Light Switch Wiring

[hem30]

Hi,

Need some help please. I'm changing my living room light switch to a wifi one and need some help with the wiring. The existing set up has two switches either end of the room.

I have attached the photos of the main switch and the new wifi one.

Please help. Thanks

Sorry - can't be done - no neutral.

Ive just checked the other switch and that has just 3 wires connected which i presume the blue one is the neutral? If thats so, can i connect it here?

Nope ,the blue is a switched live . No neutral there.
Your metal switch plates must be earthed ,and they are not !!!

Oh ok, thanks guys. Is that common for there not be a neutral on a light switch? Can it be done another way or what are my options?

Plus - the new switch isn't suitable for the two-way switching.

Ok, thanks. Thats that then.

You should worry more that they are not earthed !!

They are both earthed and they are connected to the metal back plate! Phew!

Not on your pics ??? If you mean the earth conductors are terminated in the mounting box ,that is not earthing the switchplate .

I see what you mean terryplumb, I will have to get a professional in to have a look at it quickly. Thanks

The earth conductors should go to the earth terminal on the switch plate . A seperate ,short piece, of earth cable can link from the switchplates earth terminal ,to the earth terminal on the metal mounting box. Many consider that to be good practice ,however ,if the mounting box has a fixed lug it isn't really required.

You can get wifi switches which don’t require neutral.

Wouldn't recommend it though. They can be very flaky.
