Hello,
I working on a project in which I have 5 somfy ST-30 rs485 motors. The brains of the system is a PMC2 processor. The problem I'm having is that the module available on crestron's website is not system builder compatible and I have not been able to make SB compatible so that it works correctly. Has anyone here integrate somfy shades before? does anybody have a system builder compatible module that can share?

Thanks.

After three days of trial and error, I finally got this working!! if anybody ever comes across this and needs help, just ask!!

Were you able to fix the module? I had a post on here a couple of weeks ago on how to make a module system builder compatible.

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.

Nice, you should tell crestron tech support about it so that they can fix the module so no one else has this problem.
