Back in April, Nest announced it would stop selling the detectors because it’s “Wave” feature — which is supposed to turn off the alarm with a wave if you realize everything is fine — had a tendency to misbehave, and turn off at other actions. That’s no good if there’s an actual fire, obviously, when every second counts.
Nothing like a little price cut to make everyone forget that its product didn’t meet expectations the first time around, eh? As such, there will be no wave feature on the new Nest Protect devices, meaning users will have to actually press a button to turn the alarm off. You can do it. It doesn’t hurt, promise.
