Back in October, Google ended software support for the original and second-generation Nest Learning Thermostats. On the surface, that doesn’t seem totally unreasonable, considering those original devices are roughly 14 years old at this point. If you have one, you can still use it as a thermostat, but it will no longer connect to the internet. As a result, you can’t connect to it using the Nest or Google Home apps.
That may not seem like a big deal, except that the single greatest thing about using a Nest Thermostat wasn’t the fact that it would learn your habits and create routines, or that it would detect when you’re not home and adjust accordingly. No, the best thing about using a Nest Thermostat was that you could open the app and turn on the furnace before you head home from the company Christmas party. The best thing about Nest was that it took the single most boring thing in your home and made it smart.
The problem is, those devices are still working just fine. In many homes, the hardware works exactly as well as it did the day it was installed. I know this to be true because ours is one of them. We have a second-generation Nest Learning Thermostat and the only thing wrong with it is that Google decided to kill its absolute best feature.
The smart home dream
Nest was started in 2011 by Tony Fadell, whose primary design accomplishment before that was that he invented the iPod. The idea was simple—take the most boring household hardware device and turn it into magic. The original Nest Learning Thermostat was both incredibly well designed and also magically smart. It learned user behavior, saved energy, and looked good doing it. Nest quickly became the most recognizable name in the beginning days of the smart-home market.
Google bought Nest in 2014 for $3.2 billion, signaling how important the company believed the connected home would become. For a while, Nest operated semi-independently, expanding into products like smoke detectors, cameras, and doorbells.
Eventually, Google folded Nest back into its hardware division. That shift brought tighter integration with Google Assistant and a unified smart-home platform, but it also marked the end of Nest as a standalone brand with its own roadmap.
Google changes direction
Over the last decade Google has reworked the Nest lineup into a broader Home ecosystem. Some early devices aged out as the company consolidated platforms, rewrote its smart-home APIs, and shifted from “Works with Nest” to “Works with Google Home.”
