So.. thankfully found this forum, but didn't find the right answer. Unfortunately I have different kind of setup for outdoor lights switch - it connects 6 outdoor lamps somewhere in house, and it seems there is no (?) neutral wire. I added image to post.
I tried connection diagram "special" but couldn't get Shelly1 up.
Brown line is L (always on). Blue - neutral (no power)? I have possibility to take another L line from switch beside.
Any suggestions? I don't plan to use this as normal switch, but to use Shelly 1 and OpenHab for turning lights on/off.
