  • Hello,

    I would like to use my shelly 1 to turn on and off my light connected to an impulse relay (hager epn510).

    Is my wiring diagram good ?

    Is it possible to know if light in on or off with shelly ?

    :)

    Hello Cyril,


    the correct connection (if you don't like to substitute the impulse relay now) is the following:

  • Hi Cyril , welcome to the forum. :)


    Don't connect the output of your pushbutton to the relay. A better way is to connect it to sw of the shelly. ;)

  • Hello Cyril,


    WELCOME TO THE FORUM


    As Stefan already stated: The standard way would be to connect the output of the push button to the "SW"-Input of the Shelly and the "O"-Output of the Shelly to the impulse relay. Anyhow, even your suggestion would work, but you would not see at the Shelly App if someone switched on the Lamp via the push button.


    The most professional way would be to substitute the impulse-relay by the Shelly. You don't need it anymore. All current functions can be realized via the Shelly itself.

    Grüße Bernd

  • Thanks for fast replies !


    For now i don't want to sustitute the impulse relay.


    Sorry but Im not sure to understand :


    In first diagram > it doesn't work because 'SW' can't send impulse to impulse relay, true ?


    In second diagram > it doesn't work because i wont be able to turn off the light with app if iv turned it on with pushbutton, true ?


    in third diagram, impulse relay will receive 2 impulses if i use pushbutton ?
