How to wire a Sonoff ZBMINI L2 Extreme for UK 2-way Light Switches

Hi @orangutan
In switch 2 how many cables did you have originally? If only 3 cables then grey and black in L1 and L2 are original but where 2 red cables comes from/into? Or you had 5 cables in switch 2 originally?

There were 5 in Switch 2 originally and the two red ones were moved to connect to the Sonoff device instead.

Installed Sonoff ZBminil today and worked. Very easy to follow thanks to the image . Thanks for sharing this image.
