  • SW input controlled by a relayswitch

    Thank you Thgoebel for your link. I will have a look but I'm note sure that my limited notions in electronics will allow me to understand how SW input works.

    I was waiting for my second relay. I can say that it works with a second relay.

    Thank you utschu for your excellent idea. You're right. I hadn't thought about it, but it's true that I still have a second contact (after removing the neutral) that I could use. I will try and get back to this post.

  • SW input controlled by a relayswitch

    Thanks again for the answer. Unfortunately, it looks the same as the original schematic. The state on the app does not change.
    Thank you also for the explanations of the non-functioning of diagram 1 even if I still do not understand them.

    When the contactor is ON, I have 230V on SW. When the contactor is OFF, I have 0V on the SW.

    I can see that these voltage measurements are different than when I have a manual switch where I have 130V (??) on SW when the switch is OFF and 230V on ON.

    The operation of the SW input remains a mystery that is said to be solved with electronic knowledge.
    So, if you add a second relay, do you think it will work?Shelly 1 bis.jpg

  • SW input controlled by a relayswitch

    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.

    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?
