I've installed a sonoff mini and connected the signal wires to 3 3 way wall switches.
If I try to switch ON/OFF the sonoff using the app, there is no problem, it works like a charm always, but when I do it using the wall switches it just works "sometimes".
For what reasson can it be caused?
Is there any maximum length for the wires?
Should I activate any flag in the app?
Did you find a fix here? I can't get any of my switches to work at all.
I have a black and white coming in and the same leaving the box,
set of black and white going into l1 and n1 of sonoff and the other two coming from l2 n2
i connected three different switches to s1 and s2 and nothing happens
whitch wiring do you have?
someting like this?
or like this? sorry for double posting
