2 Gang light switch with a virtual switch

    • Autor

    I have two lights

    * One at the top of the stairs

    * One at the bottom of the stairs

    At the bottom of the stairs is a double light switch - Switch 1 controls the downstairs light, Switch 2 controls the upstairs light

    At the top of stairs is a single light switch - This just controls the up stairs light.

    I want both lights to be smart and controlled by Shelly 1L's.

    I want to replace the single switch at the top of the stairs with a double switch, but I don't want to add any new wiring, so the second switch I want to be connected to a Shelly 1L and used as virtual switch for the downstairs light.

    I think this means I will need to fit two Shelly 1L's each backbox? Could someone confirm if my thoughts are correct or if there is another, more appropriate way to achieve this?
