The Nest learning thermostat is one of the more popular smart home devices available on the market, having been available for a few years now with Nest currently selling their third generation of the product. If you're unfamiliar with the Nest thermostat, it's capable of being connected to WiFi so it can allow you to connect your smartphone to it for easy remote management and temperature control for your home, all from the palm of your hand. Because of its connected nature, you can also set it to turn on or off automatically when you leave the home or when you're on your way back. As the Nest is a connected device it's also capable of interacting with other smart devices around the home, like the SwannOne smart hub for example which allows consumers to connect multiple devices up to it and control everything from one comprehensive application. By all accounts, the Nest Thermostat is a pretty useful piece of technology for many people.
Unfortunately, users have recently been reporting dead thermostats due to a software bug. The bug, which drains the battery of units followed by powering them down, stems from an update that was pushed out in December of 2015, and can cause issues for all models of the thermostat, so whether you have the original or the latest iteration it doesn't matter. That doesn't mean that all users are having the issue of course. For those that are, Nest mentions that they have been able to fix the issue, and have currently fixed the bug on 99.5 percent of units that were affected.
If you still happen to be in the group of people with the problem, Nest has a useful guide to resolving the issue manually, which requires users to unmount the thermostat and connect it up to a PC. Essentially what people need to do according to Nest is perform a manual restart to help things, and to assist in the process the troubleshooting instructions are available online for anyone who needs them. Even though it appears to have taken more than a week for Nest to respond to this bug, with a fix available and a guide to walk users through it all can be well.
