Somfy RS-485 Protocol

[Joep]

Thanks for your answer and sharing your code. My biggest issue is how to set the correct channel? How is this done? First with a Somfy remote and once paired you can also control it by the script or how does it work?

Only address is needed for control by script. If you need RTS channels check rs485windowSetChannel function or remote controller.
Also I think you should check your motors documentation first for proper initial installation.

Thanks Bitver. That helped me.
