I have a retrofit system with a homework series 4 processor connected to a HWI-Q96 to control Sivoia shades. My question is, I can connect and talk to the HW processor via rs232 but the commands I send for the shades are not working. I am sending SVSS, <address>, <scene command>, <delay time> commands. The command seems to be accepted but the shades do not move. What am I doing wrong? Is this the right way to go about it? Can I send IP commands instead? Thanks.
