In a concerning revelation for users of older Nest Learning Thermostats, even after Google discontinued remote control functions and support for first and second generation devices, these thermostats continue to upload detailed sensor data to Google. This information, which encompasses a range of metrics from temperature changes to motion activity, raises significant privacy concerns as users believed their devices had been fully disconnected. Researcher Cody Kociemba uncovered this ongoing data flow while working on a project to restore smart features for the aging thermostats, highlighting the complexities of consumer data and corporate transparency.

Researcher finds unexpected data uploads from old Nest devices
Security researcher Cody Kociemba made this surprising discovery while investigating the backend of Nest Learning Thermostats as part of a repair challenge initiated by FULU, a right-to-repair group. The challenge was aimed at reviving smart features for devices no longer supported by their manufacturers. Collaborating with the open-source community, Kociemba developed software named No Longer Evil to restore lost functionality. During this process, he unexpectedly received a torrent of logs from users’ devices, alerting him to the ongoing data transmission between these old thermostats and Google.
This data flow persisted despite Google’s announcement of discontinued support, raising questions regarding the company’s data handling practices. Kociemba‘s investigation revealed that these older models were still active in the data-sharing ecosystem, something that many users were completely unaware of. As part of his work, Kociemba began to dig deeper into the nature and specifics of the data that was still being sent to Google, uncovering a significant amount of information not previously disclosed to consumers.
What Nest thermostats keep sending to Google
Although remote control features have ceased to function, older Nest Learning Thermostats persist in sending a variety of sensor data to Google. The types of data that continue to be transmitted include:
- Manual temperature changes
- Occupancy detection (whether someone is present in the room)
- Sunlight impact (tracking when sunlight shines on the device)
- Temperature readings
- Humidity levels
- Motion activity
- Ambient light data
The volume of logs being sent was substantial, leading Kociemba to deactivate the incoming data stream. He initially had not anticipated that the devices would remain connected to Google following the discontinuation of their smart functionalities. Despite Google’s prior assertions that unsupported models would “continue to report logs for issue diagnostics,” the reality appears much more complicated.
Without active support or utility, the ongoing data flow raises ethical concerns regarding consumer privacy and device transparency. Users are left questioning what data is being collected by Google and for what purposes, especially since the company can no longer assist in troubleshooting or offering support for these outdated models.
Why this discovery matters
The implications of this revelation are far-reaching, as many users had assumed the disconnection from Google servers due to the end of support meant they would also regain a degree of privacy. The fact that these devices continue to send data creates a unilateral stream of information that benefits the corporation much more than the users. The lack of clarity surrounding what data is transmitted and the inability for users to effectively manage this outflow heightens concerns about corporate governance and user autonomy.
With modern consumers increasingly prioritizing data privacy, the persistence of data-sharing even after support has ceased contradicts expectations about technology and ownership. Users who believed they had severed ties with the service may find themselves still indirectly contributing to Google’s data ecosystem without their knowledge or consent. This signifies a problematic precedent when it comes to consumer electronics and user expectations.
The FULU bounty that sparked the discovery
The discovery of the ongoing data uploads was fueled by FULU’s bounty program, which encourages developers to restore functionality to obsolete devices. This initiative aims to empower users and innovators alike in finding viable solutions for older technology. In recognition of the effort involved, FULU rewarded Kociemba and another contributor known as Team Dinosaur with the top bounty of $14,772. Their work not only demonstrates the potential of community-driven repair but also raises critical questions regarding how companies maintain control over data from devices they have abandoned.
This bounty program showcases the importance of sustainable technology practices and highlights a growing trend in the right-to-repair movement. By empowering developers and consumers alike to reclaim agency over their devices, such initiatives play a key role in encouraging more responsible corporate behavior and enhancing transparency regarding user data.
Ways to stay safe if you still use an old Nest thermostat
For users who continue to utilize these older Nest thermostats, a range of measures can be taken to safeguard personal privacy. To minimize exposure and protect against unwanted data sharing, here are some practical suggestions:
Review your Google account activity
Begin by inspecting what Google has tied to your home devices. By visiting myactivity.google.com, you can check thermostat logs or events that may seem unexpected. This proactive step aids in understanding data flows from your devices.
Place the device on a separate Wi-Fi network
Creating a guest network can keep the thermostat segregated from your main devices. This measure limits the thermostat’s ability to reach other devices on your network, thus enhancing your overall security.
Block outbound traffic when possible
Certain routers offer the option to cut off individual devices from sending data to the internet. By implementing this feature, you can halt log uploads while still allowing the thermostat to manage heating and cooling functions.
Disable any remaining cloud features
If the thermostat’s settings menu provides options for cloud features, ensure that remote access and online diagnostics are disabled. Even basic controls can significantly reduce the flow of data.
Remove old device associations from your Google account
Regularly verify your connected devices in Google settings. Removing any outdated Nest entries that no longer serve a purpose prevents leftover links that may still be transmitting data.
Adjust router settings that report device analytics
Some routers may collect analytics from connected devices. Turn off any analytics reporting to the router manufacturer, minimizing your virtual footprint with unsupported smart products.
Plan your replacement
Given the loss of security updates for unsupported devices, consider upgrading to a model that continues to receive updates and support. This not only enhances functionality but also secures your home network.
Summary
The revelation that older Nest Learning Thermostats continue to send data to Google, despite the loss of support, has sparked significant concern among consumers. This situation brings to light key issues surrounding corporate responsibility, transparency, and consumer rights in an increasingly digital world. Users are urged to take immediate steps to protect their privacy and be more informed about the technology they employ in their homes.
