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.
