I want to connect 16 smd 50 GU10 3 W LED bulbs as I drew the diagram attached below. The bulbs are to be permanently connected to the dusk sensor, but I want to be able to turn them on using the switch at home and on the porch with a stair switch. Stair switches would be double to one light all the bulbs and the other and here I do not know how to connect everything so that only two bulbs on the porch that I marked filling the bulb field turned red. I would be very grateful for a hint what and how to connect and what I miss here so that it would not be that I turn on these two bulbs on the porch switch and suddenly also give current from the dusk sensor. I think I mixed it up a bit but maybe someone will understand. Nothing is done and bought, so someone can draw a better diagram.
