Hi tried to made a scene, but after many tries, I didn't succeeded.   Problem: I have a Fibaro  Sensor and and Lamp dimmer in the hall. I made a simple scene, if Sensor detect movement automatically the lamps starts to burn to X seconds.  But I like to make to real time. If movements, the lamp has to burn for X seconds, but for new movements the counter has to be reset to X seconds.   So If people are moving in the hall, the lamp should be switch on for X second. So
