There's the following setup in my bedroom:


I need to wire the WiFi Switch in the setup above so I made the following workaround:


Basically I dimissed Light Bulb 2 in order to get the power line to the WiFi Switch and I reversed the Lin and N (I assume that the switch links Lin and Lout when activated).


  1. Does this setup pose any risks?
  2. Is there a better alternative to this workaround? (I can't change how the wires are set up inside the walls; ideally I would get the N in the ceiling and the L in the wall).

    Why did the unmodified system use switched neutrals? That seems rather unlikely. – Transistor Dec 29 '18 at 14:36
  • Can you post photos of the boxes involved? – ThreePhaseEel Dec 29 '18 at 15:21
  • @Transistor: I guess that's just how the wiring was done (it's an old building). – Razvan Dec 29 '18 at 15:57
  • @ThreePhaseEel: Which boxes? This is the switch and here's how it looks from behind. – Razvan Dec 29 '18 at 16:09
  • @Razvan -- the places where the switch and lights are wired to the mains, basically (some places use boxes, others wiring roses) – ThreePhaseEel Dec 29 '18 at 16:24
