    Hi everyone,

    I am running a shelly 1 + Temperature Add-on to control a 230V fan.
    The fan is simply connected to N directly and O from the Shelly.
    To the Shelly there is no external switch etc. connected - so only N + L & I (where L & I are connected to the same WAGO via 1,5mm wire)

    This works as expected - Shelly is reachable, I can see the temperature from the Add-On and I can turn on the fan from the shelly.
    Unfortunately as soon as I turn off the fan, the shelly gets unreachable.
    The only way I can get the shelly back online is by removing the power supply.
    Afterwards it works again as expected.

    I think the problem here is that the fan still rotates shortly after I turn it off and instead of consuming electricity,

    might create it at that point in time. Based on this "overload" the shelly 1 stops working.

    Any idea what I can do to prevent this from happening?

    Thanks for your replies in advance.

    I wonder how the current out of the fan during the bleeding could reach the Shelly: Due to the fact the contact between I and O is open (Shelly was switched off via command), the fan runs freely with no electrical connection to the live terminals of Shelly.
