    Hi there,

    I'm renovating my house and want to include smart lightswitches to control all the lighting in the house.
    The main issue with doing this is that all the best smart light switches require a neutral wire in order to work. I'm planning on having the house rewired, so can get this sorted, but it appears that the device I'd like is only rated to work with a 120v supply.
    I'm wondering if doing this would meet regulations (and if it is even possible to run 120v on the lighting circuits) and also how this would affect any bulbs that I would want to use? I'd like to predominantly use LED dimmable lighting..

    thanks in advance

    Highly likely that it will not function properly

    Welcome to the forum mate.
    Seems like you are making thinks really complicated.
    What is the American product you are interested in and maybe someone could suggest a 240V version.

    USA has alot of these smart light switches.
    There are a few different protocols available, on the entry level market you have 3 major ones here in the UK.
    Zigbee, Zwave, RF these are also available in the USA but they use a different frequency in I believe they use 902 to 928 MHz in Americas and Australia and 868 to 868.6 MHz (Europe) ISM bands.

    Its illegal to use 902-928MHz devices in the UK which limits what devices you can buy, over here people tend to use Lightwave RF as its easy and works out of the box.

    Personally I find them a bit flaky.
    You could always go for a more professional system.. Gira (lighting only), Loxone or KNX but the money more than doubles.
    Have a look at

    Don't run a 120v lighting circuit. Please don't. We will be disappointed in you.

    I put 120V rather than 110V to see if George was on line. Is that wrong of me?

    I somehow don't think his DNO will give him a 120v supply.
