Voltage on I at the same time as SW

Hi,

so normally connection diagrams show that we connect L to L, N to N and L to I. Then when we have L on SW relay is closed and there is voltage from mentioned I(input) to O(output).

I would like to have voltage on I at the same time when it appears on SW, so I has voltage only when SW(switch) is on and then and only then from mentioned I(input) to O(output). I know it wouldn't be possible to use for example command from Home assistant but are there any drawbacks of this solution?

Thank you,.

I have also done some tests and SW is preloaded with ~127V (I think because it is possible to use N to swich ON).

Because of that, after switching OFF, connected bulb is still halfway ON.

WOW, great. I have swapped L and N which powers the Shelly and now it works as expected. BIG THANKS
