Dear Mr's.
Sorry for English, but I think, that all guys will understand or in case polish answer I will use google translator.
Then this is my question.
I buy some units on BleBox dimmers. As I see, that logical input connection to N. Then I will upload picture with connection lines. Upper part is original connection lamp without BleBox. And into lower part I would like place BleBox close to switch. Then as I understand I need only pull through cabel from zero to switch box (cabel number 3)
Thanks and best regards, Stanislav,
