Smart switch wiring conundrum!
Discussion
Hi guys,
I’m pulling my hair out with this smart switch in trying to figure out how it should be wired. I’ve got an earth wire (unused), live and neutral and a switch that looks like this. Are any of these combinations right (scrap wire used for demo purposes!). Any help greatly appreciated - this should have been easy!

If your wall socket just has a single cable with what looks like live, neutral & earth, then that switch won't work.
There are 2 ways to cable for lighting - and most UK houses have the option that doesn't run a neutral to the switch. Instead the live and neutral are in the ceiling rose - and a single run of cable goes to the switch & you just switch the live. The neutral wire is supposed to have a sleeve on it to indicate that it is infact switched live, but often doesn't.

If you just have 2 wires in the wall box it will be a switched live like mentioned earlier.. You will then need one of these instead https://www.ebay.co.uk/itm/WiFi-1-2-3-Gang-Wall-To... No Neutral Wire is the key phrase
Surely better to forget a smart switch plate and use something more like a Shelly or Sonoff that's set up to go in place of ceiling rose wiring and supports a remote wired override switch? Keeps the circuits pretty much conventional but adds smart control.
Anything that tries to replace the actual switch tends to trip over the lack of wires to support it.

Sonoff make a switch that doesn't need a neutral: https://www.ebay.co.uk/itm/SONOFF-T4EU1C-WIFI-Touc...
Note: you may have to wire a small box (supplied) in parallel with the lamp if it's a low power LED

That small box is a capacitor, not tried one of these switches as I installed sonoff basics behind the ceiling roses many years ago before such things were available. I do have a sonoff switch on its way from China to try though just to see how it copesNote: you may have to wire a small box (supplied) in parallel with the lamp if it's a low power LED
