If you have a Somfy Telis 1 RTS you can wire it your Raspberry Pi and control all of the buttons remotely. Since it requires soldering and some cables, I like to call it hotwiring your Somfy :).

You do need a remote that is already programmed to work with your shutter.

Simplest would be if you have a case to put the board of the remote in.

1. Remove the casing and battery
2. Get 5 jumpwires (female to male)
3. I like to use pins 1 and 9 for the power
4. So you can use 3, 5 and 7 for the up, my and down button
5. Solder all of these male ends to the board and plug the female side onto te GPIO

It should look somewhat like this:

No you are ready to go, either use the UI config or add the config manually.

Sample of the config used in the README. Movement duration is best measured as the time it takes to move from up to MySomfy position in seconds, you can adjust it to your liking.
