Hi guys, I want to replace my 2 gang switch with a newly purchased Sonoff wifi smart switch. Thought it would be a straight forward swap, but turns out the wiring on my old switch is very different to the new smart switch.

Please see attached photos. The wiring on the old switch looks very complicated to me compare with the new one which only has N in, L in and L1 & L2 out.





I would really appreciate if anyone please give me some idea how I can replace this switch and wire it correctly?
