  • Hello,


    we have a device with a 12V controller.

    The controller has 2 contacts (normally open).

    If the contacts are open, the device is enabled (ON).

    If the contacts are closed, the device is disabled (OFF).


    If I use Shelly 1 to open / close the contact, it works, but:

    - when I see ON in the App, our device is OFF because the contacts are closed;

    - when I see OFF in the App, our device is ON because the contacts are open.


    Is there any tricky to invert this behaviour in the App?


    Thank you

  • Hello mirko.cola, welcome to the forum. 😊👋


    Reverse input under Buttontype might solve your problem.😉

  • Hi, thank you for your answer.

    I have tried, but it is the same.

    I think the "Button Type" settings in the App are related to the button connected to SW contact of Shelly.
    I have connected only I and O, there is nothing on SW.
