Shelly scene "come and go"

    Hello,
    I don't speak English very well, so I use the google translator, sorry if everything is not translated very well. Do not hesitate to say it and I will change my sentences with pleasure. ;-)

    I use the Shelly device a lot and I am delighted. I am looking for a sollution to manage the light of a room. I have a switch and a Shelly 1 module connected directly to this light and another switch that is just on. I thought I could simulate a "come and go" (I don't know if it is said like that in English). But I can't seem to find the right settings. I'm sure I'm not the only one in this case. Can you help me ?
    Thanks in advance

    Not sure i understand well, but if you have an existing wiring for the 'come and go' (va-et-vient?) then you could wire it on the SW of the Shelly1. If you do not have an existing 'come and go' wiring to the second switch then you probably need another shelly 1 that will communicate with the first one (via URL action for instance or with a scene if you use the Shelly app).
