Uncomfortable Nest “Recalls” Smoke And CO Detectors Due To Alert Failure

Whuh-oh. In the quest to conquer the Internet of Things (IoT), Google’s Nest just had a hiccup; Nest Protect Smoke + CO Alarms are being “recalled” by the U.S. Consumer Product Safety Commission due to an alert failure problem.

The issue is that the Nest Wave feature, in which a user can wave his or her arms near a unit to cancel a manual test or silence an alarm, can accidentally cancel a real alarm during an emergency.


We put “recalled” in quotes because users don’t actually have to send the units back; they’re not faulty, they just need a software update to turn off the Wave feature. All you have to do, according to the CPSC post, is connect your Nest device to your Nest Protect account to get the automatic update that disables Wave. To double-check that you have the update, you can go to your Nest Sense web or mobile app and see if the Wave button is off and grayed out.

Aside from that, your Nest device is totally fine, but it’d be a good idea to go ahead and take care of the Wave issue at your earliest convenience.
