Thanks! Glad you like it.

Yeah, that’s basically what’s going on, there’s an “address” in each signal. Each channel uses its own address, and each Bond Bridge Somfy device uses its own address.

My first inclination is that your receivers on the few shades that don’t jog in channel #14 are “saturated”. Each receiver can only be paired with 12 addresses (whether that’s a physical remote channel or a Bond Bridge remote). Once it has that many, it will stop responding to the pair signal from a new remote.

Since you seemingly only have 3 addresses paired with these problem shades (channel #14, channel #16, and the Bond remote that matches #16), this seems unlikely, but I have seen it from other users. Maybe the receivers were paired with quite a few other remotes before purchase?

This is really useful information. With this, I can eliminate a few other potential causes in my mind: it’s clearly not caused by the distance of the Bond Bridge to the receivers, or by the receivers being a very old model that expects a slightly different signal.
