From the horse’s mouth
As the Internet Of Things starts to evolve slowly, there has been news about a home-automation device being “refreshed” with new firmware with the ability for equipment in current use to benefit from the software update.
Here, the Nest thermostat will benefit from a large software update which improves its learning abilities and preemptive operation functionality. Rather than having the user spend a lot of time adjusting the system to suit their lifestyle, this thermostat can learn your requirements more quickly. As well, Google published an API so it can interact with other devices and become part of the “Internet Of Things”.
Google tweaked the operation algorithm using a continual “opt-in” feedback loop involving existing users and this could be seen as a way to further fin-tune any machine-learning or “preemptive operation” algorithms. There is also other functions like time and outdoor temperature / humidity display abilities as well as a “system check” function to help you troubleshoot your central heating or air-conditioning, especially before a season change.
The Nest thermostat will receive the updates by itself as long as it is connected to your home network and the Internet. This allows for a hands-off update process and is an example of what should be done to allow for reliable and secure operation of equipment that is part of the “Internet Of Everything”.
