Nest Smoke Alarms Can Tell Smoke From Steam Now, But Wave Feature Still Doesn’t Work

When it comes to smoke detectors, the only thing worse than a screeching alarm when there’s no fire in your home is when the alarm doesn’t go off when there is a real fire. One of these problems is annoying, and the other can be life-threatening. In lab tests and real-life situations, users of the Nest thermostat have reported both issues, and Google-owned Nest has really only been able to fix one of them.

Nest thermostats were recalled and taken off store shelves back in May because of an issue where a glitch in the system that lets users shut off false alarms by waving at the unit. While this is easier than hauling out a chair or stepstool or frantically waving a newspaper at the ceiling, my time-honored methods to shut down false alarms, the company’s tests found that it could prevent the alarm from going off in case of an actual fire. Oops.

The company’s solution at the time was to push out a software update that…disabled the wave-to-shut-up-the-alarm feature. The feature simply hasn’t returned, which keeps customers safer, but is less fun.

What about the false steam alarms? Nest has solved that problem, claiming that false alarms due to humidifiers or, presumably, boiling pots of pasta have been reduced by half thanks to new smoke-detection algorithms.
