Shelly 1 - SW using Neutral

    Hello All!

    My first post so I'll start with a thank you for the forum. Very instructive.

    I'd like to double check some wiring with you all before possibly damaging my Shelly 1 as it's a 230V setup.

    During web searches I found "Fig1" as the means to drive SW using Neutral via push buttons.

    As I added in Red to that figure, is that wiring actually allowed? (Note the N and L going to the Shelly 1).

    I made changes "Fig2". Is this the correct and valid wiring?

    Thank you in advance!

    Hello, both are allowed and working for the current Shelly 1 (version 3). Shelly will detect a connection through the push buttons from its N or from its L port to SW as "active".

    When the push button goes to Shelly's N, the power dissipation is somewhat higher during the switch is closed. Thus, for static switches this is not recommended.

    Regards,

    Thomas.

    Thank you Thomas (t-600)! One question. Do you know why this configuration is not also in the wiring documentation of Shelly 1?

    I found that using neutral for SW is only documented in the Shelly Dimmer 2 documentation.

    Thank you!

    Hi Marco,

    you are right...

    When my brain serves me right, we (the members of this forum) figured out the different possibilities of wiring. It works well and solves many problems - but still it is not part of the official technical file.

    Viele Grüße,
