Google has announced the end of software support for its early Nest Thermostats, specifically the 1st and 2nd generation Nest Learning Thermostats. This decision includes discontinuing updates and remote control features, making these older devices functionally limited. Additionally, Google will cease selling Nest products in Europe, citing complications in managing the existing models. As a result, users may soon find their old Nest thermostats losing remote access and functionality. However, there may be opportunities for discounts on upgrades for those looking to replace their outdated devices.
