Controlling Somfy blinds (Down + Stop) / (Up + Stop)

Hi,

I got my Somfy blinds to work with Home Assistant using rfxtrx433e.

However, when I press “Up” og “Down” in the frontend, the blinds only move a few inches. On my Telis remote, I need to press “Down + Stop (My)” in order to make the blinds go all the way down. I can make this request through RFXmngr - is it possible to make the same request through Home Assistant - and how?

Thanks

EDIT: I figured out that my Somfy instructions were incomplete, which is why, it didn’t work. Used these instruction instead: http://www.automatedshadeinc.com/files/controls-somfy/rts-quickprogramming-2-09.pdf
