Last month, sales of the Nest Protect smoke alarm were suddenly halted after the Google-owned company discovered a malfunction with one of the product’s key features. By design, a simple wave of the hand under the device was able to manually turn off an accidental alarm.

Nest discovered that the feature could be triggered by accident, which could result in some seriously dangerous scenarios. Now Nest is recalling all 444,000 of its smart smoke alarms with plans to have the device back on the market in a few weeks.

Like Nests’s futuristic thermostat, its iPhone-controlled smoke/carbon monoxide detector looked like the perfect replacement for the antiquated systems used in most homes today. It turns out that the Nest Protect was a little too good to be true.

Since the device went on sale in November of last year, Nest has discovered that one of the Protect’s hallmark features can malfunction. And that happens to create big safety concerns. Until the issue is resolved, Nest Protect sales have halted.

Nest Labs, the company that was founded by “father of the iPod” Tony Fadell, is famous for reinventing the home thermostat with the pretty little Nest device launched in 2011. But now the company is hoping to expand its presence in your home with a new, $130 smoke and carbon monoxide detector called Nest Protect.

Instead of just beeping at you, Nest Protect provides vocal alerts that will inform you just how dangerous the conditions in your home may be. And if it goes off accidentally — as ours often does when my wife is cooking — you can silence it just by waving at it.
