    Decided to replace my Lightwave connect series switches with the Lightwave smart series switches, to get greater LED compatibility and native homekit support.
    I thought the new Lightwave switches would have the same connections as the old switches, alas they do not.

    The 2-gang connect switches have X, S and L terminals for both "Master 1" and "Master 2".
    The 2-gang smart switches have S, L, N for "Dimmer 1" and X for "Dimmer 2".

    I currently have a 2-gang Lightwave connect series switch in my Kitchen, controlling the main ceiling light on the left switch and under cabinet lights on the right switch.
    Can any one advise on the wiring required for the new Lightwave smart series switch. Diagrams attached.

    Any help is really appreciated.

    Jase.

    I am fairly certain that unless you have a Neutral in the switch back box the new switches cannot be used.

    Neutral is optional for lightwave switches. I have fitted a 1 gang Lightwave smart series switch (no neutral) without issue, just the 2-gang I need advise on the wiring of.
