Nest 1st Gen and 2nd Gen Thermostats Support Ending October 25, 2025 Google announced it will stop supporting the first and second generation Nest thermostats from October 25, 2025. Key points and community discussion from the Hubitat forum include: --- What is Happening? Google will no longer support Nest 1st and 2nd gen thermostats after 10/25/2025. Devices will continue operation locally but will lose integration with the Nest or Home apps. API support will be removed, meaning no remote app controls and no integration via services such as Hubitat. --- Impact on Hubitat Integration Direct Hubitat integration with 1st and 2nd gen Nest thermostats will no longer work since the API will be gone. Control will be limited to the physical thermostat dial. Newer Nest devices (like Gen 4/Nest Thermostat E) may have better future support due to Matter protocol compatibility. --- Alternatives and Recommendations from the Community Locally Controlled Thermostats: Zigbee or Z-Wave thermostats with local control for simple HVAC setups (e.g., 1H/1C or single-stage heat pumps). Ecobee Thermostats: Often recommended for better reliability and local control options. Can integrate with Hubitat through cloud integration or via Home Assistant for local control. Matter Protocol: Latest Nest thermostats support Matter, enabling local control without cloud dependence. Matter support for thermostats currently limited to basic functions (mode, target temperature, current temp). Hubitat Matter Thermostat Driver: A driver exists but functionality may be limited due to manufacturer firmware. Users advised to test before fully committing. --- Concerns and User Experiences Users with multiple thermostats face costly replacements. Frustration expressed over planned obsolescence tied to cloud service dependency. Some caution around Google’s ability to override settings remotely (as experienced with Nest Secure and Protect). Suggestions to consider compatibility and future-proof options carefully. --- Specific Community Insights @aaiyar: Suggested ecobee with Home Assistant to maintain full remote control and local fallback. @GuyMan: Noted Nest Gen 4 supports Matter but limited to US release; community members outside US have fewer options. @croweflight: Recommended Go Control Z-Wave thermostat for full local control and native Hubitat support. @LearningHubitat: Described detailed stepwise approach using Ecobee and Home Assistant for robust local plus remote control. --- Summary Google will phase out cloud and app control for older Nest thermostats, ending their smart home integration. Hubitat users relying on integrations will lose functionality with 1st and 2nd gen Nest devices. Alternatives exist but may require hardware replacement or added complexity (e.g., Home Assistant). Matter promises future-proof local control but currently has limited thermostat function support. Users are encouraged to carefully evaluate replacement options before transitioning. --- Helpful Links and Resources Hubitat Ecobee Integration Documentation Discussions on Matter thermostat drivers and bugs from Hubitat Community forums. --- This change highlights the importance of choosing smart home devices with strong local control capabilities to avoid disruptions caused by discontinued cloud services.
