Brel THW2015 (DD2702) 15-channel handtransmitter

I recently purchased the Bond Home, hoping it would be an all-in-one solution for my smart shades. However, I’ve only managed to get one of the three devices (a Somfy shade) working.

I also have outdoor screens from the European brand Brel. During setup, the Bond Home flashes green, which suggests it receives the signal, but the screens don’t respond at all. I suspect this might be due to a rolling code issue—but how can I solve this?

It seems like it should be possible. Strangely enough, the much cheaper Broadlink actually worked with the Brel screens, though it had other limitations.

I’ve attached a photo—curious to hear your thoughts!
