I want to connect a Shelly plus 1 to a light switch, but I have realised that in this house only the line wires are going through the switch boxes. The neutral wire go directly to the lamp on the ceiling, so I have no neutral wire to pass on to the Shelly inside the light box.
However, right underneath the light switch I have a power outlet which does have a neutral wire in it...so my question is, can I extend the neutral wire inside the power outlet and bring it inside the light switch box in order to power the Shelly plus 1? Or do I absolutely need to extend the neutral wire back from the lamp instead?
Thank you.
