Fitting A Smart Wifi 3 Gang Lightswith

[j0nb0y]

Hi, Has anyone on here swapped their tradition light switch for a wifi controlled one instead?
I am contemplating swapping my manual light switch for a wifi controlled one, it is a 3 gang switch which I am thinking of replacing, the wiring diagram shows that it must have a neutral going to it. My current switch has a live and a switched live plus an earth wire. I can run a neutral from one of the junction boxes in the loft feeding one of the lights, would this suffice? Then all 3 permanent lives in one terminal and the other 3 switched lives in their allocated terminals? Is this correct? Or would all 3 cables feeding the switch have to have a neutral?
Hope the above makes sense.
Cheers in advance.

I've no experience of wifi switches, jonboy, but what you suggest would be fine. The only proviso is that the neutral must be the same as the one going to the lights. Otherwise, problems could arise from a "borrowed" neutral.

The Builder is absolutely right (he always is). It won't apply to you because you're going to take the neutral from the lighting circuit; if you took the neutral from the ring-main I think it would still work UNTIL YOU SWITCHED OFF THE RING-MAIN CIRCUIT (or the breaker tripped). At that point you would lose the neutral and the wifi switch wouldn't work.

Cheers for that The Builder and bhg481, I thought it was correct, but always best to check. Yes, the neutral in this incident will be coming from a junction box in the loft which is part of the lighting circuit, so no probs there.
