Hi there,

I'm scratching my head trying to find out how i can rewire my new smart switch.
I have an old 2-gang 2-way light switch with 3 terminals top and another 3 terminals on the bottom as seen with the diagram below with black, grey and brown wiring. L2 L1 L (top) L2 L1 L (bottom)

And my new smart switch only has only 3 terminals? L2 L1 L Are these switches even compatible?
