Nest has put a halt to sales of their connected Nest Protect smoke detector over concerns that the alarm could be unintentionally deactivated. Protect smoke alarms have a “Protect Wave” feature which allows users to deactivate the alarm when it’s activated under not dangerous conditions (say, smoke from cooking) by waving at the alarm. The Nest Wave feature has been found in Nest’s own testing to be possible to be deactivated under “a unique combination of circumstances”.
