Google just delivered another gut punch to loyal Nest users. In March 2025, the tech giant quietly discontinued two of its most beloved smart home devices: the Nest Protect Smart Smoke and CO Alarm and the Nest x Yale Smart Lock. Fans are absolutely furious, and honestly, who can blame them?
Google quietly axed beloved Nest devices in March 2025, leaving loyal smart home users absolutely furious and betrayed.
The discontinuation comes as part of Google‘s broader hardware lineup reduction. Translation? They’re dumping products that don’t fit their shiny new vision. Both devices relied heavily on the legacy Nest app, which Google is aggressively phasing out in favor of the Google Home app. Apparently, keeping things working wasn’t worth the hassle.
What makes this particularly infuriating is how Google handled it. Users reported difficulty buying Nest Protect units well before the official announcement. The writing was on the wall, but Google kept quiet. No new models are planned for either device. Zero. Zilch.
The pain doesn’t stop there. First and second-generation Nest Learning Thermostats are getting the axe too, with support officially ending October 25, 2025. These devices will revert to basic thermostat functionality, losing all their smart features.
App controls? Gone. Scheduling? Bye. Energy reporting? Not happening. Only third-generation models from 2015 or newer survive the purge.
Google’s rationale centers on streamlining their platform for innovation. They’re pushing users toward their modern ecosystem, abandoning anything that doesn’t play nice with current security protocols and app features. This aligns with their broader shift from Google Assistant to Gemini.
The community backlash has been swift and harsh. Users are expressing serious frustration about device obsolescence, especially considering the expectation that foundational home devices should last years, not get bricked by corporate strategy shifts. European users are particularly upset, with no upgrade options available.
Google is offering new devices like the First Alert Smart Smoke & Carbon Monoxide Alarm and Yale Smart Lock with Matter as replacements launching in late 2025.
Once support ends, these devices lose remote control capabilities, app notifications, automation features, and integration with Google Home routines. They’ll function manually but won’t be “smart” anymore.
For smart home owners, it’s a stark reminder that cloud-dependent devices live and die by company whims.
