Hello all. My knowledge stops one level before ;). I have attached 3gang 2way switch and I would like to know if I can use only one smart wifi to replace only this one. 1 gang is used by outside door , the second by two ground floor lights but 2way with the 2nd 2way switch and the 3rd gand by 1st floor light with the 1st floor 2way switch. Can anyone help me with this project? Thanks

The most obvious question is do you have a neutral at the light switch ? your smart switch needs it to work.

It works with or without neutral. Also if you can see at the 1st picture inside the box there are two neutral cables, right?

No you cant use the smart switch as it does not have two way switching.

I dont know of any smart switches that will work with ordinary switches, if you change all the switches to smart switches there are plenty on the market that can do this.

A 2,3,4 gang switch is 2, 3 or 4 individual switches in one package, the switch you show has all three switches using the same live, so would not work when the lights are on different circuits, as one of the lights would end up with a borrowed neutral.

However you can fit a relay at the lamp.

The instructions are for a relay, DSC_6061.jpg seen here, the switch ends up switching extra low voltage, and it changes what the light does when switch changes state, does not matter is switches on or off, the change of state turns light on or off as does the phone so phone is like another two way switch. DSC_6060.jpg this is box, in my case a double relay, so can switch centre lamp independent to outer lamps, DSC_6059.jpg not yet fitted only tested, should go up next weekend.
