I successfully integrated control of wireless RTS roller blinds with SOMFY motors from both a hwqs and an hwi systems.
It took some time and effort to put together the xls driver file for illuminations but it was worth it. It have raise, lower, stop, intermediate position commands for all 16 groups.
I'll happily share the driver and details should anyone be interested. I accept payment in kind. Beer comes to mind but in in France so that might be tricky.
