There have been a few devices giving troubles pairing with the C7. Check out these other threads, and see if any of that information helps. I think the same basic "fix" works for this same error no matter the device brand. There may be a fix coming soon, but hard to say when. So up to you whether to try these fixes below, or wait for an update. It sounds like the first few pairings are worse, and it gets better as you go, and it is only certain Zwave devices, so personally I probably would just work through it as long as I only had a few of these devices.
