The Consumer Product Safety Commission is recalling more than 440,000 Nest(s goog) smoke alarms to fix a safety issue that could prevent the alarms from sounding in the event of an emergency. The recall is related to a feature that allows users to mute their Nest Protect by waving a hand in front of it. Last month, Nest halted sales of the Nest Protect because of the same issue, but today’s official recall means customers are eligible for a full refund. If you like your Nest Protect, an over-the-internet update to its firmware is available and should fix the problem. In a statement provided to Gigaom, a spokesperson explained:
Current customers can continue to use their Nest Protects once the Nest Wave feature has been disabled via software update. Even with the Wave feature disabled, the Nest Protect Alarm will continue to perform its essential safety functions, monitoring for increased levels of smoke and CO, and alerting users via voice alerts and Nest app alerts (if set up) as soon as there is a potential issue.
Oh, and if you were wondering how many Nest smoke alarms have been sold, now you have an idea.
