Smart switch installation

The newbie of technology · Aug 8, 2021

Hi, I’m new here and not so much of knowledge in wiring.
I’m trying to replace my old 3 gang switch to a 3 gang WiFi smart switch for my smart home.
I’m not sure which wire is the right one to connect to.
I’ve attached the original wiring from the old switch and the new smart switch.
Hope you guys can enlighten me.

The seller told me that it’s okay to use it for single fire line by just applying a capacitor to the L1

wire diagram as per attached. Hut I do not know how to wire them into the smart switch.

I would advise returning to the seller and get a unit the doesn't require a neutral or a capacitor adding to the the circuit. Have they made any mention of capacitor rating etc?
