After being withdrawn from the market two months ago, the Nest Protect smoke and carbon monoxide detector has been re-introduced with its waving de-activation mode disabled.
The line of Nest products was considered important enough for Google to pay US$2.3bn to buy the company. Yet the Nest Protect smoke and carbon monoxide detector was deemed unsafe last April, after it was found the feature of the alarm that allows consumers to de-activate it by waving underneath it was faulty and potentially hazardous.
The product has been relaunched on Nest’s website at a lower price than before it was removed, from US$130 to US$99.
The smoke and carbon monoxide detector was wildly heralded as a sign of the future growth of the internet of things (IoT), whereby a homeowner could control multiple utilities within the house through his or her smartphone or other devices.
Nest also revealed some statistics, given the fact its devices are always connected to the internet and able to monitor raw data found in the devices.
According to its figures, Nest Protect’s data suggests at least 1m households across the US, UK and Canada are exposed to high levels of carbon monoxide each year.
