I downloaded the somfy module from crestron's website and made it SB compatible but after using it, I found that it was not working all together. So, I went back one step and just loaded the sample program that came with the module to the processor but no luck; Debugger was showing me that the hex command being sent to the shades from the processor was not the correct command as I saw it on the somfy set up program.
The problem was in the simpl+ program that is usde by the simpl windows group control module (I hope I'm not confusing you). The hex command that is sent out of the processor is a computation done on the group three byte hex address you input in the simpl windows module during programming. the calculation was subtracting each the address hex bytes from FFFFFF, in my case, my group address was 000001 and the resulting was FFFFFE instead of 000001, (do not know why it was done this way). After this, the program does two's complement to generate the 14 by hex command. After I fixed the line of code, re-sync the module, compiled and upload... Bingo!! It is all working now, UP, DOWN, STOP and 16 presets.
I'm using the PMC2 and a RS232 to RS485 converter from BB-ELEC.
