Ad soldering at the Somfy remote: I put one wire to each of the 4 buttons (up, down, my, channel). In addition, I soldered 2 wires for the power connection (GND, 3.3 V). So, 6 wires, nothing more. Just let me know if it is still difficult for you to identify the wires on the picture. Supplying the remote control by the RPi is optional. You could also keep the battery of the remote control and just connect the GND line (but I do not see an advantage and reason to do so).
Are you using limiting resistors or just connecting directly to the GPIOs?
No, I do not use resistors or other components. The wires go directly from the buttons to the GPIO pins and the supply pins are also directly attached.
My system is in operation now for more than 3 years. No problems so far, it works well.
Thanks a lot for your feedback. I'm currently performing something similar but with a normal single channel Velux remote. I'm going to need to control 2 additional binds (3 in total) and instead of buying 2 more remotes, I was thinking of using a Somfy 5 channel remote (like in your project). But I then saw that the Somfy Telis 5 RTS is actually more expensive than the 3 normal single channel remotes, so I think I'll just replicate the GPIOs on the RPI.
Advantage: No need to worry about changing the RF channel nor worry about the channel switching delays. Disadvantage: End up using more GPIO pins on the RPI (open, close, stop) x 3
Can you please provide the connection diagram on the Somfy remote - which terminals on the Somfy remote did you solder? (the picture you provided is difficult to see)
