Check this schema - Connection of the Stairway Switch with Shelly2.5

Hello,

Is my schematics OK?

Sorry for ugly drawing

Which settings should I use?

I suppose Edge switch and Restore previous state after power outage?

Thanks,

Michal

I was trying to do it, but the problem is, that I dont have all the cables for shelly in one box:

Red "circle" = one box

Green circle = second box - outside on the house - fasade - too less space, no phase wire, wet.

Yellow XX is the cable which is only in the second box, so I can't connect it to Shelly without leading those 2 new wires through my house. Those two XX cables are connected now.

Dammed, too late for a joke...

miso k : Are you really familiar with electric installation?

To be honest - I am not electrician, however, I have made some low-voltage electrical projects already.

I have changed SW and O now:

From logic point of view:

L phase and N should power Shelly all the time

If you can have phase on SW1 or SW2, shelly can react with switching on O1 or O2.

But probably Shelly2.5 can't detect O1 or O2 state changes on second switch.

Right?
