I just buy wrong one....
I don't use dimmable litght, so I just need double switch 2. But I missunderstood the spec, so it happened
I live far away from Europe, so it's more expansive to return.
Is there any way to use dimmer2 as a double switch? or single switch?
Light's are LED with SMPS(Power supply) included.
And L = 220V, Neutral wire exists.
Thank you for reading this.
