Nest Labs, the home automation company recently acquired by Google for $3.2 billion, said Thursday that it was halting sales of its smoke and carbon monoxide detector over safety concerns.
Tony Fadell, the chief executive of Nest, said in a letter posted on Nest’s website that it would stop selling the product, Nest Protect, until it fixed a problem with a feature that lets people temporarily disable the alarm by waving their hands in front of the detector. Fadell said Nest was concerned that the feature could be unintentionally activated, potentially delaying the alarm from going off if there was a fire.
