July 19, 2025, Mountain View Google has announced its latest Nest Thermostat, designed to save energy without relying on the cloud. The new model uses local AI processing to learn your daily habits — like when you wake up, leave the house, or go to sleep — and adjusts your home’s temperature automatically.
Unlike earlier versions, the new Nest does not send data to Google’s servers. All activity and learning take place on the device, improving privacy and response time.
What’s New in the 2025 Nest Thermostat
- On-device AI: Learns when to heat or cool each room
- Room-specific sensors: New Nest Minis track comfort in each zone
- Touch dial redesign: Sleek interface with quicker response
- Battery backup: Keeps settings during power outages
- Offline mode: Fully usable without Wi-Fi
Google says the new model cuts household energy use by up to 21% more than the 2023 version, based on early testing in the U.S. and Europe.
Privacy and Performance
With growing concerns over smart home surveillance, Google has emphasized privacy. The company states that the device does not store audio, video, or behavioral data in the cloud unless explicitly enabled by the user.
All commands and schedules are processed directly on the device using a custom Google Tensor Nano chip built for edge AI.
Pricing and Availability
The new Nest Thermostat starts at $149 and is available today in the U.S., UK, Canada, Germany, and Australia. A bundle with two Nest Minis costs $199. Orders ship starting Monday.
It is compatible with most HVAC systems and can be installed in under 30 minutes. Google is offering up to $50 in energy rebates through select utility partners.
Conclusion
Google’s newest Nest Thermostat shows how smart home tech is evolving. With local AI, privacy-first design, and real energy savings, it’s a step forward for homes that want comfort and efficiency without giving up control.
