Back in April we reported that Nest, the now Google owned company that makes the Nest thermostat, pulled it’s smoke/carbon monoxide detector, Nest Protect,  off the market. They made this decision after they internally uncovered a flaw that could have been dangerous with the product.

Although no accidents were reported, engineers at Nest discovered that a wave to silence the Nest Protector smoke/carbon monoxide detector could accidentally be triggered causing the alarm to stop even in a situation where smoke or carbon monoxide were present.

Technobuffalo reports that 0.15 percent of households in the US, UK and Canada are exposed to dangerous levels of carbon monoxide each year. That translates to roughly one million households across all three countries.

Nest has started selling the Nest Protect device again, but now for just $99 as opposed to the $119 they charged when the device was first introduced.

Consequently, the safety issue has not been fixed yet, so for the time being the company has disabled the wave to silence feature. Nest says that when they have the issue worked out they will be able to send out a firmware update with the fix.
