I’m not a Pro, but a consumer hoping to get a little help. I purchased an automated shade set-up from an installer who went bankrupt before my job was complete. I’m fortunate that most of the work was done, but there was still some programming that needs to be complete. I’ve been working on this myself based on the instructions on the Somfy website, but things are not lining up quite like I would expect.
All of the motors are Somfy Sonesse 30s and all of my wall panels are the DecoFlex WireFree multi-channel panels. I’m having problems in multiple rooms, but the living room is most illustrative so I’ll use that as an example. The living room as a total of seven different shades, three of them are on one set of windows facing west and there are two each on a pair of windows facing north. Right now all of the each set of shades (west, north 1, north 2) are controlled with channels 1,2,3 respectively. I would like to change it so that channel 1 controls ALL the shades and 2,3,4 control the individual groups.
So I set about attempting to program the western set of three shades to respond to channel 4. This seems like a simple task of adding a new channel to those shades, but here is what happens. When I put the panel into program mode only two of the three shades ‘jog’ to acknowledge the programming command. I can successfully add channel #4 and get those to shades to respond to commands from channel 4, but never the third shades. All three shades continue to respond to channel 1.
Is there any reason the shade wouldn’t respond to being programmed? It is obviously functional.
The same issue is occurring on all the other sets of shades - one shade responds to the programming command, the other ignores it.
I’d be grateful for any help I could get.
