Nest Thermostat Bug Leaves Owners Without Heating (thestack.com)

An anonymous reader writes: Google-owned smart homeware company Nest has asked users to reset their connected thermostats after a software bug forced controllers offline and left owners unable to heat their homes. The company has confirmed that a software update error had caused the thermostat's batteries to drain, therefore making it unable to control the temperature. Users of the smart home device took to social media to express their anger at being left with cold houses. Some feared that the fault had put water pipes under pressure, risking burst plumbing.

If it isn't, there are 5+2 day and 7 day thermostats from Honeywell that can be programmed to expected occupancy schedules and can even be programmed to reverse the heatpump when the seasons change (basically if temp below low-setting, apply heat, if temp above high-setting, apply cool) and these only need a pair of AA batteries to run for more than a year.

      I've had to deal with EMS controller woes in the past- the HVAC people programmed the EMS controllers to basically require a network connection back to their HQ in order to function, else they went into an error-state. When it was pointed-out that there were innumerable points of failure including the LAN at the facility, the WAN, and worst of all, their own HQ's LAN or WAN that could take the entire organization down, only then did it dawn on them that it was a bad idea to so centrally-control the EMS, and they've migrated back to a more sane policy where EMS just runs its set programming until interrupted by the HQ controller.

      We've seen a lot of failure-mode problems lately, to me this points to a lack of quality assurance testing. The trend in having the programmer QA their own code is obviously not providing us with the results that we need and should be stopped.

      A programmable thermostat that has been correctly set up is much more efficient and much less expensive

      Agreed. Now, if we could only take the next step -- making coupled thermostats with humidity monitors more common.

      In my experience, in humid climates the most useful measure of comfort is NOT temperature (or even relative humidity), but rather dewpoint. Comfort is a little more complex than that, but I'd much rather have a device that kept my house in the summer at roughly constant dewpoint (essentially constant absolute humidity), rather than constant temperature. With low humidity, 80+ degrees F can be perfectly comfortable. With 100% humidity, 70 degrees F can be unbearable and led you to be awash in sweat with even minimal exertion. A humidistat is also not quite an answer either, particularly if it tries to maintain static relative humidity -- again, that's not the best measure of comfort either across wide temperature ranges.

      When seasons change, I'm often making on-the-fly adjustments to my programmable thermostat over several weeks, trying to strike a balance between, "I don't really need to have my AC running continuously at 70F just to remove humidity on some days" and "If I set the AC at a high temperature that would work when it's 100F, it isn't warm enough outside to make the AC run and the house will be unbearably humid."

      (I know the Nest does measure humidity and can react to it, though I don't know how effective its programming is in this regard. And I would never use one anyway.)

      I'd save more energy and effort adjusting my programmable thermostat if we just ignored temperature altogether. It's easy to measure, but it's simply not a good measure of human comfort.

      Insulation doesn't make that much of a difference here in Florida. The reason is that we just don't have much of a temperature gradient. In a residential setting, you don't need much cooling at all. Mostly just a way to reduce humidity but the AC unit is the only means available. I have a pretty plain vanilla system and I set it just a few degrees below ambient to ensure that the thing runs and keeps humidity down. Sure there a a few hundred degree days but even then it's only terribly hot for a few hours. Most of the time, my house is within about 5F of the outside temperature so you just can't save much with insulation. My house is about 15 years old. Newer models are adding efficiency features and guaranteeing an average heating / cooling cost of about $100 for the same size unit. I can't measure my heating/cooling cost in isolation since I also do things like cook and do laundry but it's probably around $140 or so. There just isn't a lot to gain in heating/cooling in this area. On the other hand, in the Northeast, I remember $300 gas bills for a place half the size and a smart thermostat might make sense.

      Older thermostat wiring (in 70% of houses) can only really deliver power through the wiring when the heat (or ac) is on/active, so a thermostat must sip power when it is active, and save when it is idle. Ironically, the wire in the wiring scheme that can be used to deliver continuous power is called the "common" wire even though it is actually not too common** ;^)

      Being "smart", the Nest device (as with most "smart" controllers) likely attempts to use various power savings tricks to reduce their native power requirements to a lower average power so it can survive between active times on a battery with this typically wiring. Apparently this update wasn't as smart as it thought it was about conserving power and the energy received during the active time and their efforts were not enough to keep all the smarts going on the battery...

      Of course the older "dumber" smart thermostats, drew such a small amount of power that they didn't need to apply smart power savings tricks to keep things alive between active cycles. Sometimes you can be too clever for your own good and I think the Nest falls into one of those situations...

While we make OK money, I’m convinced she felt the need to single handedly improve the US economy by taking elaborate vacations: Broadway shows in New York City, gambling in Las Vegas, Spa’s in Arizona, sightseeing in San Francisco. The airlines know me so well they ask about my dog when I call to make reservations. His name is Fred.

There are plenty of videos on Youtube to demonstrate how to do this. Within an hour I was up and running.

I also can’t wait for warmer weather when I can crank the heat up to 80 degrees while the love birds are sleeping. After all, who doesn’t want to wake up to an 80 degree home in the middle of June?
