Wiring Shelly 1 with somfy garage door control

Hi

Could you help me with cabling the connection of a Shelly 1 for the garage door controller? It is a somfy RTS 1000

I found this installation in some tutorial on YouTube but I must have done something wrong …. Because it doesn’t work. The cables connected on 16/17 come from the wall interruptor (which I would like to keep)

Could you advise where I should connect L, N, O and 1? Thank you!

Clarification. I have currently connected L/N in 3 and 4, and 1/0 in 14/15… but this doesn’t seem to Work

Thanks! Then where do I plug the cable from the wall interruptor that arrives at 16/17?
