Support of Somfy Chronis RTS

I want to control my Somfy shutters with Homey. Currently I use the shutters with the timer/remote control Chronis RTS from Somfy. In the Somfy App this device isn’t listed.
Has someone experience with this configuration?

You cannot add Somfy remotes to Homey. What Homey does is emulate a r emote in order to control the So add the shutters instead. You do need the remote to get the shutters in programming mode though.

This means I should connect the shutters directly via 433 MHz by using the programming mode, right?
Thanks for this hint!
