Somfy blinds FUBAR'd

I’ve been controlling 2 somfy binds (bedroom and living room) without for months. Today, they just stopped working, either by the app, or by Google Home voice command. My Bond still controls a fan without issue.

I have tried:

  1. syncing my Google Home devices - no change
  2. power cycling the Bond - no change
  3. re-pairing the bedroom blind - this is a mess:
  • since the blind doesn’t respond at all, I can’t first unpair it, but have to remove it as step 1. Not sure what impact that has, leaving behind a ‘ghost’ blind, but presumably not a great one

  • I got to the stage where the app asks me to press the (un)pair button; I do so and, joy, the blind successfully jogs. But then when I go to test the blind functions in the app, it starts controlling BOTH bedroom and living room blind at the same time, even though the channel on the Somfy remote was set appropriately

  • I cancel out of the process, double-check the remote channel, and try again; the bedroom blind jogs, so I move on to testing the app controls. Now ONLY the living room blind moves, not the bedroom one.

So @merck, @jacob, and others… Was anything pushed out to the bridges today to cause this? What can I do to rectify it? How can I remove the ‘ghost’ blind?

Thank you!

If the receiver remembers twelve paired remotes, it’ll reject further pairing unless it’s factory reset, which is basically a special power cycle.

The last change to the Bond Bridge’s Somfy implementation was in January, and it was purely cosmetic. The last public release of any firmware was in February, if you’re in the Beta program: 3 weeks ago.

So I don’t think it’s related to a recent upgrade.

This sounds like an issue we patched in October. Remotes had a not-insignificant chance to be created with the same address. There’s also an internal counter for each remote, and when these counters coincide, the next remote used “wins” because the receiver tracks the higher counter. This’d result in one remote taking over two receivers, and the other remote not having any control, since its counter lags behind.

Once we discovered this it was immediately patched, so I’d be surprised if you’re experiencing this (unless you didn’t upgrade since October?), but it could be something along those lines.

If you PM me your Bond Bridge’s serial, I’d be happy to take a look and see if it’s this same “duplicate address” problem again.


The fact that they both stopped working makes me think it’s not the old “duplicate address” problem. I’ve got to think more on what this could be…

Thanks for the speedy reply, @jacob.

I’ve got it pretty much fixed now:

  • firstly, it seems that my firmware was out of date. I’m sure when I looked earlier today there was no notification about this, and in general I’m pretty good at staying on top of software changes. But I guess not in this case! So I updated to 2.10.21, saw various UI changes (‘up’ became ‘open’ with a new icon etc)

  • I think when I was trying to re-pair today I messed up my somfy channels, so that was my fault, unrelated to the Bond, and I corrected that eventually

  • I RE-re-paired (having to remove both blinds without being able to unpair first), and it seems like both are working fine now

So the outstanding question is still why both blinds became unresponsive to the Bond simultaneously, and without any obvious event occurring. Not sure when I last successfully used the Bond to control the blinds rather than the remote, but it was very recently - yesterday for sure if not today.

I can still PM you details of the device if that would help with troubleshooting?

Thanks again

Yeah, send them on over and I’ll investigate whether or not anything looks out of place.

Serial number sent! Thanks again!
