Nest Thermostat Support Discontinued
Google ceased support for its first and second-generation Nest Learning Thermostats in October 2025. This discontinuation means these older models no longer receive software updates and are disconnected from external apps and accessories, though basic on-device temperature adjustments and auto-schedule functions remain operational.
Impact on Users
The decision to end support for these thermostats, which are typically long-term household fixtures, has prompted user frustration. Google offered discounted upgrades to its fourth-generation model, but this option may not appeal to users not wishing to further invest in the Google ecosystem.
Open-Source Alternative: No Longer Evil
One alternative for affected users is an open-source project called "No Longer Evil." This project allows users to flash custom firmware onto their devices, potentially restoring advanced functionalities lost with Google's support withdrawal. The project offers its own cloud platform, or users can integrate it with a self-hosted server or the Home Assistant ecosystem.
Installing custom firmware carries a risk of bricking the device, rendering it permanently unusable. This process is recommended for users comfortable with technical procedures, as a failed installation could leave them without a functional thermostat.
Recycling Program
For those not interested in technical modifications, Google provides a free recycling program for the discontinued thermostats. This program includes a prepaid shipping label, simplifying the disposal process for users.
