This company J. Geiger makes some beautiful shades, but has a Frankenstein method of control.
They have Somfy motors and use a Crestron processor to receive RS-232 commands.
I've built a dummy program. I've added a QSE-CI-NWK, the Lutron device which enables RS-232 communication. Under "Configure Integration," I've added a selection of commands provided by J. Geiger. I can't find anywhere to add shade groups (though that may all happen on the J. Geiger side of the puzzle). In the HWQS program and I can't find anyway to send the commands I created.
