auto off" feature which I used for heater in bathroom (if turned on, turn off automatically after 2 hours). I initially created the magic scene to auto off after 30 minutes, however it is a scene, and my kid likes clicking that button many times, which resulted in message about multiple instances of the scene running.

Do you have any "clever" ideas how to prevent that from happening?

If you can code in LUA, here's an idea....at the start of the code, check to see if another instance is already running, and if so, abort this scene's execution.  That way, every extra click by your kid is ignored. Code is shown here:
