Question: If this was a simple fix (disabling Wave) for a convenience feature (waving instead of having to reach and hit a button), then why are they stopping sales? It would seem logical to update all unsold devices to disable Wave and continue on with sales. Safety concern, slightly. Nest has made note that this feature have never been compromised yet (then again, its the one time when the Wave does fail that caused a huge issue so this point is null). Also, the Wave feature does not affect the detection of smoke, only the resulting alarm. I think there is something else going on here. Possibly a more serious safety hazard. If a software update can solve the Wave issue, then why the stopped sales? If there are stopped sales, why not a more serious email/note or a recall?
