Sorry if is repeated question, tried scrolling this thread + search function, can't find any related answer.

N years ago, my eletrictian asked me to get a no-neutral smart switch, so, bought a no-neutral wifi + rf433mhz 3 gang switch, installed with a capacitor on my first lamp, follow by another lamp and ac fan.

Recently the switch start to be not responding, probably due to wear & tear, thus, finding back a similar smart switch. I prefer the kind with 'press' function, not the touch screen type.

But nowadays, the 'press' type in the market thats come with Wifi + Rf433mhz are all 'Need Neutral', can't find any is no neutral.

So my humble noobie question
1. If there is a fan, does it means it actually have a neutral wire inside?
2. Or, if I die die install a Neutral require switch, what scenario will happen?

Thanks ya
The fan's neutral wire is usually connected at the fan there, instead of at the switch is it? I tried open my switch socket to see, all wire same colour, no idea about wat is wat.
If yes... then option (a) hard for me, also Google (b), yea, neighbour switch is aircond, seems very dangerous.

If so, no choice but to continue search for my favor design switch

Have browse through these, not suitable for me (just treat me as degil), coz whole house only using one smart switch for my bed room, for me to set timer, control lights & fan using RF433 switch on bed anytime, so no plan to add on extra device.
Still looking around, since I hard to pull wire & not to curi tepi wire, no choice then forced to get the 'touch screen' style smart switch.

Thanks btw.

Thanks for your help, but unfortunately, this is a vice device switch only, not the main gang.
