Smoke alarm company recalling more than 400,000 smoke alarms

A Google smart-homes is recalling 440,000 smoke alarms due to a feature that could prevent the device from going off immediately.

Nest alarms have a function that allows users to temporarily silence alerts by waiving their arm near the unit.

The company is asking all users to connect their device to the internet through a wireless network to get the automatic update.

Users should confirm the update by going to “Nest Sense” on their account and making sure the “Nest Wave” function is turned off and grayed out.

“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 [carbon monoxide], and alerting users via voice alerts and Nest app alerts (if set up) as soon as there is a potential issue.”
