Nest Labs has issued an official recall of all of the Nest Protect Smoke + Carbon Monoxide Detector units it has sold, about 440,000 in all. Sales of the device were halted early last month after company CEO Tony Fadell issued a letter saying the fire alarm could be delayed under certain circumstances. As previously reported, Nest offers an over-the-air update that disables its Nest Wave feature, which caused the possible issue. The company has yet to receive any reports of incidents, injuries, or property damage from the potential issue. Customers can also seek a full refund for the alarm — Nest can be contacted at (800) 249-4280 or at nest.com. [via Gizmodo]
Update: Nest told The Guardian nothing has changed since the company’s initial announcement, and a Nest spokesman said “we’ll be bringing Nest Protect back on the market in a few weeks.”
