The company, which was acquired by Google earlier this year for $3.2 billion, stopped selling the Nest Protect last month after laboratory testing determined that the Nest Wave feature could potentially malfunction. The Nest Wave allows users to silence false alarms by wave at the detector rather than requiring them to manually press a button, which could be inconvenient for those with high ceilings.
The company has stated that there were no cases of smoke detectors turning off in customer homes, but that it wanted to be extremely cautious with such an important consumer device.
Nest and the U.S. Consumer Product Safety Commission have issued a "recall" to ensure that all affected Protects receive a software update to disable the feature. Purchased devices do not need to be returned to Nest and will continue to function normally, albeit with the Wave feature disabled.
Nest told The Guardian that the Nest Protect will be going "back on the market in a few weeks."
