Shelly 1 - Connecting to a 12v Light / Fan (Halloween inflatable decoration)

    • Autor

    Hello All

    I am planning on using a shelly 1 (already purchased) to control a Halloween inflatable - I have switched the shelly to run on 12V DC with no switch (literally the shelly is going to be used to turn on / off via home assistant)

    I have the current wiring as follows

    12vDC psu + to N(+)

    12vDC psu - to L(-)

    SW = empty

    I = + on Halloween Inflatable

    0 = - on halloween inflatable

    I am able to log into the shelly, configure it for wifi - I hear the click of the relay when i turn the switch on but nothing happens

    I have also tried the following configuration:

    12vDC psu + to N(+)

    12vDC psu - to L(-)

    12vDC psu - to SW (Jumpered from L(-))

    I = + on Halloween Inflatable

    0 = - on halloween inflatable

    again nothing happens

    What am I missing here?

    It seems, you have not understand the working of Shelly1,

    ...

    is wrong.

    Shelly "On" --> electrical short circuit of the voltage

    Please have a look in our lexicon. There you find the diagrams. In your case have a look the penultimate picture

    Good luck.
