Security researcher Cody Kociemba discovered that the first- and second-generation Nest Learning Thermostats (sold by Google) remain active data-transmitters even after Google severed remote-control features and ceased support. These units reportedly continue sending logs to Google covering manual temperature changes, motion/occupancy detection, ambient light, humidity and other sensor readings—even though users can no longer manage them from the app or receive software updates. Google maintains the transmissions are meant for diagnostics, but critics argue it’s effectively one-way data collection from hardware that the company no longer supports.

Key Takeaways
– Older Nest Learning Thermostat models are stripped of smart features and official support, yet continue streaming sensor and usage data to Google.
– Google claims the data flow is for diagnostic purposes, but users cannot access remote controls, updates or support, raising concerns about value and consent.
– The episode highlights broader worries about ownership and data-rights in the smart-home era: when a manufacturer abandons hardware, who controls the data pipeline?
In-Depth
In what many see as a troubling twist in the smart-home narrative, Google is facing scrutiny over its treatment of legacy smart-thermostats. The company’s first- and second-generation Nest Learning Thermostats—once heralded as a leap in home comfort and energy savings—have now entered a kind of limbo: they retain hardware capable of collecting detailed environmental and occupancy data, yet their connection to Google’s smart-home ecosystem has been progressively disabled. According to reporting by The Verge, the devices continue uploading information such as manual temperature adjustments, motion detection, sunlight exposure, ambient light, humidity and more to Google’s servers—even after Google disabled remote control functionality and ended software updates.
Security researcher Cody Kociemba discovered the ongoing data feeds while participating in a right-to-repair bounty run by the advocacy group FULU. In devising an open-source project (“No Longer Evil”) to restore smart features to discontinued Nest units, Kociemba inadvertently exposed the fact that these devices remained connected to Google’s backend and steadily transmitting logs. “The logs are pretty extensive,” he told The Verge. He pointed out the irony: while users lost control and support, Google still collected data, yet could no longer assist users when devices fail.
Android Authority backs this account, noting that Google’s own statement confirms that although remote support has ended, the thermostat units will “continue to report logs for issue diagnostics.” The disparity between the feature-set offered to consumers and the data retained by the vendor has drawn disquiet. Meanwhile NewsBytes also reported the story, stressing that users effectively lose smart-capabilities but remain data-generators.
From a conservative perspective, the case underscores two broader concerns: first, the erosion of consumer control and transparency in the connected-device economy; second, the question of business incentives and data-privacy wrapping around legacy hardware. When a company abandons support for a product, ideally the user retains full ownership and control. Instead, Google appears to have quietly transformed legacy Nest units into persistent data-collection endpoints. For consumers who invested in these devices expecting long-term smart-home use, the arrangement may feel misleading: in effect, you own the shell but not the smart ecosystem or service.
Moreover, this scenario raises regulatory and policy questions. If companies can pull support yet continue collecting sensor and usage data, what safeguards ensure that users consent to ongoing data flows, and what limits apply when the original value-proposition (remote control, smart scheduling, voice assistants) has been terminated? From the standpoint of property rights and consumer expectations, the outcome is open to challenge.
In practical terms for homeowners: if you own one of the affected Nest thermostats, you may wish to disconnect it from WiFi or migrate to a supported model—especially if you object to data being shared without full smart-functionality. Google’s approach suggests that smart-home hardware should be viewed not just as a purchase, but as an ongoing service, and consumers should ask: what happens when support ends? This story offers a cautionary tale: the smart-home transition is not just about convenience and energy savings—it’s also about data, control and the long-term relationship with tech providers.
