I have 4 switches for a couple of lights in my garage. There's no neutral wire, so I guess I have to use Shelly 1L.
2 switches have 3 wires and 2 switches have 4 wires and are marked with a "4 way" sticker.
How do I connect a Shelly 1L ? I tried to use the same scheme as with a "2 way" configuration, but it didn't work.
Thanks for your help!
