SW input controlled by a relayswitch

    • Autor

    Hello,

    i tried to connect the shelly 1 as shown in the picture so that the light turns on when the pump is on. It does not work. When the manual switch is activated, it has no influence on the state of the Shelly.

    Could someone please tell me why?

    I thank him in advance.

    Hello SebMai and thank yo for your answer.

    I'm sorry but I'm note sure to understand it.

    First, you said sw is permanently connected to N : When the pump is on (manual swich On), the eletrical relay is also on, so Sw must be L, just like the pump ?

    If I connect sw at the top of the electrical relay, sw will always be L and I'll lost the information that the pump is on or not and the bulb will always be on ?

    Am I wrong or do I misunderstood the explanations?

    yes and no it depands on the user screw, I meant this one from the switch.

    So if you turn on the pump with the switch than switches the relay and the input should work to.

    Not a nice edit from your picture but it helps :D

    Thank you for the time taken for this beautiful drawing;). It is very clear.

    The problem with your diagram is, that if the relay is out of order, I wouldn't know that the pump is not powered, and that's just what I want to know.
    I still have trouble understanding why my diagram is not working.
