Pros

  • Effectively regulates temperature across multiple areas, ensuring consistent comfort throughout your home.
  • Learns and adapts to your preferences over time, making everyday adjustments smarter and more personalized.
  • Mobile app offers highly convenient remote control, allowing you to tweak settings from anywhere with internet access.
  • Energaving features automatically adjust temperature based on occupancy, helping reduce utility bills.
  • User interface is sleek and modern with an intuitive design and clear display.
  • Installation is generally easy for those with basic wiring knowledge; includes helpful wirdentifying stickers to assist setup.
  • Provides accurate temperature readings after a short adjustment period.
  • Setup with Google Home and iPhone is straightforward and quick.
  • Functions reliably and consistently with no major performance issues reported.
  • Preferred over some other Nest models for its balance of features and price.

Cons

  • Installation can be tricky if you lack wiring experience or don’t have a "c" wire, which some users may need to create or repurpose.
  • Depends heavily on a stable Wi connection; loss of internet can disrupt remote control and notifications.
  • Manual temperature adjustments on the thermostat unit are not very intuitive and lack clear markings for mode changes.
  • Temperature units can only be changed through the app, not directly on the thermostat itself.
  • Designed primarily for U.S. heating systems; not compatible with Turkish boilers or many European systems without an additional heat link device (not included).
  • The default white plastic backplate may clash aesthetically when installed on walls with older paint or textures, and no matching backplate color is available for the "Fog" model.
  • Limited support for more complex or multtage HVAC systems compared to higher-end Nest models.

Bottom Line

The Google Nest Thermostat in Fog is a smart, stylish, and affordable choice for those wanting easy remote control, energy-saving features, and a thermostat that learns your habits — especially if your home uses common U.S. heating systems and you’re comfortable with a bit of DIY installation. However, if you have a complicated or European HVAC system, or if you value more advanced in-unit controls and better compatibility, you might want to look at higher-tier Nest models or consider additional accessories. Overall, it’s a solid pick for savvy users who prioritize app control and energy efficiency.
