Google announced the end of support for early Nest Thermostats in a support document earlier this year that largely flew under the radar. As of October 25, first and second generation units released in 2011 and 2012, respectively, will be unpaired and removed from the Google Nest or Google Home app.
Users will no longer be able to control their thermostats remotely via their smartphone, receive notifications, or change settings from a mobile device. End-of-support also disables third-party assistants and other cloud-based features including multi-device Eco mode and Nest Protect connectivity.
My father got and installed two of the newer nest thermostats, and they are bar none two of the most annoying tech devices I’ve ever had the misfortune of having to fix. Have literally spent hours debugging them when changing the wifi password, they don’t support wpa3, and the setup app feels like a half assed student project. I know this audience probably isn’t interested in getting one, but if one of your family members gets some for free, do NOT let them install them.
