Two shelly 1L on same light

    Hello,

    I have some problems on updating my actual electrical system. For now the 2 wall switches are push-buttons that are activating a temporarized relay. I would like some advice on my below mounting idea. Will it work or make some damages ?

    My main problem is that I have only 2 wires that are going to each of wall switch and i can't put the Shelly 1L into the "Power supply" area because it is not covered by wifi... Maybe you have other idea to propose to me ?

    I would also like to avoid the fact that 1 of the 2 shelly gives order to the oder one to switch on by wifi request.

    Thank you in advance,

    Hugues.

    Welcome to the forum!

    To your issue: Arranging two Shelly 1L in parallel will not work - theoretically. But I don’t want to try it practically, because a faulty Shelly (or two) are very likely the end of the story.

    Could you manage to get the two wires 1.78 and 1.79 to box 1E9? By connecting the switch in box 1E11 to Shelly pin SW and Sx, you would have the issue solved…
