[Quattro_Systems 0]

Hello, 

 

I created following scene that turn off all the lights in my apartment:

This scene should be automaticly launched while button 2 is pressed 2 times on Dimmer in Lobby.

But it's not launching. It is properly running by mobile app. 
Does anyone knows what I am doing wrong ? What to check ?

 

Regards.

Did you enable in the dimmer parameter 40 and 41 to enable scenes activation? You need to do it first before the scenes can be launched by 2x clicking.
