Piston for dimming and turning off lights in the evening

#1

Hi,

I am trying to set up a piston that does the following:
IF certain criterias are met, THEN dim lights in room 1. Also turn off lights in room 2 and 3 but only IF no motion is detected, otherwise dim these lights as well.

I have created the first version of the piston, but for me it looks like room 2 and 3 are not connected to the first set of IF criterias (the “if” statement on the top). Am I thinking correctly?

EDIT:
So I messed around with “Only when”… Will this do the trick?

No, this will set those second two whenever the motion goes inactive. You have restrictions but no triggers for the first function. I would suggest looking at some of the example pistons on the forum here. I think you want to have the second two functions nested inside the first one, so the second two only fire when the first has fired.
