Last month, the folks at Google-owned Nest alerted owners of the company’s Nest Protect smoke and carbon monoxide detectors that an software glitch could, under very specific circumstances, cause the device to delay sounding the alarm. Today, the company and the Consumer Product Safety Commission made it official with a formal recall announcement.

As we mentioned in April, the detector’s “Wave” feature — which allows the user to stop a sounding alarm by waving a hand in front of the device — could inadvertently be activated, causing a delay in the case of an actual fire.

The Nest folks said at the time that they had discovered the glitch while doing testing in their own labs, and that it knows of no instances of anyone being harmed.

Nest Protect owners whose alarms are connected to the Internet via their building’s WiFi network have probably already received the automatic software update that disables the Wave functionality.

You can confirm that your Protect has been updated by going to Nest Sense on your Nest account mobile or web app and making sure that the button for Nest Wave is off and grayed out.

For those whose Protects are not connected to the Internet, Nest has instructions here.

Once the software update is confirmed, the Protect is good to keep using.
