Essentially the title.

If only S2 (previous connection point from light switch to bulb) is truly required, then, wow, that makes things way easier to install.

I guess electrically it makes sense, I’m just weirded out it does not show in the instructions.

    It depends on your needs. Either wire the switch between s1 and s2, or between Line and s2

      After some research, all I’ve gathered is one report saying that you’ll absolutely destroy the Sonoff if you try to do that.

      I reviewed the Aqara manual, and the possibility is specified there, so that makes it quite probable that it simply is a forbidden configuration for the Sonoff, or even any smart switch that does not specify that possibility.

      So, unless someone magically shows me it’s possible, I am avoiding it for now, I’ll learn how to pass cables through the tubes and avoid any burning for now 😅

      The reasoning behind the “it will NOT work” is that Sonoff uses S1 and S2 to create a low voltage circuit. It’s expecting low voltage, so it might break due to a voltage overload.

      Here’s a reference.

        S1 and S2 are only for the activation switch. You connect the actual device that gets controlled to Line Out.

        If your setup doesn’t require a physical switch, then nothing gets connected to S1 and S2
