Google has ended support for its first- and second-generation Nest Learning Thermostats, a move that sparked frustration among users. The discontinuation, announced in October 2025, left many questioning why Google couldn't extend support for devices that are relatively simple in terms of software demands. While the thermostats still function manually, they are now disconnected from external apps and accessories, and no further software updates will be provided.
For those unwilling to upgrade, there are two main alternatives: recycling the device or exploring third-party solutions. Google offers a free recycling program, complete with a prepaid shipping label, but users must perform a factory reset to ensure no personal data remains. Alternatively, the open-source project No Longer Evil aims to revive the old smart features by flashing custom firmware onto the devices. However, this process carries a risk of bricking the thermostat, rendering it unusable even in its basic form.
Before deciding on an upgrade, it's worth considering whether a new smart thermostat is truly necessary. Modern models offer advanced features like occupancy detection and cloud-based weather data integration, which can help reduce energy bills. However, for households with predictable routines, the built-in scheduling of older Nest models may suffice. Simple adjustments, such as tolerating slightly warmer or cooler temperatures, can also lead to significant savings without the need for a new device.
For those considering an upgrade, it's advisable to check for rebate programs offered by energy providers. These rebates can make high-end models more affordable, as was the case with a recent purchase of an Ecobee thermostat.
