I am trying to control three Somfy RTS blinds using eDLT switches. I am able to control each of the blinds through the 5500SHAC with the Somfy RS232 transmitter. I am also able to control the blinds using my smart phone. However, I would like to control each blind in each room using the eDLT switch. I have set the switch to a shutter relay. It is my understanding that this works with a shutter relay. Somehow I need the switch to send RS232 commands (I think) Any help would be greatly appreciated.
