Nest Halts Sales of Smart Fire Alarm After Discovering Dangerous Flaw

fructose writes: "The Nest Protect has a flaw in its software that, under the right circumstances, could disable the alarm and not notify the owners of a fire. To remedy this flaw, they are disabling the Nest Wave feature through automatic updates. Owners who don't have their Nest Protects connected to their WiFi net or don't have a Nest account are suggested to either update the device manually or return it to Nest for a full refund. While they work out the problem, all sales are being halted to prevent unsafe units from being sold. There have been no reported incidents resulting from this flaw, but they aren't taking any chances."

    I think a fire alarm is an instance where I'd like something to have as simple and foolproof a mechanism as possible. I suppose a smart alarm could perhaps call the emergency services or something... but I'd still probably combine it with a bog standard fire alarm.

      Yes. That's why fire sprinklers are so successful. There's nothing between the water and the fire except a low-melting-point component in the sprinkler head.

      This is an example of webcrap-level programmers doing things they're not qualified to do. I'm beginning to think that "Internet of Things" programmers should be required to have Registered Professional Engineer credentials, like structural engineers.

      YMMV, but my house is wired for a burglar alarm. It is monitored. All the smoke detectors are wired to the main alarm. If one of them goes off, the alarm system notifies the monitoring company, and they call me to see if there is a fire (actually looking for false alarm). If I don't respond, they send the fire department. It is the ONLY reason there is a land line at my house these days.

      My understanding is that Nest does this via Wifi. In the event of an emergency, I trust the POTS far more than the cable internet and wifi to call the cavalry. Perhaps one day Nest will make this all fool proof. But until that day, I will stick with the land line/alarm monitor.

      Oh, the monthly cost to monitor is like $6.00.

      The fire sprinklers with the visible glass tubes are activated when heat causes the liquid inside to expand, shattering the glass and opening the valve. No melting occurs.

    I did not RTFA in depth but I am surprised that they did not have a mechanism to fix it remotely via updates of something.

    Straight from the summary:

    They did a test of that thing on the news the other day; it detected carbon monoxide and smoulder-type fires just fine.

    What it failed to do was detect an actual fire that didn't produce much, if any, smoke.

    Maybe they should just relabel it as the "Nest Toxic Chemical Detector."

      That's because it doesn't have both an ionizing and a photoelectric sensor. One is better with smoldering fires (photoelectric), the other one with a hot fire producing small particles (ionizing).* The interlinked Kiddie units I have do both.

      Heat detection really isn't a great option compared to ionizing or photoelectric, but does work better in "dirtier" environments say located near an old furnace in a basement or other dusty/dirty areas.

    Completely agree. This is somewhat along the same line: I don't want a smart fridge - someone might hack in and turn up the temp just enough so I don't notice but enough to cause me to get food poisoning from the warmer temp. Of course they'd disable the temp alarm in the process. I don't want someone turning on my smart toaster and burning my house down, or causing my dishwasher or washing machine to flood the house. That's the problem with the internet of things - it will never be 100% secure.

    I'm sure we will see more problems with the internet of things. Just wait until lulz kids figure out how to make smart smoke alarms beep continuously., so people disable the power, or turn the heat up to 100 and then down to 10 ( Fahrenheit). There's not shortage of psychos who like to screw with people (see: webcam hacks and 'slaves'). So it's a matter of time.

    Critical life safety devices like Smoke detectors should be a local loop only. You can interconnect, but don't connect to the internet or phones.
    If you want a smart one, make it redundant and in addition to the local only alarms. Hook it up to something outside or your alarm company.This is to call the fire department when no one is home. I.e. this is for saving your property.
    And control devices like your thermostat should have a local override switch that disables, in hardware, all smart features and turns it into a dumb device
