Sonoff wiring for electrical shade curtains

[uragano47812]

Hello i installed new electrical shade curtains in my house. Before to the electrical system i was thinking to buy some Sonoff RF to include one in each curtain rolls. I have a question i will put the physical switch controls on walls as normal but i don't know if i have to put a second line of wires for each sonoff in parallel to have the double control possibilities (wifi or RF and physical switch).

Let me know what you think. I want to keep the system simple because i'm novice and eventually implement it with other devices and using domoticz.
