Instillation help

  • Hi All,

    Can anyone help me out with a Shelly 1L installation

    This is for a 1 gang 2 way switch.

    It has 3 wires

    Permanent live Brown Wire = L1
    switched live Grey Wire with Brown Sleeving = L2
    Black wire Brown shelving = Common

    I’ve tried myself several times, but either turning off the switch or the another switch disconnects the Shelly 1L

    Not sure if it’s my wiring or settings within the Shelly, please help me out.
