Nest removes Protect smoke alarm from shelves due to safety concerns

The Lord giveth and he taketh away, in all spheres of life – even technology, as no sooner had we seen the release of the Nest Learning Thermostat in the UK, we've been relieved of its partner in smart home gadgetry, the Nest Protect smoke alarm.

Protect has been withdrawn from sale following Nest's discovery that the "Wave" feature, which allows users to turn the alarm off with a wave of their hand, could potentially be unintentionally activated. This could theoretically lead to a delay in the alarm triggering to warn of a real fire... though Nest notes that it hasn't had any customers complain about such an issue.

Obviously, though, it's a major potential problem, hence the product withdrawal.

Tony Nadell, CEO of Nest, wrote in a blog post: "We feel that the best and safest thing to do is to immediately disable the Nest Wave feature to resolve the issue and remove any safety concerns. While we fix Nest Wave, we have also halted sales of all new Nest Protect alarms to ensure no one buys an alarm that needs an immediate update."

Those who have their Protect alarm connected to their Nest account via Wi-Fi will automatically have the feature turned off, and those who aren't hooked up wirelessly are advised to do so immediately. If you don't have Wi-Fi, or can't connect to the net for whatever reason, then you should stop using your Protect – you'll get a refund.

Once the Nest Wave problem is fixed, the alarm will go back on sale.
