Nest Halts Sale of Protect Because of Safety Concerns, Will Be Updating Software Soon
Nest CEO Tony Fadell announced today that it would stop selling its Protect fire alarm while it reconsidered a key feature of the device: The ability to "wave to hush" a warning alarm. He explains that the issue is with the alarm's motion detection system.
The system is supposed to be able to silence a warning with the wave of your hand but further tests have revealed that the feature could be triggered by accident during a real fire. There's danger to this because, it could result in a delayed response to actual danger. From the company:
We discovered that movements near the product that are not intended as a wave can be misinterpreted by the Nest Wave algorithm. If this occurs during a fire, this could delay the alarm going off. So, we are disabling this feature until we have a proper solution.
This is an issue we observed while performing laboratory tests. To the best of our knowledge, no customer has experienced this issue.
If you already have a Protect, the wave feature will be automatically disabled within the next day. You will need to connect your alarm to your Wi-Fi in order to get the updated version of Nest's software.
The company isn't changing the hardware, just the software, so for now, even if you have a Protect, all you need to do is wait for the software update. More information is on a Q&A about the issue here.
