Shelly Plus 1 or Shelly 1L

    • Autor

    I have three wall switches inside the house which control lights in the garden. They are installed next to each other and wired as in the attached diagram - one "hot?" wire shared between each of the three switches, and then individual wires running from each switch to the lights.

    Am I correct that these are wired with no neutral and in that case I need to use a Shelly 1L on each switch (I have a couple of Shelly Plus 1's available)

    I do have available a neutral line from a wall plug which runs through the same wall box so I wondered if that could be used if necessary.

    Thank you.

    Do you have a three phase or a one phase mains network? How many RCD do you find in your distribution box?

    These questions shall evaluate the possibility of using the neutral wire from the wall box with a Shelly 1, which would be more convenient and stable as a Shelly 1L.

    Zitat von thgoebel

    a three phase or a one phase mains network

    I am not sure if it is three or one phase - I have a feeling three as the previous owner used to run some heavy duty machinery in the garage (welding etc). The house also has three separate RCD boxes - one for garage and outdoors, one for house, one for pool. Attached is photo of the RCD box in the garage where these three switches run to. 8 RCDs (plus two more out of picture).

    Many thanks for the picture and the explanation! Please check, if the lights in the garden and the wall box are controlled by the same fuse! If so, you may use the neutral from the wall box as supply for a Shelly 1.
