    Yep – realised that yesterday – it’s weird that it is the closest working solution, though. I’m hopeful of just a wire swap somewhere for the slave

    Cheers for the reply – my sparky found this on Lightwave’s website https://support.lightwaverf.com/hc/en-us/articles/115003011932-How-do-I-wire-2-Way-Smart-Series-dimmers- (mine is the three wire example)

    It works in the sense that the switches both go orange. The master can control the lights. The slave knows the state of the lights, ie. goes blue when master turns them on, but will not actually control the lights itself.
    Lightwave think the slave is faulty so a replacement is arriving today.

    If not – I’ll ask the sparky to tidy up the slave wiring and I’ll bang a wireless switch where the slave currently sits.

    It could be you have what is known as a 2 wire arrangement for these lights. I don’t think that is compatible with Lightwaverf normal gen1 master / dimmer operation which expect the normal 3 wire method.

    See http://www.lightwiring.co.uk/two-way-switching-two-wire-control/ for explanations of 3 wire and 2 wire systems and why the 2 wire method is a bad idea in general.

    If you can’t change the wiring to suit then an alternative would be to wire the dual gang master as a standalone and then use a dual gang wirefree slave which is battery powered and paired with the master to allow it to control it.

    Hi – I’ve just had my sparky out today and he’s not sure how to wire my kitchen 2 gang master with 2 gang slave.

    The diagram assumes there’s a “from lighting circuit”, which I don’t have. With his attempt, the slave powered up (didn’t actually do anything to the lights though), and the master remained off.

    How can I wire them up?

    Master old switch:
    Gang1 – Brown in com
    Gang1 – Black in L1
    Gang1 – Grey in L2
    Gang2 – Brown in com
    Gang2 – Black in L1
    Gang2 – Grey in L2

    Slave old switch:
    Gang1 – Brown in com
    Gang1 – Black in L1
    Gang1 – Grey in L2
    Gang2 – Brown in com
    Gang2 – Black in L1
    Gang2 – Black in L2

    He tried a combination, but I’m not sure what it was. I know Brown was in L for each, though.

    I’ve also tried the Master switch on another light upstairs to make sure it wasn’t faulty – it worked fine.

    I rang Lightwave but Richard the in-house sparky isn’t in today. Any advice/ideas?
