Why Google Is Collecting Troves of Data From Downgraded Nest Thermostats
Many users are asking why Google is collecting troves of data from downgraded Nest thermostats even after turning off remote control features. Reports from security researchers reveal that older first- and second-generation Nest Learning Thermostats continue sending data such as temperature changes, humidity levels, motion detection, and sunlight exposure. This discovery has sparked questions about data rights, long-term device support, and how much information smart home gadgets silently transmit behind the scenes.
What Data Do Downgraded Nest Thermostats Still Send to Google?
The biggest concern is that downgraded Nest thermostats still share detailed logs with Google despite losing smart functionality. According to researcher findings, these legacy devices upload information on room presence, manual adjustments, ambient light, and environmental readings. While intended for diagnostics, the volume of data raises eyebrows—especially since users no longer benefit from remote access or app-based controls.
Why Researchers Flagged Google’s Ongoing Data Collection
The issue came to light after developer Cody Kociemba built a workaround to restore lost smart features through an open-source project. When cloning Google’s API, he unexpectedly received extensive logs from customer devices, revealing how much data Nest thermostats continue to transmit. This has renewed conversations about right-to-repair, the ethics of sunsetted devices, and whether companies should disable or limit data collection on unsupported hardware.
Should Nest Users Be Concerned About Their Privacy?
Many homeowners now wonder whether they should worry about privacy because Google is collecting troves of data from downgraded Nest thermostats. While the company states that logs are used for performance and safety, experts argue that users deserve clearer disclosures—especially when a device loses features but keeps sending information. As smart home ecosystems grow, transparency, consent, and user control remain key to building trust.
