I am intending using the new resource of Sonoff Basic R4, called “Magic Switch Mode”. But my plan is using it with two switches 3-way. The intention is to use one or another switch to turn on/off the Sonoff Basic R4.
I think if I use a extension of the Line In connecting the two switches, it will work, but I would like to validate the connections with the experts.
Please, could you tell me if I am right or wrong? I put the diagram bellow.
